How to Write a "Material A vs B" Article That Wins RFQs (Template)

A "Material A vs B" article earns quote requests when it helps a buyer decide for their own application, not when it crowns a winner. The structure that works is simple: name the exact grades, give a short sourced comparison table, explain each trade-off around a buyer question, write conditional recommendations, and end with a clear list of what to send you for a quote. Below is a reusable template, with aluminum vs stainless steel as the worked example.

Why most material comparison articles don't produce RFQs

Most supplier comparison pages fail in the same four ways:

• No application context. A generic property list does not tell a buyer sizing a marine bracket anything different from a buyer sizing an indoor enclosure.
• Material families instead of grades. "Aluminum" and "stainless steel" are families. A comparison that never names 6061, 304 or 316 cannot be checked, so engineers do not trust it.
• An absolute winner. "Stainless is better" is true for some jobs and wrong for others. Buyers who know that stop reading.
• No next step. The article ends without telling the reader what information you need to quote, so the easiest action is to keep researching somewhere else.

Google's own guidance points the same way. Its advice on creating helpful, reliable, people-first content asks whether content offers original information and clear sourcing, and states that trust is the most important part of E-E-A-T. Its guidance on writing high-quality reviews is written for product reviews, but it maps closely onto material comparisons: share quantitative measurements, discuss benefits and drawbacks, and explain which option suits which uses or circumstances.

The template at a glance

Section	Job it does	What to include
Answer-first summary	Gives the decision rule in 2–3 sentences	"Choose A when..., choose B when..."
Scope	Stops readers misapplying the advice	Exact grades, tempers and the applications covered
Comparison table	Lets a buyer compare in seconds	4–6 rows, sourced figures, qualitative notes where no source exists
Criterion sections	Answers each buyer question in depth	Weight, corrosion, fabrication, strength, finish and cost
Conditional recommendations	Turns trade-offs into decision rules	Condition, material, caveat
"What to send us for a quote"	Converts readers into RFQs	Drawing, grade, environment, quantity, finish, documents
FAQ	Catches long-tail questions	3–5 short, direct answers

Step 1: Name the grades and the application first

Before writing, decide exactly what you are comparing and for whom. State it in the opening lines so readers can self-select.

Example: "This guide compares 6061-T6 aluminum with 304 and 316 stainless steel for machined brackets and enclosures used outdoors, including coastal sites. It does not cover castings or high-temperature service."

Then list the questions your buyers ask on real sales calls. For most material comparisons they reduce to five: Will it survive my environment? How much will it weigh? How hard is it to make? Is it strong enough for my load? What will it cost to finish and ship? Each becomes a section.

Step 2: Build the evidence file before you write

Every number in the article needs a source a buyer can check. Good sources, in rough order of strength:

1. Standards and standards-based tables. For example, the British Stainless Steel Association publishes physical properties of stainless steels to BS EN 10088-1.
2. Industry association handbooks. The Aluminum Association's International Alloy Designations and Chemical Composition Limits and the Specialty Steel Industry of North America's Designer Handbook: Stainless Steel for Machining are examples.
3. Batch documentation. A mill test report certifies a material's chemical and physical properties; under EN 10204, a type 3.1 certificate is issued by the manufacturer, declares compliance with the order and supplies test results.
4. Your own data. Incoming inspection records, cycle times, tool life and field returns. This is the evidence competitors cannot copy, and it is the kind of original information Google's guidance rewards.

Two rules keep the evidence honest:

• Published values are nominal. The Aluminum Association's alloy document says its calculated densities are nominal values that should not be specified as engineering requirements. Say the same in your article, and tell readers to confirm with batch certificates.
• Disclose conflicts as ranges. If two datasheets disagree for the same grade, show the range and name a source. Never average numbers or pick the flattering one.

Step 3: Build a short, sourced comparison table

Keep the core table to four to six rows of criteria that actually change a buyer's decision. Push caveats into the text around it. Where you have no verified figure, describe the difference qualitatively and say what the reader should check.

Example: 6061 aluminum vs 304/316 stainless steel

Criterion	6061 aluminum	304 / 316 stainless steel
Density (nominal)	2.70 × 10³ kg/m³ (Aluminum Association)	304: 7,900 kg/m³; 316: 8,000 kg/m³ (BSSA, BS EN 10088-1)
Chloride environments	Protective oxide film; check exposure and finish	316 adds 2–3% molybdenum for better pitting resistance than 304 in chloride environments (SSINA)
Machining	Insert your own cycle-time and tool-life data	High work-hardening rate; needs rigid setups and steady feed (SSINA)
Mixed assemblies	Can corrode when in wet contact with stainless	The more noble metal in the pair, so the aluminum side is the one at risk; isolate the joint (BSSA)
Finish options	Your anodizing and coating options	Your brushed, polished or passivated options

From the two density sources, a 6061 part weighs roughly one-third as much as a 304 part of the same volume (2,700 vs 7,900 kg/m³). That is a fair, checkable sentence because both inputs are linked.

Step 4: Write each criterion section around a buyer question

Open each section with the question as the heading, answer it in the first sentence, then add context, evidence and the caveat.

Weight. Explain why the difference matters for this buyer: freight, one-person installation, or, in the other direction, stability for heavy bases. A bare ratio without a reason is trivia.

Corrosion. Match grade to environment, not family to family. Name the exposures you cover: indoor dry, outdoor inland, coastal, washdown, de-icing salt.

Example: "For coastal installations, specify 316 rather than 304. Its 2–3% molybdenum gives it better resistance to chloride pitting, according to SSINA's designer handbook."

Cover mixed assemblies too. The BSSA explains that bimetallic corrosion needs moisture: dry metals do not suffer it, a large stainless area against a small aluminum area accelerates attack on the aluminum, and in its field example, bolts fitted with sound insulating washers caused no pitting on the surrounding aluminum. A sentence like that answers a question buyers often forget to ask until a field failure.

Fabrication. This is where your own shop knowledge is most valuable. SSINA notes that austenitic stainless steels have a high work-hardening rate and that dwelling or very light cuts should be avoided. Add what that means in your plant: typical setups, finishing steps and where lead time changes. Use your own cycle-time data if you have it, and label it as yours.

Strength. Never compare "aluminum strength" with "stainless strength." Always pair any figure with alloy, temper or condition, and the property measured (yield, tensile or hardness), with its source. If you lack a sourced figure, say strength depends on grade and temper and invite the reader to send their load case.

Finish and total cost. Avoid publishing prices. Instead, list the cost drivers (material, machining time, finishing, freight weight, certificates) so the buyer understands what moves the quote.

Step 5: Replace the winner with conditional recommendations

Every recommendation should carry a condition, a material and a caveat.

Example:

• Choose 6061 aluminum when part weight drives freight or handling cost and the part will not sit in sustained chloride exposure, or is suitably finished for it.
• Choose 316 stainless for coastal or salt-exposed outdoor parts where pitting resistance matters more than weight.
• Choose 304 stainless for general indoor or mild atmospheric service where 316's extra alloy content is not needed.
• If the assembly mixes both metals in a wet environment, isolate the joint whichever material you choose.

This format gives buyers a decision rule they can forward to colleagues, which is exactly what a procurement team needs.

Step 6: Turn the article into an RFQ path

The comparison builds confidence; the RFQ section converts it. Add a short "What to send us for a quote" block after the recommendations and link to it from the summary.

Example: what to send for a quote

• Drawing or 3D file, with tolerances. If you use GD&T, note the standard, such as ASME Y14.5.
• Material grade, or "undecided between A and B" plus the operating environment.
• Annual and per-order quantities.
• Finish, coating or surface requirements.
• Required documents, such as an EN 10204 3.1 material certificate.
• Delivery destination and target date.

Offer a low-commitment option too, such as "Not sure which grade? Send the drawing and environment and our engineers will recommend one." No article guarantees conversions, but this removes the most common reason a qualified reader leaves without contacting you.

Make it easy for search engines and AI answers to use

Google states that there are no extra requirements or special optimizations to appear in AI Overviews or AI Mode. The same fundamentals apply: keep important content in text (build the table in text, not as an image), link to the article from related product and capability pages, and make any structured data match the visible text. An answer-first summary and question-style headings also make each section easy to quote accurately.

Write headings in the terms buyers search with. Google's SEO starter guide notes that experts and newcomers often use different words, so cover both, such as "6061 vs 316" alongside "aluminum or stainless steel for outdoor brackets."

Pre-publish checklist

• Every grade is named explicitly, never just the material family.
• Every number links to a source a buyer can open, and nominal values are labelled as nominal.
• Conflicting values are shown as a range, not averaged.
• The table has six rows or fewer, with caveats in the text.
• Each recommendation states a condition and a caveat.
• Shop-specific facts (lead time, MOQ, capability) are confirmed by the person who owns them.
• The "what to send for a quote" block is present and linked from the summary.

FAQ

How long should a material comparison article be? Long enough to answer every buyer question in your scope and no longer. Use the table for quick comparison and the sections for nuance; cut anything that does not help a buyer decide.

Can I publish property figures from a supplier datasheet? Yes, if you name the grade, link the source and label the figure as nominal. Recommend that buyers confirm values with batch documentation such as a mill test report before designing against them.

Should I declare which material is better? No. Write conditional recommendations ("choose A when...") tied to environment, load and cost drivers. That is more accurate and more useful to a buyer.

Do I need special markup to appear in AI answers? No. Google says AI Overviews and AI Mode have no additional requirements beyond normal search best practices, such as text content, internal links and structured data that matches the page.

Where should the quote request go? After the conditional recommendations, with a link to it from the opening summary, and listing exactly what information you need to quote.
