Tier 4-5 · materials, castings & forgings
Marketing for Tier 4 and Tier 5 suppliers: foundries, forges, mills and service centers
Marketing for foundries, forges, mills and service centers starts with the grade. You make materials and semi-finished forms. Tier 2-3 buyers place the order, but an OEM materials engineer named the grade and the standard on the drawing first. We build grade and size pages both of them can check before they call.
Won on Vocabulary
How do foundries, forges and service centers reach new buyers?
They publish what a buyer has to match: the grades they pour, forge or stock, called out by AMS, ASTM or ASME standard; the size and weight ranges; the certs and traceability that ship with every lot; and what is on the shelf today. A buyer holding a drawing can then check the fit without a phone call.
Where you sit on the ladder
Tier 4 and Tier 5 suppliers sit at the base of the ladder. Your buyers are Tier 2 and Tier 3 shops and the distributors that stock for them. Where Tier 4 ends and Tier 5 begins varies by industry; most charts put semi-finished forms such as castings and forgings above the raw materials they are made from. The same shop is Tier 3 to an aerospace Tier 1 and Tier 1 to a machine builder. Pick the rung you want more of.
-
Step 1, OP 10
Your buyer: Tier 2-3 suppliers (OEM engineers specify)
Buyers order by grade; OEM materials engineers name the standard.
-
Step 2, OP 20
You: Tier 4-5
Materials, castings, forgings, bar, plate, wire, resins and powders.
-
Step 3, OP 30
Your suppliers: Raw inputs
Ore, scrap, feedstock.
What they check
Buyers and materials engineers check six things before they ask for a quote.
-
Step 1, OP 10
Grades
Which AMS, ASTM or ASME grades you pour, forge, draw or stock, listed by standard.
-
Step 2, OP 20
Size ranges
Weights, diameters, thicknesses and lengths, smallest to largest.
-
Step 3, OP 30
MTRs and traceability
Mill test reports with every lot, and how heat numbers follow the material.
-
Step 4, OP 40
Melt source
Where defense buyers ask about domestic or specialty-metals sourcing, your answer stated plainly.
-
Step 5, OP 50
Stock and minimums
What ships from stock, the minimum order, and lead time on mill or foundry orders.
-
Step 6, OP 60
Value-add
Cutting, machining, heat treat, testing and inspection before it ships.
What Tier 4-5 sites say vs what wins
These are illustrative patterns.
| What sites usually say | What wins | |
|---|---|---|
| Grades | 'All common alloys' | One page per grade family, with standards called out |
| Sizes | 'Call for availability' | Size and weight ranges in HTML tables |
| Process | 'Quality castings' | Sand, investment or die casting, with tolerance and finish by process |
| Certs | A logo | MTRs and traceability explained |
| Stock | 'Large inventory' | Forms and sizes on the shelf, by grade |
At this rung
Four kinds of company, each with its own checks.
-
Castings & foundries
Process, alloys, weight range.
-
Forgings
Open-die, closed-die, rolled rings.
-
Mills & service centers
Grades, forms and processing.
-
Resins & powders
Grades, data sheets, lot control.
Castings & foundries
Castings and foundries
Casting buyers check the process first, then the alloy and the weight range. Say which processes you run (sand, investment, die or permanent mold), the alloys you pour, the smallest and largest part, the tolerance and surface finish each process holds, and the machining and testing you do before shipping. Add a tooling page that says who builds the patterns and who owns them.
Example: Basalt Ridge Castings (invented, basaltridge.test) gives investment and sand casting their own pages, each with alloy families, weight range and the inspection methods it offers.
Forgings
Forgings
Forging buyers check the method, the grade and the envelope. Separate open-die, closed-die and rolled-ring work, because buyers search for each by name. For each one, list the grades, the size and weight limits, the heat treat and testing you offer, and whether parts ship rough or machined.
Example: Anvil Point Forge (invented, anvilpoint.test) lists rolled rings by diameter and face height, and closed-die parts by weight and grade, for aerospace and oil and gas buyers.
Mills & service centers
Mills and service centers
Mills and service centers are checked on grades, forms and processing. List every grade and form you carry (bar, plate, sheet, tube, wire), the size ranges, and the processing you add, such as saw cutting, plasma or waterjet cutting, and heat treat. Buyers want to know what ships today, so say how stock is shown and how a cut-to-size order is quoted.
Examples: Hemlock Bar & Plate (invented, hemlockbar.test) has a page per grade family with size tables and cut-to-size limits. Cinder Mill Wire (invented, cindermill.test) lists fine-wire diameters and tempers for medical and electronics buyers.
Resins & powders
Resins and powders
Resin and powder makers are checked on grade data and lot control. Put each grade's data sheet on the page as HTML, with the test standard behind each property, and explain how lots are controlled and certified. For metal powders, add particle size range, chemistry and the processes each powder is made for.
Examples: Seastone Compounds (invented, seastone.test) publishes engineered resin grades for medical and consumer molders. Graywacke Powders (invented, graywacke.test) lists metal powders for additive manufacturing by alloy and size range.
Who holds the results page today
Material searches are often held by distributors, directories and marketplaces. A grade page with the size range, standards and certs in HTML can take a place among them, and it gives AI assistants a maker's own answer to repeat. Start with the searches nobody holds yet.

What IKE maps for you here
IKE, our Industrial Knowledge Engine, maps your grades and forms to the standards that call for them, and to the parts and markets that use them. It learns your company, then your competitors, then your markets. SiteSonar, always on, names the companies reading your grade pages.
What IKE learns is manufacturing. Your record stays yours.
What your Blueprint captures here
The paid Buyers Blueprint captures every grade, form, size range, cert and value-add service, so a buyer can check you before they call. We draw on your website, data sheets, team meetings and an on-site visit, and confirm every fact with you before it is published.
Short stories for materials suppliers
Each takes a few minutes and ends with three checks you can run on your own site.

Questions
Is there a Tier 4 or Tier 5 supplier?
Yes. Below Tier 3 sit the companies that supply materials and semi-finished forms: castings, forgings, bar, plate, wire, resins and powders.
We sell to distributors, not shops. Does this fit?
Yes. Distributors are buyers too, and their customers check your grade data before they order.
Why put data sheets on the page as well as in PDFs?
Search engines and AI assistants can read an HTML table, and an engineer can scan it without a download. Keep the PDF beside it for anyone who wants the file.
Should we publish our stock?
Publish what a buyer needs to decide whether to call: the grades and forms you carry and the size ranges. Live quantities can stay behind a quote request.
