Steel, stainless, iron, nickel and aluminum alloy castings to ASTM specification, cast through the Kormax foundry network for the US.
The alloy decides most of what a casting can do in service: its strength and toughness, its wear and corrosion resistance, and how it welds and machines. Small additions to a base metal such as iron, nickel or aluminum change each of these, and they change how the metal fills and feeds a mold.
Melting point, solidification behavior and fluidity also narrow which casting process suits an alloy, so the alloy and the process are chosen together. Kormax metallurgists review every enquiry for alloy and process fit before it is quoted.
This page groups the casting alloys by family and lists the grades cast most often, by industry.
Each foundry in the Kormax foundry network is vetted for capacity, material capability and process reliability. The foundry is chosen for the part, and repeat parts can be dual-sourced where supply security matters.
Green sand, no-bake and shell mold sand casting, plus investment casting. The process is recommended on finished-part cost, not on one foundry’s capacity.
Carbon and low-alloy steel, stainless and duplex, ductile, gray and white iron, manganese steel, nickel alloys and aluminum. The upper limit depends on the casting process.
Castings supplied by Kormax can be machined before delivery, so the part arrives ready to fit rather than routed to a second shop.
Tooling, samples, production, inspection and freight are managed end to end, with consignment and buffer stock available for repeat parts.
Kormax operates a management system certified to ISO 9001, ISO 14001 and ISO 45001. Independent third-party inspection is standard, and material certificates and inspection reports ship with every order.
These are the grades cast most often, grouped by the industries that specify them and the parts each is cast as. A grade not listed here is often still in range; the specification settles it.
Ductile iron, carbon steel to ASTM A216 WCB, and CF8M and CF3M stainless, cast as casings, impellers, wear plates, valve bodies and manifold blocks for pump, valve and hydraulic equipment builders, then machined and pressure-tested to drawing.
Corrosion-resistant stainless for wetted parts and ductile iron for housings and covers, cast for the OEMs that build municipal and industrial water equipment: pump volutes and impellers, valve and hydrant bodies, screen and aeration frames, and gearbox and drive housings.
Manganese steel to ASTM A128, white and Ni-hard irons, and high-chrome grades where abrasion, not load, sets part life. Cast as mantles and bowl liners, jaw and cheek plates, pump wet ends, and chute and feeder components for crushers, screens, mills and conveyors.
Ductile iron and low-alloy steel to ASTM A148 Gr 105-85 for structural and hydraulic castings: cylinder end caps, pivot and linkage housings, axle and transmission components, and counterweights for earthmoving and forestry machinery, cast and machined to the build schedule.
Carbon steel to ASTM A216 WCB, low-alloy grades for elevated temperature, and duplex and super-duplex stainless for sour and produced-water service, cast as valve and pump bodies, compressor and turbine housings, heat exchanger components and other pressure-containing parts.
Gray and ductile iron, carbon and low-alloy steel, and stainless grades for rail, material handling, compressor, gearbox and general industrial components. Contract machine shops and equipment builders source castings through Kormax to keep their machining capacity full, supplied raw or machined to print.
A new casting follows seven steps, from the first project meeting to delivery, and the drawing and specification agreed at the start are what every part is inspected against. The casting processes themselves are compared on the casting services page.
Part, specification and volumes reviewed at an initial project meeting.
Project plan set and engineering team briefed.
Design optimizations for casting agreed with the customer’s engineers.
Casting method, tooling and pricing options presented.
Iterations until all design and quality requirements are met.
Final drawing signed off and contract details agreed.
Production run and delivery to the agreed dates.
Castings supplied through Kormax go to industries where parts must meet strict tolerances and specifications, including aerospace, military and government applications. Four points set out how the supply is managed.
Dual-sourced foundries, consignment and buffer stock, and scheduled supply programs for repeat parts.
PPAP-based development and quality procedures from design review to production.
Parts are tendered across the foundry network, with low-cost tooling options and no hidden surcharges.
Every enquiry is checked by Kormax metallurgists for alloy and process fit before it is quoted.

Kormax went above and beyond to expedite 5 x units in a quick turnaround. The quality of the bronze and cast iron casting, machining, and service I would recommend to anyone. Looking forward to our next casting project
Kormax has exceeded our expectations for our Casting supply. They have helped enhance our product design, assisted with metallurgy and have offered fast and professional service. We wouldn’t have a doubt recommending them to any serious casting buyer.
They not only know their products but also understand the application of them, which is vital to ensuring our customers are delighted with the beautifully crafted pieces we deliver.
Kormax is great to deal with, good with their communications and never leaves us in the lurch. I would be happy to recommend Kormax.
Dealing with Kormax since late this year has been a pleasure. Good service, advice, and competitive pricing. Staff are a pleasure to deal with. Courteous, helpful, and obliging.
Kormax casts steel, stainless, iron, nickel and aluminum alloys to order for the US. Send the drawing or 3D model, the alloy and the annual volume to request a quote.
