Material Selection Backed by Engineering Insight

The success of any stamped component starts with the right material. Stewart EFI brings decades of experience in deep draw, progressive die, and slide forming stamping to help you choose metals and alloys that perform under real-world conditions. Our engineers evaluate strength, durability, and manufacturability to ensure every component meets functional and environmental requirements while optimizing cost and production efficiency.

Materials That Handle Complexity and Tight Tolerances

The Stewart EFI team works with a broad spectrum of metals, alloys, and specialty materials, providing flexibility for standard and highly engineered components. We primarily operate in a material thickness range of .002 to .120 inches (0.05mm to 3.00mm), giving us the precision to produce components with tight tolerances and complex geometries. Materials include:

Standard & Common Alloys

Low and high carbon CR steel
Stainless steels:
302, 304, 304L, 305, 316, 410, 430, 435, 17-7PH
Copper, silver, beryllium copper, nickel alloys
Aluminum:
3003, 3005, 6061, 5657
Zinc, gold alloys, brazing materials

Exotic & Specialty Materials

Inconel, titanium, niobium, tantalum
High-performance plastics and composites
Kovar, Invar, 42 Alloy, 46 Alloy
Pre-treated or engineered materials:
pre-plated, pre-anodized, pre-heat treated, inlayed, skived, clad, painted
