Choosing the right material is one of the most critical decisions in any metal stamping project. The material affects part strength, corrosion resistance, formability, surface finish, and ultimately — cost. At Metal Stamp Factory Co., Ltd. in Xiamen, China, we work with a wide range of metals to meet the diverse requirements of our global OEM clients. This guide covers the top 5 materials used in metal stamping and helps you choose the right one for your application.
1.Stainless Steel (SUS301 / SUS304)
Stainless steel is one of the most widely used materials in precision metal stamping. At Metal Stamp Factory Co., Ltd., SUS304 is our most frequently processed grade, used extensively in products like stainless steel bird spikes, construction hardware, and industrial components.
Key properties:
- Excellent corrosion resistance
- High tensile strength
- Smooth, burr-free surface after stamping
- Suitable for outdoor and food-grade applications
- Material thickness: 0.3mm – 3.0mm
Common applications: bird control products, kitchen equipment, outdoor hardware, medical devices, and marine components.
2.Cold Rolled Steel (SPCC
Cold rolled steel (SPCC) is the most cost-effective and commonly used material in high-volume metal stamping. Its excellent formability and consistent surface quality make it ideal for structural and industrial parts.
Key properties:
- Excellent formability and ductility
- Consistent thickness and surface quality
- Lower cost compared to stainless steel
- Easy to weld, paint, and coat
- Material thickness: 0.3mm – 6.0mm
Common applications: automotive brackets, construction hardware, electrical enclosures, furniture hardware, and industrial equipment components.
Metal Stamp Factory Co., Ltd. processes large volumes of SPCC coil stock daily using progressive die stamping using our YAMAZK SPP-110 and SPP-80 stamping presses.
3.Galvanized Steel (SGCC)
Galvanized steel is cold rolled steel with a protective zinc coating applied to both surfaces. The zinc layer provides outstanding corrosion protection, making it the preferred choice for outdoor and weathering applications.
Key properties:
- Zinc-coated surface for corrosion protection
- Good formability
- Cost-effective for outdoor applications
- Suitable for powder coating and painting
- Material thickness: 0.3mm – 3.0mm
Common applications: solar mounting brackets, roofing hardware, HVAC components, agricultural equipment, and outdoor construction hardware.
For solar mounting system manufacturers, galvanized steel (SGCC) is one of the most requested materials at Metal Stamp Factory Co., Ltd., particularly for racking components and mounting brackets.
4.Aluminum Alloy (A1050 / A3003 / A5052)
Aluminum alloys are increasingly popular in metal stamping due to their excellent strength-to-weight ratio. Aluminum is approximately one-third the weight of steel, making it ideal for applications where weight reduction is critical.
Key properties:
- Lightweight — 1/3 the weight of steel
- Good corrosion resistance
- Excellent thermal and electrical conductivity
- Easy to anodize and surface treat
- Material thickness: 0.3mm – 4.0mm
Common applications: solar panel frames, electronic enclosures, automotive components, heat sinks, and aerospace hardware.
Common grades processed at Metal Stamp Factory Co., Ltd.:
- A1050 — pure aluminum, highest conductivity
- A3003 — good formability, moderate strength
- A5052 — highest strength among non-heat-treatable alloys
5.Copper and Brass (C1100 / H62)
Copper and brass are essential materials for electrical and electronic applications due to their outstanding electrical conductivity. While more expensive than steel, they are irreplaceable in applications requiring reliable electrical performance.
Key properties:
- Excellent electrical and thermal conductivity
- High ductility for complex forming
- Natural antimicrobial properties
- Available in various alloy grades
- Material thickness: 0.2mm – 3.0mm
Common applications: electrical terminals, connectors, relay components, battery contacts, and precision electronic parts.
Material Comparison at a Glance
The chart above summarizes the key properties and typical applications for each of the five most common metal stamping materials. When selecting a material for your project, consider the operating environment, required strength, surface finish requirements, and budget.
How to Choose the Right Material
When selecting a material for your metal stamping project, Metal Stamp Factory Co., Ltd. recommends considering these key factors:
- Operating environment — Will the part be used outdoors or in a corrosive environment? Choose stainless steel or galvanized steel.
- Weight requirements — Does the application require lightweight parts? Choose aluminum alloy.
- Electrical performance — Does the part need to conduct electricity? Choose copper or brass.
- Production volume — High-volume orders benefit from cold rolled steel (SPCC) for its low cost per unit.
- Surface treatment — Will the part be painted, plated, or anodized? Different materials respond differently to surface treatments.
