Common Draw Materials Used in Our Deep Drawn Stampings
Posted on
At National Die Company, we have been specializing in precision deep drawn stampings for over 80 years. Our extensive experience has taught us that selecting the right materials is crucial; it's not something to guess at. We take material selection seriously as an essential part of our process.
Our customers across aerospace, medical, electronics, and defense industries count on us to deliver high-performance deep drawn stampings with consistency and accuracy. And we deliver by sticking with a core group of materials we know inside and out. These metals are proven to perform under pressure, form well, and meet the tight tolerances that deep drawing demands.
Here’s a look at the materials we work with every day and why they continue to earn our trust in the production of reliable deep drawn components.
300 & 400 Series Stainless Steel
Stainless steel is a workhorse in our facility. It's strong, corrosion-resistant, and highly formable, ideal for deep drawn stampings.
- 300 Series: Alloys like 304, 305, and 316 are known for their excellent corrosion resistance and non-magnetic properties. They're a top pick for medical components, food-grade equipment, and parts exposed to high humidity or chemical environments.
- 400 Series: These alloys offer good corrosion resistance, combined with higher strength and magnetic properties. They're widely used in automotive, appliance, and industrial applications where durability is key.
Stainless steel is ideal for precision deep drawn parts used in medical devices, military gear, and electronic enclosures.
Brass
Brass combines formability with visual appeal and excellent conductivity. It’s commonly used in electrical, plumbing, and decorative hardware, where both performance and appearance matter. Its machinability and corrosion resistance also make it a practical choice for components used in commercial and battery-powered systems.
Copper
For applications where electrical and thermal conductivity is critical, copper is unmatched. It's a preferred material for connectors, terminals, and deep drawn stampings in the electronics, telecommunications, and energy storage sectors. Copper's formability makes it ideal for intricate deep drawn designs, especially in electronics and battery housing.
Bronze
Bronze brings together strength, corrosion resistance, and wear resistance, making it well suited for long-life deep drawn components in aerospace and industrial applications. While it’s not as commonly used as brass or copper, it remains a solid option for components that need added durability and mechanical strength.
Aluminum
Aluminum is favored for its lightweight nature, corrosion resistance, and versatility. It’s often selected for deep drawn stampings in aerospace, automotive, and consumer electronics, where weight reduction and environmental resistance are crucial. Its adaptability across grades and finishes makes it a smart choice for a wide range of precision deep drawn components.
Low Carbon Steel
Low-carbon steel, also known as mild steel, is dependable, affordable, and easy to form. It's used in a broad range of commercial, automotive, and industrial applications. While it may require secondary treatment for corrosion resistance, its strength and ductility make it a reliable option for large-volume deep drawn stampings.
Why Material Selection Counts
The right material can make all the difference in the success of your deep drawn stamping project. It's not just about what the part looks like; it's about how it performs under real-world conditions. Whether it needs to withstand extreme temperatures in aerospace, deliver precise conductivity in electronics, or meet cleanroom standards in medical devices, we make sure the material is up to the task.
At National Die Company, our deep knowledge of these metals allows us to engineer high-quality deep drawn stampings that meet exacting requirements across multiple industries. By staying focused on proven materials, we eliminate surprises and deliver results to our customers.
