Selecting the right material is one of the most important decisions in manufacturing. It affects strength, weight, cost, corrosion resistance and long-term performance. When producing pressed components, understanding which metal to choose can significantly improve both quality and value.
In this guide, we explain the key factors to consider when choosing materials for metal pressings and how AEO helps customers make the right decision.
Why Material Choice Matters in Metal Pressings
Metal pressings rely on force, tooling and controlled deformation. Because of this, the chosen material must handle bending, forming and shaping without cracking or distortion.
The right material ensures:
Structural strength
Longevity
Cost-efficiency
Corrosion resistance
Repeatable quality
Compatibility with downstream processes like welding or coating
Choosing the wrong material can increase cost, reduce performance or create production challenges.
Common Materials Used in Metal Pressings
AEO works with a wide range of metals. Each one has unique properties and advantages.
1. Mild Steel (CR4, DC01, S275, S355)
Mild steel is one of the most common materials used in pressings.
Benefits of Mild Steel
✔ Easy to form
✔ Cost-effective
✔ Suitable for high-volume production
✔ Works well with most tooling
✔ Ideal for welding and fabrication
Best Applications
Brackets
Mounting plates
Automotive components
Structural parts
General manufacturing
Mild steel is the ideal choice when strength and affordability matter most.
2. Stainless Steel (304, 316, Ferritic Grades)
Stainless steel offers excellent corrosion resistance and is often chosen for harsh or demanding environments.
Benefits of Stainless Steel
✔ High corrosion resistance
✔ Strong and durable
✔ Food-safe and hygienic
✔ Good temperature performance
✔ Accurate forming when supported by the right tooling
Best Applications
Rail interiors
Energy sector hardware
Medical or food equipment
Outdoor components
Safety-critical parts
Stainless steel provides longevity but is more expensive than mild steel.
3. Aluminium (1050, 5251, 5083, 6082)
Aluminium is lightweight and easy to work with, making it popular where weight reduction is essential.
Benefits of Aluminium
✔ Lightweight
✔ Good corrosion resistance
✔ Good strength-to-weight ratio
✔ Easy to machine
✔ Excellent for prototypes and small batches
Best Applications
Electrical enclosures
Automotive lightweight components
Brackets and frames
HVAC systems
Renewable energy systems
Aluminium is versatile, but it can require careful tooling selection for deep forms.
How to Choose the Right Material
When selecting materials for metal pressings, consider the following factors:
1. Strength Requirements
Heavy-duty parts may require mild steel or stainless steel. Lightweight structural parts often benefit from aluminium.
2. Environmental Conditions
Outdoor, corrosive or high-temperature environments are better suited to stainless steel or coated steel.
3. Forming Requirements
Deep draws or tight bends require materials that can stretch without cracking.
4. Cost Targets
Mild steel is generally the most cost-effective option for high-volume production.
5. Weight Considerations
If weight reduction is important, aluminium is the clear choice.
6. Weldability
Some grades are easier to weld than others. AEO advises the best option based on your design.
7. Compatibility With Finishes
Zinc plating, powder coating or painting may influence your material choice.
