Metal Forming Industries has the proven capability to provide its customers with components manufactured from a variety of different materials. Since 1999, MFI has developed specialty cold forming, impact extrusion, and precision machining processes in copper, aluminum, and brass materials.
MFI process engineering can provide specific material recommendations based on a detailed review of the customer designed part application.
Brass in Cold Forming and Impact Extrusion
Brass is an alloy of copper and zinc, and it offers a unique combination of strength, corrosion resistance, and machinability. Brass is commonly used for both cold forming and impact extrusion, especially in applications where appearance, durability, and ease of machining are important.
Cold Forming with Brass
Brass is often used for creating components such as plumbing fittings, electrical connectors, and decorative hardware. Its excellent machinability, corrosion resistance, and aesthetic appeal make it a popular choice in the cold forming process.
Advantages of Brass in Cold Forming:
- Corrosion Resistance: Brass’s resistance to corrosion, especially in marine and plumbing applications, makes it ideal for parts that will be exposed to moisture and harsh environments.
- Machinability: Brass is easy to machine, allowing for precise and detailed parts to be formed quickly and efficiently.
- Aesthetic Appeal: Brass has an attractive golden appearance, making it a popular material for decorative components such as hardware, jewelry, and coins.
Common Brass Alloys Used in Cold Forming:
- Leaded Brass: Contains a small amount of lead, which improves machinability and is often used in the production of parts like screws, fasteners, and plumbing fittings.
- Forging Brass: Offers excellent strength and corrosion resistance, making it suitable for structural components and fittings.
Impact Extrusion with Brass
Brass is also a preferred material for impact extrusion, especially for producing parts that require high corrosion resistance and a smooth surface finish. Brass impact-extruded components are commonly used in plumbing, electrical, and automotive applications.
Advantages of Brass in Impact Extrusion:
- Formability: Brass’s good malleability and ductility make it ideal for impact extrusion, where intricate shapes and hollow sections are required.
- Durability: Brass’s corrosion resistance ensures that parts will maintain their structural integrity and appearance over time, even in challenging environments.
By selecting the appropriate material for cold forming and impact extrusion, manufacturers can create high-quality, durable parts that meet the specific requirements of their applications. Whether for lightweight automotive components, high-performance electrical connectors, or corrosion-resistant plumbing fittings, these metals continue to play a vital role in modern manufacturing.
