Types of Materials We Use for Charlotte, NC, Automotive CNC Manufacturing
Material selection is fundamental in automotive manufacturing, directly impacting the performance, safety, and lifespan of vehicle components. At Roberson Machine Company, we carefully choose from a variety of metals and plastics, each selected for its optimal characteristics—strength, weight, corrosion resistance, and machinability—to meet the demanding requirements of automotive applications. This includes:
- Aluminum (6061, 7075, 7050): Known for being both lightweight and resistant to corrosion, aluminum alloys are ideal for engine parts, suspension components, and housings. For high-performance uses, alloys like 7075 are the go-to choice, especially in motorsports.
- Stainless Steel (303, 304, 316, 321, 420SS, 416, 440): Renowned for its strength and corrosion resistance, stainless steels are essential in applications ranging from exhaust systems to fasteners and drivetrain components. Hardened grades like 440 are particularly effective in providing wear resistance.
- Plastics (Delrin, PETGs, Nylon, PLAs, PEEK, HDPE, Glass-Filled Nylon): These materials are ideal for lightweight, non-structural parts such as bushings, gears, and interior components. Certain types, like PEEK, are resistant to high heat and chemicals.
- Brass: Known for its excellent machinability and corrosion resistance, brass is commonly used for fittings, bushings, and valves in fluid-handling systems and connectors.
- Titanium: Titanium’s combination of low weight and high strength makes it ideal for performance applications requiring a strong strength-to-weight ratio, including exhaust systems and racing components.
