Types of Materials We Use for St. Charles, MO, Automotive CNC Manufacturing
In automotive manufacturing, material selection is key to ensuring the performance, safety, and longevity of vehicle components. At Roberson Machine Company, we leverage a diverse selection of metals and plastics, each chosen for its unique strengths—strength, weight, corrosion resistance, and machinability—to fulfill the precise needs of automotive applications. This includes:
- Aluminum (6061, 7075, 7050): Lightweight and corrosion-resistant, aluminum Alloys are commonly used for engine components, suspension parts, and housings. Higher-grade alloys like 7075 are often used for performance and motorsports.
- Stainless Steel (303, 304, 316, 321, 420SS, 416, 440): Valued for their strength and corrosion resistance, stainless steels are ideal for components like exhaust systems, fasteners, and drivetrain parts. Harder grades such as 440 are particularly known for their 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: Valued for its machinability and corrosion resistance, brass is ideal for manufacturing fittings, bushings, and valves used in fluid-handling systems and connectors.
- Titanium: Lightweight yet incredibly strong, titanium is used in high-performance applications where minimizing weight without sacrificing strength is essential, such as in exhaust systems and racing parts.
