Types of Materials We Use for Providence, RI, Automotive CNC Manufacturing
Material selection is pivotal in automotive manufacturing, directly influencing the performance, safety, and longevity of vehicle components. At Roberson Machine Company, we leverage a diverse array of metals and plastics, each chosen for its unique properties—strength, weight, corrosion resistance, and machinability—to meet the specific demands of automotive applications. This includes:
- Aluminum (6061, 7075, 7050): Aluminum alloys are lightweight and resistant to corrosion, making them an excellent choice for engine components, suspension parts, and housings. High-strength alloys like 7075 are often used in performance and motorsports applications for their durability.
- Stainless Steel (303, 304, 316, 321, 420SS, 416, 440): Known for their durability and resistance to corrosion, stainless steels are widely used in applications such as exhaust systems, fasteners, and drivetrain components. Hardened varieties like 440 offer outstanding 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: Due to its superior machinability and corrosion resistance, brass is commonly found in fittings, bushings, and valves within fluid 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.
