  • 4140 steel alloy CNC machining metal material — high-strength, durable metal for precision CNC machined components.

    Steel Alloy 4140

    Impact Resistance, Fatigue Resistant

    AISI 4140 Alloy Steel is a medium-carbon chromium-molybdenum steel with a carbon content of about 0.38–0.43%. It offers an excellent combination of strength, toughness, wear resistance, and machinability. When heat-treated, it provides outstanding mechanical properties, making it widely used in gears, crankshafts, connecting rods, bolts, and critical components in the oil and gas industry.

  • Brass rod and sheet samples

    Brass C260

    CorrosionResistant, Machinability

    Brass is an alloy primarily composed of copper and zinc. This golden-hued material not only exhibits excellent weather resistance and corrosion resistance, but its tensile strength also rivals that of low-carbon steel, demonstrating outstanding mechanical properties. Brass boasts exceptional machinability, enabling it to support higher feed rates during processing operations such as cutting and stamping, while requiring minimal cutting fluid. This combination significantly reduces both processing costs and process complexity.
