Composition

The chemical composition of Nickel Alloy K500 ensures optimal performance:

Controlling the ratio of nickel to copper within narrow limits and limiting impurities ensures the excellent corrosion resistance, workability, and weldability of K500 alloy.

The high nickel content gives the outstanding corrosion resistance in many environments including acidic, caustic and chloride solutions. Copper provides strength and hardness while allowing complex shapes to be formed and welded. Iron improves high temperature strength and hardness. Minimal carbon content reduces precipitation of graphite. Tight control of sulfur enhances corrosion resistance.
