About
Hite Special Alloy is a high-tech enterprise, mainly engaged in the production of Hastelloy, Monel, Inconel, nickel and other high-temperature alloys.
C276 is an alloy of copper and tin, belonging to a low melting point and high hardness metal. It has good wear resistance, corrosion resistance, and impact resistance, but is easy to oxidize. Mainly used in manufacturing mechanical parts such as bearings, gears, shaft sleeves, and hardware products such as valves.
