FEATURES OF CuSn12Ni2 TIN BRONZE / EN 1982 CC484K

The load characteristics of the worm wheel depend on the sliding speed.c=200-1250N/cm2 or short-time load 4000-4500N/cm2. It is a high strength alloy with good abrasion resistance and corrosion resistance in sea water. The addition of nickel increases durability and corrosion resistance. Outstanding characteristics of CuSn12Ni2 Tin Bronze / EN 1982 CC484K are as follows:

1. Chemical composition:

- Copper (Cu): Makes up the majority, plays the main role in the structure of the alloy.

- Tin (Sn): Provides hardness and dimensional stability.

- Nickel (Ni): Enhances hardness and corrosion resistance.

- Phosphorus (P): May be present to improve machinability.

2. Hardness and Ductility: CuSn12Ni2 Tin Bronze  typically has good hardness and moderate ductility, making it suitable for many applications.

3. Corrosion resistance: The incorporation of CuSn12Ni2 Tin Bronze  can improve its corrosion resistance.
