Cuivre (Cu)89.0 – 91.0
Étain (Sn)9.0 – 11.0
Other Impurities (e.g., lead, iron)<0.2

Why Copper and Tin?

Combining copper and tin creates an alloy with unique qualities:

  • Cuivre (Cu) brings conductivity, flexibility, and resistance to corrosion.
  • Étain (Sn) enhances strength, wear resistance, and machinability.

Together, they produce a material that’s tough, yet workable – ideal for high-stress parts.

Characteristics of CuSn10 Powder

Solidité et durabilité

CuSn10 powder is known for its excellent tensile strength, making it an ideal candidate for applications that demand durability. Components made from CuSn10 can withstand high levels of mechanical stress, offering long-lasting performance even under intense conditions.
