CuAg0,10

Silver is used as an alloy element to increase the resistance of the base material to the annealing, which enables greater thermal stability to be achieved of the products that make up the overhead power cable without sacrificing mechanical or electrical characteristics, and in consequence improve its durability.

Very high electrical conductivity, with significantly improved tempering properties as compared with highly conductive types of copper and improved flow properties at raised temperature. For commutator bars, collector rings and contacts.

The addition of silver to pure copper raises its softening temperature considerably with very little effect on electrical conductivity. Silver also improves the mechanical properties, especially the creep resistance. The 0.08-0.12% Ag grade gives very good resistance to creep and it is therefore suitable for use in highly stressed rotor winding strips.

Increasing additions of silver give increase in creep strength and resistance to softening in elevated service temperatures Good creep resistance to 250°C (short times at 350°C) provides suitability for electrical motor parts, semi-conductor components and etching plates.
