   | CuAg0,04 OF EN: CW017A, CR017A UNS: C10400, C10500 |    |
Excellent consistency, machinability and cleanliness of strips enable good stamping behaviors. Commutator strips and wires offer higher softening temperature and improved properties. 
Increasing addition of silver give increase in creep strength and resistance to softening in elevated service temperatures. Good creep resistance to 250°C (short times at350°C) provides suitability for electrical motor parts, semi-conductor components and etching plates.
The addition of silver increases the resistance to recrystallization up to 450°C and improves creep properties up to 250 °C. The resistance to recrystallization and creep increases with increasing silver content.
The oxygen-free quality is maintained throughout the casting process without the addition of deoxidising elements. With a maximum impurity content of 65 ppm, CuAg0,04OF meets the enhanced requirements for electronic applications. The quality is free of oxygen and so insensitive to hydrogen embrittlement. The quality is also free of phosphorous and so provides an excellent and reliable electrical conductivity.
Oxygen-free copper grade containing silver, resistance to hydrogen embrittlement, increased resistance to softening with high conductivity.
