Copper Nickel Tin
Characteristics：
This alloy is a spinodal decomposition-strengthened copper material. Through cold working and aging treatments, it demonstrates excellent overall performance with high strength. Free of elements such as beryllium and lead, it serves as an effective alternative to beryllium copper. In addition, it offers non-magnetic properties as well as outstanding resistance to corrosion, wear, and heat.
Typical applications:
Suitable for wear-resistant and corrosion-resistant bushings.
