UNS C17200 beryllium copper alloys are ductile and produced in mill hardened and heat treatable tempers. These alloys are used for all applications, which require high strength, stiffness and good conductivity. The tensile strength of C17200 copper is over 1380 MPa (200 ksi).
1. High load capacity Good anti-wearing
2. Low coefficients of friction
3. Good heat conductivity
4. High corrosion resistence
5. Long life and maintenance-free
6. No contaminant by oil or grease
