C17300 Leaded Beryllium Copper (CDA 173)

Wire in coils available in continuous length or small coils

This alloy is an age-hardened alloy having developed higher strengths while maintaining acceptable levels of toughness for many industrial applications. The age-hardening response of this alloy depends on the factors of time, temperature, and cold work applied to the metal. Toughness, fatigue strength, corrosion resistance, etc., can be modified and controlled by either under-aging or over-aging during the precipitation hardening process of the alloy.
