C17300 Beryllium Copper Coil & Strip
Short Description:
In terms of composition, C7300 is almost similar to C17200, except that a small amount of lead is added to C7300 to increase cutting performance. C173 beryllium copper is also commonly referred to as M25 alloy. It is often obtained by precipitation aging heat treatment to obtain the corresponding strength. Commonly used in RWMA (Resistance Welding Manufacturing Alliance) aerospace, petroleum, marine, electronics, racing and plastic mold applications. In particular, circular socket connectors, sensors, non-sparking tools, welding equipment, flexible metal hoses, bushings, electrochemical springs and bellows.
