What are the Properties of Beryllium Copper?
Properties of BeCu:
Beryllium copper is a ductile, machinable, and weldable alloy.
BeCu has an excellent response to precipitation-hardening treatments.
BeCu has excellent thermal conductivity (62 Btu/ft-deg.F-H), and it is about 3-5 times more conducting than Tool steel.
It shows resistance to stress relaxation.
It is resistant to non-oxidizing acids such as hydrochloric acid (HCl) and carbonic acid (H2CO3), to plastic decomposition products, to abrasive wear, and galling.
It can be heat-treated for increased strength, durability, and electrical conductivity.
Beryllium copper displays the maximum strength (up to 1,400 MPa (200,000 psi)) of any copper-based alloy.
