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.

Key Technology of Beryllium Copper(Heat treatment)
Age Hardening
Age hardening significantly enhances the material’s strength. This
reaction is generally carried out at temperatures between 260°C and
540°C depending on alloy and desired characteristics. This cycle
causes the dissolved beryllium to precipitate as a beryllium rich
(gamma) phase in the matrix and at the grain boundaries. It is the
formation of this precipitate which causes the large increase in
material strength. The level of mechanical properties attained is
determined by the temperature and time at temperature. It should be
recognized that beryllium copper has no room temperature aging
characteristics.
