Product Normal Description:

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.
