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.

FAQ:

Q1:What’s the advantages the Beryllium Copper of CUBERYLLIUM®?

A1: 1: The Biggest Coil weight could be reach 1200kg/Coil.

2:We are the only one who melting by Vacuum semi-Continuous Furnace.

3:Surface further polishing for top clients.

Q2: How about your payment terms?
A2: Generally, 30% as deposit by T/T, then 70% should be paid before the delivery.

Q3: Why you melting by Vacuum semi-Continuous Furnace?
A3:Could be get the Cast ingot without gas,smaller segregation, Grain Refinement

Q4: What's the payment terms?
A4: We accept T/T, L/C, Paypal etc. It can be negotiated when the amount is different.
