Copper-Beryllium Age Hardening

Process to achieve maximum strength and electrical conductivities in copper alloys via precipitation of minute beryllium phases from the supersaturated solid solution.

Copper beryllium is hardened by precipitation hardening. When welding, you need to watch out to keep the heat input low, otherwise you lose the previous hardening. After welding, the material is usually solution annealed again and then controlled aged to get the desired strength. If you don't do that, the zone stays soft and can crack.
