Technical specifications

  1. Hardness of the alloy: HB 10−1 = 130 — 150 MPa
  2. Melting point: 995 ° C

The BrB2 alloy has excellent spring properties in the quenched state, it does not contain deficient tin in its composition, but in its consumer qualities it often surpasses other non-ferrous alloys. Beryllium bronze is produced in accordance with GOST 18175−78. This standard applies to bronze bronze, which are processed under pressure and are designed for the production of sheet and long products.
