Beryllium bronze is a copper-based alloy containing beryllium (Be0.2-2.75% wt%). It is the most widely used of all beryllium alloys. Its amount has exceeded 70% of the total consumption of beryllium in the world today.
Beryllium bronze is a precipitation hardening alloy. After solution aging treatment, it has high strength, hardness, elastic limit and fatigue limit, small elastic hysteresis, and has corrosion resistance, wear resistance, low temperature resistance, non-magnetic, high electrical conductivity, No spark and other characteristics.
Corrosion resistance of beryllium bronze alloy in seawater: (1.1-1.4) × 10-2mm / year. Corrosion depth: (10.9-13.8) × 10-3mm / year. ) After corrosion, the strength and elongation of the beryllium bronze alloy have not changed, so it can be maintained in the water for more than 40 years. The beryllium copper alloy is an irreplaceable material for the submarine cable repeater structure.
