Beryllium bronze alloy has no change in strength and elongation, so it can be maintained in water for more than 40 years. beryllium copper alloy is an irreplaceable material for submarine cable repeater structures.
In sulfuric acid medium: the annual corrosion depth of beryllium bronze in sulfuric acid (room temperature) with a concentration of less than 80% is 0.0012-0.1175mm; if the concentration is greater than 80%, the corrosion is slightly accelerated, abrasion resistance, low temperature resistance, non-magnetic, high conductivity , Impact without sparks and other characteristics. It also has good fluidity and the ability to reproduce fine patterns. Because of the many superior properties of beryllium copper alloy, it has been widely used in manufacturing.
Use a vacuum heat treatment furnace to heat the supersaturated workpiece to a lower aging temperature (340 plus or minus 5 ° C). Because the supersaturated state is unstable, the extra beryllium atom diffuses and precipitates for a short distance. After holding for 2-3 hours, the precipitated Excess beryllium and copper will reach equilibrium, and the mechanical properties will be significantly improved at this time.
