Beryllium Cooper Connector Heat Treatment

1.Beryllium copper annealing refers to beryllium copper heat treatment process, which means that beryllium copper is slowly heated to a certain temperature, kept for a sufficient time, and then cooled at an appropriate rate.The purpose is to reduce hardness and improve machinability;Eliminate residual stress, stabilize size, reduce deformation and crack tendency;Refine grain, adjust structure and eliminate structure defects.To be precise, annealing is a heat treatment process for materials, including metallic and non-metallic materials.

2. What is beryllium copper?
Beryllium copper: Beryllium copper is a copper alloy with beryllium as the main alloy element, also known as beryllium bronze.It is the most advanced elastic material in copper alloy with high strength, elasticity, hardness, fatigue strength, small elastic hysteresis, corrosion resistance, abrasion resistance, cold resistance, high electrical conductivity, non-magnetic, impact without spark and a series of excellent physical, chemical and mechanical properties.Beryllium copper is – kind of supersaturated solid solution of copper base alloy, is the mechanical properties, physical properties, chemical properties and corrosion resistance good combination of nonferrous alloys, after solid solution and aging treatment, with special steel is quite high strength limit and elastic limit, yield limit and fatigue limit, and also has a high electrical conductivity, thermal conductivity, high hardness and wear resistance, high creep resistance and corrosion resistance, are widely used in the manufacture of various types of mold inserts, replace the steel production of high precision, complex shape of the mould, welding electrode materials, die-casting machine, punch machine, wear-resisting corrosion work, etc.Beryllium copper strip is used in micromotor brushes, mobile phones, batteries and products. It is an indispensable and important industrial material for national economic construction.

3. What are the annealing effects of beryllium copper?
(1) Reduce hardness and improve machinability.
(2) Eliminate residual stress, stabilize size, and reduce deformation and crack tendency;
(3) Refine grain, adjust structure and eliminate structure defects.
(4) Uniform material structure and composition, improve material performance or prepare for subsequent heat treatment.

4. Annealing process of beryllium bronze is as follows in SIMUWU model RVA-669 vacuum annealing furnace :
1) First clean the workpiece and then load it into the furnace.
2) Bake in an oven at 315 ° C for 2 hours, using an atmosphere of 4% hydrogenation and 96% nitrogen, with a minimum air pressure of 10Pa.
3) Cool the oven to below 95 degrees Celsius before opening the oven.
