Beryllium copper vacuum heat treatment

Beryllium copper is a copper alloy with ruthenium as the main alloying element, also known as beryllium bronze.


It is the best high-grade elastic material in copper alloys, with high strength, elasticity, hardness, fatigue strength, small elasticity lag, corrosion resistance, wear resistance, cold resistance, high conductivity, non-magnetic, impact does not produce sparks, etc. a series of excellent physical, chemical and mechanical properties.


Beryllium copper is divided into processed bronze and cast bronze.


The commonly used processed beryllium bronzes include Cu-2Be-0.3Ni and Cu-1.9Be-0.3Ni-0.2Ti.


Beryllium bronze is a heat-treated strengthening alloy.

Processed beryllium bronze is mainly used as a variety of advanced elastic components, especially various components that require good conductive properties, corrosion resistance, wear resistance, cold resistance, and no magnetism, and are used in large quantities as bellows, diaphragms, bellows, and microswitches, etc.


Casting bronze is used for explosion-proof tools, various molds, bearings, bearings, bushings, gears, and various electrodes.


Beryllium copper is a supersaturated solid solution copper-based alloy. It is a non-ferrous alloy with good combination of mechanical properties, physical properties, chemical properties and corrosion resistance. After solid solution and aging treatment, it has high strength limit, elastic limit, yield limit and fatigue limit equivalent to special steel. At the same time, it also possesses high electrical conductivity, thermal conductivity, high hardness and wear resistance, high creep resistance and corrosion resistance, and is widely used in the manufacture of various types of mold inserts to replace steel molds with high precision and complex shapes, welding electrode materials, die-casting machines, punches for injection molding machines, wear-resisting and anti-corrosion work. Beryllium copper strip is applied to micro-motor brushes, mobile phones, batteries, and products, and is an indispensable important industrial material for national economic construction.
