It can be divided into processing beryllium bronze and forging beryllium bronze. Commonly used forged beryllium bronze are copper-2Be-0.5Co-0.3Si, copper-2.6Be-0.5Co-0.3Si, copper-0.5Be-2.5Co, etc. The content of beryllium in processed beryllium bronze can be controlled as follows: 0.3% nickel or 0.3% cobalt in domestic beryllium bronze. The commonly used processing beryllium bronze are: Cu-2Be-0.3Ni, Cu-1.9Be-0.3Ni-0.2Ti, etc. Beryllium bronze is a heat treatment strengthening alloy. Processing beryllium bronze is important as a variety of high-grade elastic components, especially those requiring superior conductive properties, corrosion resistance, wear resistance, cold resistance, non-magnetic components. It is widely used as diaphragm box, diaphragm, bellows, micro-switches and so on. Forged beryllium bronze is used for explosion-proof objects, various dies, bearings, bushes, bushes, gears and various electrodes. Beryllium oxides and dust are harmless to human body. We should pay attention to their protection in production and application.

Beryllium copper is a kind of alloy with superior mechanical, physical and chemical properties. After quenching and tempering, it has high strength, elasticity, wear resistance, fatigue resistance and heat resistance. At the same time, beryllium copper has high conductivity, thermal conductivity, cold resistance and non-magnetism. It has no spark when bumping, is easy to weld and braze, and has excellent corrosion resistance in atmosphere, salt water and fresh water. The corrosion resistance rate of beryllium-copper alloy in fresh water is (1.1-1.4)*10-2 mm/year. Depth of decay: (10.9-13.8)*10-3 mm/year.

After decomposition, the strength and elongation rate have no change, so it can be maintained in the water for more than 40 years, which is the substitution data of submarine cable repeater structure. In sulfuric acid medium, the annual decay depth is 0.0012-0.1175 mm in sulfuric acid with concentration less than 80%, and the decay rate is slightly accelerated when the concentration is more than 80%. Beryllium copper is a supersaturated solid solution copper-based alloy. It is a non-ferrous alloy with excellent mechanical, physical, chemical and corrosion resistance. After solid solution and aging treatment, it has high strength limit, elastic limit, obey limit and fatigue limit, as well as high electrical conductivity, thermal conductivity, high hardness and wear resistance, and high creep resistance. And corrosion resistance, commonly used in the manufacture of various die inserts, instead of steel manufacturing precision, complex shape of the mold, welding electrode information, die-casting machine, injection machine punch, wear and corrosion resistance work.

Beryllium copper strip is used in brushes, mobile phones, batteries and products of micro-motors. It is an important industrial data that is lacking in the construction of civil economy. Density 8.3g/cm hardness (> 36-42HRC conductivity (> 18%) IACS tensile strength (> 1000mPa thermal conductivity (> 105w/m.k20 C) high-quality beryllium-copper important embracing non-ferrous metal high pressure, gravity forging die application of various working conditions, through in-depth study of beryllium bronze die data effective reason, composition and content of corrosion resistance of liquid metal, open up a dry line of high conductivity (heat), high strength and wear resistance. The data of beryllium bronze mould with high properties including high pressure, high temperature resistance, high toughness and corrosion resistance in liquid metal have handled the difficulties of non-ferrous metal forging die cracking and wearing in the sea, which has obviously improved die life, demoulding rate and casting strength, overcome the sticking and corrosive mould of liquid metal slag, improved the external quality of casting, reduced the cost of production, and reduced the die strength. The life is close to the entrance. Pine fir has high hardness HRC 43, density 8.3g/cm3 and beryllium content 1.9%-2.15%. It is widely used for inner inserts, core, die-casting punch, hot runner cooling system, heat conduction nozzle, integral cavity of blow moulds, automotive moulds, abrasive plates of plastic injection moulds.
