It can be divided into processing beryllium bronze and forging beryllium bronze. Commonly used forged beryllium bronze, etc. The beryllium content of processed beryllium bronze is controlled at 2% below. The domestic beryllium bronze is added 0.3% nickel or 0.3% cobalt. The commonly used processing beryllium bronze are: etc. Beryllium bronze is a heat treatment strengthening alloy. Processing beryllium bronze is important for all kinds of high-grade elastic components, especially for those components that require superior conductive efficiency, corrosion resistance, wear resistance, cold resistance, non-magnetic. Many of them are used as diaphragm box, diaphragm, bellows, micro-switches and so on. Forged beryllium bronze is used for explosion-proof equipment, various dies, bearings, bushes, bushes, gears and electrodes. Beryllium oxide and dust are harmless to human body, so they should be protected steadily in production and utilization. Beryllium copper is a kind of alloy with superior mechanical, physical and chemical functions. After quenching and tempering, it has high strength, elasticity, wear resistance, wear resistance, wear resistance and heat resistance. It also has high conductivity, thermal conductivity, cold resistance and non-magnetism. It has no spark when colliding, 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. Corrosion depth: (10.9-13.8)*10-3 mm/year. After corrosion, the strength and elongation remain unchanged, so it can be maintained in water for more than 40 years, which is irreplaceable data for submarine cable repeater layout. In sulphuric acid medium, the annual corrosion depth is 0.0012-0.1175mm in sulphuric acid with a concentration of less than 80%, and slightly accelerates when the concentration is more than 80%.
