AXSR Copper Alloy Material Technology Group is an invisible champion enterprise in the field of high-performance electrical contact materials and products in China.
The company has 9 product divisions:
●Medium voltage vacuum copper-chromium series contact material division
The medium voltage vacuum copper-chromium series contact material division specializes in the production of CuCr10-CuCr50 (containing Cr10%-50%) series of contact materials, which have excellent vacuum breaking and pressure resistance capabilities. It is widely used in the contact material of vacuum interrupter for vacuum circuit breakers of 126kV and below. It is currently the main contact material used in vacuum interrupter. The company currently has four production lines of vacuum infiltration, vacuum casting, vacuum arc melting, and powder mixing sintering. There are more than 100 vacuum sintering and smelting equipments. The company has the ability to produce 8 million pieces of CuCr contacts of various specifications. The world’s largest manufacturing base for vacuum contact materials.
●Medium and high voltage tungsten copper series contact material division
The medium and high voltage tungsten copper series contact material division specializes in the production of copper-tungsten alloy materials, which have high voltage resistance and arc ablation resistance. It is widely used in various switch arc contacts, and is currently the most widely used contact material in various switches. The company has built production lines for producing copper-tungsten contact materials by means of vacuum infiltration, atmosphere protection infiltration, friction welding, electron beam welding, etc., and has the ability to provide 200,000 pieces of various copper and tungsten products to the market every year.
●Electromechanical Division-High conductivity, high strength, high temperature resistant copper alloy materials and products
The main products of the Electrical and Mechanical Division are high-conductivity, high-strength, high-temperature resistant copper alloy materials, such as end rings, guide bars, shrink rings for high-speed railway motors and subways, and slot wedges, hollow conductors and damping parts for large generators. . Mainly used in high-speed railways, subways, oil and gas and wind power generation.
●Copper Busbar division
The copper busbar business unit is based on the fact that the company is the only domestic copper alloy company that has passed the rail transit IRIS certification. This business unit provides special-shaped copper busbars and flexible connections for rail transit locomotives to European and American foreign companies.
●High temperature alloy precision turbine disc division
In response to the domestic and foreign markets’ demands for high-precision precision machining of high-power diesel locomotives, gas turbines, and aero-engine superalloy turbine disks, the company introduced the world’s most advanced five-axis turning-milling composite machining center and two high-speed horizontal machining centers of 6 meters and 4.5 meters. The side broaching machine has built a high-temperature alloy turbine disc precision processing production line, which is the only private enterprise in China, and has supplied products to the domestic and international high-end markets in batches.
●Medical Products Division
Based on the company’s technical reserves and advantages in vacuum smelting copper alloy materials, at the request of Siemens Medical Business Department, we developed special performance copper alloy materials (copper nickel 44 manganese) and vacuum welding components for medical CT equipment X-ray tubes for them. And expanded to support this product for several well-known domestic and foreign enterprises.
The business unit has supplied various special copper alloy products with independent intellectual property rights to domestic and foreign customers in batches, contributing to the localization of key materials and components for national medical equipment.
●Metal Chrome Division
The company has a unique ultra-low temperature (minus 196 degrees) production line for preparing high-quality low-oxygen metal chromium powder in China, which is one of the core technologies for the performance and quality assurance of copper-chromium series contact materials and chromium-zirconium-copper alloy materials.
In addition to satisfying the company’s use of high-quality chromium powder, it also supplies high-quality chromium powder to Siemens, GE and other European and American companies.
Based on more than 20 years of technological precipitation in metal chromium treatment, the future will provide strong technical support for the development of high-end national nickel-based and chromium-based superalloys.
●High Voltage Products Division
The high-voltage products division specializes in the production of copper-chromium (VI), tungsten-copper (SF6) and chromium-zirconium-copper series electrical alloy materials, sputtering targets for vacuum coating, and electrode products for automotive welding.
At present, the company has formed four major technical systems: melting casting, infiltration, cold and hot extrusion, and precision casting, which support the production and development of different products.
●Advanced Copper Alloy Material Preparation Division
The Advanced Copper Alloy Material Preparation Division mainly produces chromium-zirconium-copper alloy bars, wires, wires, other special alloys, master alloy materials and special-shaped casting products. Currently, it has multiple vacuum induction melting furnaces, non-vacuum intermediate frequency induction furnaces, forging, Machining and other equipment, the annual production of copper materials and products exceeds 3000T. With the development of the project, it has successfully developed CuNi2Si series alloys, CuAlNi series alloys, CuFeP alloys and other materials, and produced copper-magnesium, copper-chromium, copper-zirconium and other intermediate alloy materials. It is widely used in electric power, electrical, rail transit, automobile, magnetic materials and other industries.
