The complete copper beryllium bar is hauled by a sling, placed on a special cutting table, and then cut by a cutting wheel saw. Each copper block with a length, height and width of 100cm×9.2cm×18.5cm is made, and the weight is about 130kg. Then, the uneven surface of the copper strip is polished and smoothed by the beryllium copper strip surface washing machine, which is beneficial to the flatness and smoothness of the surface of the beryllium copper strip processed in the later stage. At present, because the surface of the beryllium copper strips produced is not ideal, the thickness of 2 mm is removed on both sides. If the beryllium copper strips still have protrusions after washing the surface, they can be polished with a grinding wheel.
Production technology advantage
- All products of the company are made of high-quality new materials, advanced production equipment, and vacuum melting furnaces. The metal materials are smelted under vacuum conditions, which can achieve the effect of high-temperature smelting and avoid oxidation of metal and oxygen in the air. Function, quality is more guaranteed;
- 20MN double-action reverse extruder;
- Equipped with comprehensive testing equipment such as universal testing machine, direct reading spectrometer, etc., to strictly control the quality and inspect layer by layer.

Note: In the Brush name:
- "A" represents the state of solution annealing (annealed, the alloy is in the softest state, easy to be stamped and formed, and needs to be cold worked or strengthened during the direct failure period);
- "H" stands for cold processing state (hard);
- "T" means that the material has been aging hardened by standard heat treatment (heat treatment means the state of aging strengthening heat treatment).
