  • Bushings/Bearing for
  • Aerospace Industry
  • Aircraft Engine Parts
  • Propellers
  • Bolts And Cams.
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.

Available Status

Brush Name ASTM Name Description
A TB00 Solution annealing state (quenched state)
½H TD01 Quarter hard
½H TD02 Half hard (semi-hard)
¾H TD03 Three-quarters hard
H TD04 Hard state (full hard)
AT TF00 Standard aging heat treatment in quenched state
¼HT TH01 Quarter hard standard aging heat treatment
½HT TH02 Half-hard standard aging heat treatment
¾HT TH03 Three-quarters hard standard aging heat treatment
HT TH04 Hard standard aging heat treatment (a process of comprehensive strengthening of deformation and aging)
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).
