Sleeves/Shafts Typical application

  • Aluminum die casting industry
  • Plastic Molding industry

Wonder copper advantage:

  • Class 4 Alloy has extremely high hardness and ultimate tensile strength although the electrical conductivity is lower than the Class 3 Alloy
  • Class 4 Beryllium Copper (17200) is available in heat treatable tempers. Alloys are used in a wide range of applications requiring high strength and stiffness with good conductivity.
  • Typical uses include electrical/electronic connectors, current-carrying springs, precision screw machined parts, welding electrodes, bearings, plastic molds and corrosion resistant components.
  • Class 3 copper is specifically recommended for projection welding dies, flash and butt welding dies, current carrying shafts and bushings. Class 3 castings are recommended for welder components that carry current, and are under heavy load, including heavy duty offset electrode holders. Class 3 copper is generally recommended for spot welding and seam welding steels having high electrical resistance, such as stainless steels.

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).
