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, Alloy 25) 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 (C17500, Alloy 10) Alloy is generally recommended for spot welding and seam welding steels having high electrical resistance, such as stainless steels. The Class 3 Alloy is heat treatable.

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).
