Copper & Brass

Electronics Applications, Among Others

Copper and Brass alloys are avialable in many tempers for a wide range of applications

  • 1/4 Hard - Easily formed with minimal spring characteristics.
  • 1/2 Hard - Easily formed with moderate spring characteristics.
  • 3/4 Hard - Good ductility with moderate to good spring characteristics.
  • Full Hard - Small radius bends, parallel with grain may fracture.  Good spring characteristics.
  • Spring Temper - Part designs should incorporate larger bend radii, especially when bends are parallel to grain.  Excellent spring characteristics.

C110 Copper

  • Automotive - gaskets, radiators
  • Electrical - bus bars, contacts, terminals
  • Forms well. - Temper determined by work hardening at the mill.  Can not be heat treated.
  • High cost - Piece prices may be effected by market fluctuations 

C172/Alloy 25 (Beryllium Copper)

  • Excellent for electronics applications.
  • Forms very well.
  • Stays stable in heat treating.
  • Many plating options.
  • Tempers:
    • A Soft (TB00) / Heat Treated after forming, TF00
    • 1/4 Hard (TD01) / Heat Treated after forming, TH01
    • 1/2 Hard (TD02) / Heat Treated after forming, TH02
    • Hard (TD04) / Heat Treated after forming, TH04
    • *All above tempers form very well and produce good to excellent spring characteristics after forming.
  • May be purchased in mill hardened conditions (TM00, TM01, TM02, TM04, TM05, TM06 and TM08).  These are not suitable for most formed shapes.

C260 Cartidge Brass

  • Automotive - radiator and heater cores
  • Electrical - contacts, terminals
  • Forms well - Temper determined by work hardening at the mill.  Can not be heat treated.

C510 Phosphorous Bronze

  • Springs and spring contacts
  • Temper determined by work hardening at the mill.  Can not be heat treated.
    • Forms well in softer tempers.
    • Small radius bends, especially when parallel with grain may fracture in harder tempers.
  • Many plating options.
