ASTM B283/B283M-24

This specification establishes the requirements for **copper and copper die forgings produced by hot pressing method**.

The forgings included here are designated with the following Copper or Copper Alloy UNS Nos.:

  • C11000 (copper)
  • C14500 (copper-tellurium alloy)
  • C14700 (copper-sulfur alloy)
  • C36500 (leaded Muntz metal)
  • C37000 (free-cutting Muntz metal)
  • C37700 (forging brass)
  • C46400 (naval brass)
  • C48200 (medium leaded naval brass)
  • C48500 (leaded naval brass)
  • C61900 (aluminum bronze)
  • C62300 (9% aluminum bronze)
  • C63000 and C63200 (aluminum-nickel bronze)
  • C64200 (aluminum-silicon bronze)
  • C64210 (6.7% aluminum-silicon bronze)
  • C65500 (high-silicon bronze)
  • C67500 (manganese bronze)
  • C67600
  • C69300 (copper-zinc-silicon alloy)
  • C70620 (90% copper-10% nickel alloy)
  • C71520 (70% copper-30% nickel alloy)
  • C77400 (45% nickel-10% silver alloy)

The materials for manufacture shall be rods, billets, or blanks of such purity and soundness as to be suitable for processing by hot pressing.

Products shall be tested to examine their conformance to mechanical (tensile and yield strengths, and elongation), dimensional, and chemical composition requirements.

1.1 This specification covers the requirements for copper and copper alloy die forgings produced by the hot pressing method. The following copper and copper alloys are included:
