    • EN DIN: European norms for aluminum bronze alloys.
    • JIS (Japan): Standards for copper alloy sheets and plates.
    • GB/T (China): National standards for industrial copper products .

Chemical Composition (Weight Percentage)

C61400 is an aluminum bronze alloy with the following typical composition according to ASTM standards (e.g., ASTM B150/B150M-2012) :

ElementMinimum (%)Maximum (%)Notes
Copper (Cu) + Silver (Ag)88.092.5Base metal, provides ductility and electrical conductivity
Aluminum (Al)6.08.0Enhances strength and corrosion resistance
Iron (Fe)1.53.5Improves hardness and wear resistance
Manganese (Mn)-1.0Aids in deoxidation and grain refinement
Zinc (Zn)-0.20Limited to avoid adverse effects on corrosion resistance
Lead (Pb)-0.01Strictly controlled for purity
Phosphorus (P)-0.015Minimized to prevent brittleness
Silicon (Si)-0.10Trace amounts (if present)

Key Notes:

  • The high aluminum content (6–8%) distinguishes it as a aluminum bronze, not a nickel-based alloy . Earlier references mentioning high nickel (12–18% Ni) likely conflated C61400 with other copper-nickel alloys .
  • Strict limits on impurities (Pb, P) ensure optimal mechanical and corrosion-resistant properties .
