IS 410 Standard – Wrought Brass Sheets & Strips

Common Brass Sheet Grades

CuZn30 (Cartridge Brass, IS 410, ASTM C26000)
  • ~70% Cu, 30% Zn
  • Excellent ductility, corrosion resistance.
  • Used in deep drawing (cartridge cases, lamp caps, utensils).
CuZn37 (IS 410, ASTM C26800)
  • ~63% Cu, 37% Zn
  • Higher strength, still good ductility.
  • Applications: Radiators, roofing, decorative panels.
CuZn40 (IS 410, ASTM C28000 – Muntz Metal)
  • ~60% Cu, 40% Zn
  • Stronger, less ductile.
  • Applications: Shipbuilding, condenser plates.

Special Brass Sheet Alloys

Admiralty Brass (CuZn29Sn1, ASTM C44300)
  • Cu ~70%, Zn ~29%, Sn ~1%
  • Excellent corrosion resistance (especially to seawater).
  • Applications: Heat exchangers, condensers, marine.
Naval Brass (CuZn40Sn1, ASTM C46400)
  • Cu ~60%, Zn ~39%, Sn ~1%
  • High strength, seawater resistance.
  • Applications: Marine fittings, propeller shafts.
High Tensile Brass (CuZn40Mn, ASTM C35600 / IS 313)
  • Cu ~60%, Zn ~40%, Mn traces
  • Extra strength, toughness.
  • Applications: Heavy-duty marine, defense, engineering parts.
