C26000 Cartridge Brass (70Cu-30Zn)

C26000 Cartridge Brass, also known as 70/30 brass, is a copper-zinc alloy containing approximately 70% copper and 30% zinc. It is renowned for its excellent cold working properties, good corrosion resistance, and high ductility. Due to its outstanding formability and machinability, C26000 is one of the most widely used brass alloys in sheet, strip, and tube production.

Fabrication & Manufacturing of C26000 Brass

👉 These properties make C26000 a top choice for forged brass components that require both strength and ductility.

  • Cold Workability: Excellent (deep drawing, stamping, spinning)
  • Hot Forming: Good, typically forged at 700–800 °C
  • Machinability: Fair (rated ~30 compared to free-cutting brass = 100)
  • Joining: Excellent for soldering and brazing, fair for welding
  • Corrosion Resistance: Good in normal atmosphere, seawater, and industrial environments
