Copper Sheets

Oxygen-Containing Copper (ETP Copper)
  • C11000 (ETP – Electrolytic Tough Pitch Copper)
  • Purity: ≥ 99.90% Cu, Oxygen ~0.02–0.04%
  • Excellent electrical conductivity (~100% IACS).
  • IS Equivalent: IS 191 Part 1 – Cu-ETP
  • Applications: Electrical busbars, conductors, switchgear, panels.
Oxygen-Free Copper (OFC / OFHC)
  • C10100 (Oxygen-Free High Conductivity Copper)
  • Purity: ≥ 99.95% Cu, Oxygen ≤ 0.001%
  • Superior conductivity & corrosion resistance.
  • IS Equivalent: IS 191 Part 2 – Cu-OF
  • Applications: Electronics, vacuum tubes, superconductors.
Deoxidized Copper (Phosphorus-Deoxidized)
  • C12200 (Cu-DHP – Deoxidized High Phosphorus Copper)
  • Contains ~0.015–0.04% P.
  • Excellent corrosion resistance, weldability, not suitable for high-conductivity uses.
  • IS Equivalent: IS 191 Part 3 – Cu-DHP
  • Applications: Plumbing, roofing, chemical equipment, heat exchangers.
Copper Alloys, also widely used in India

Brass & Bronze Sheet Grades

Brass Sheets (Cu-Zn alloys)
  • IS 410 (CuZn30, CuZn37 – Cartridge brass, Muntz metal).
  • Applications: Decorative panels, automotive radiators, cartridge cases.
Phosphor Bronze Sheets (Cu-Sn-P alloys)
  • IS 7814 (CuSn5, CuSn8).
  • Applications: Bearings, springs, electrical connectors.
Aluminium Bronze Sheets (Cu-Al alloys)
  • IS 305 (CuAl10Fe3).
  • Applications: Marine hardware, pumps, aerospace.
