C1100 Copper Strip Manufacture International Standards

What is C1100 Copper strip?

C1100 copper strip is a strip or sheet in coil, roll product with a minimum copper content of 99.9%. Thanks to its high copper purity, C1100 copper exhibits superior electrical and thermal conductivity and excellent corrosion resistance. These properties make it an ideal material for electrical applications and various uses across industrial and residential sectors.

Alloy grade: C1100 according to JIS (Japanese Industrial Standards).
International standard: ASTM C1100.
Form and specifications:
- Strip form:
  - Thickness: 0.2 – 10 mm.
  - Width: 6 – 450 mm.
Equivalent copper grades:
- T11050 (ISC – CN)
- T2 (GB – CN)
- ECu-57 (DIN – GE)
- Cu-FRHC (NF – FR)
- М1 (GOST – RU)
