With a copper content of at least 99.95% and low oxygen and phosphorous content, the SE-Cu58 alloy is better quality than the generally used copper types, E-Cu (UNS C11000) and SF-Cu (UNS C12200).
This material is used in general electrical engineering for cable straps and connectors, transformer coils, semiconductors and sheet metal parts (e.g. for seals).
heat sinks, heat exchangers and vacuum technology
Copper is generally not suitable for springs.
At high demands on the purity of copper we suggest the alloy OFE-Copper (UNS
C10100) with a copper content of minimum 99.99%.
