原文 :
EN55075:1991 Clause 15.3要求如下:
1. copper
2. an alloy containing at least 58% copper for parts made from rolled sheet or at lease 50% copper for other parts. Or
3. other metals having a mechanical strength, an electrical conductivity and a resistance to corrosion adequate for their intended use.
没有说一定要用铜或含铜的, 可以用other metals, 如铁吗?
