铜在现代工业中的运用是非常广泛的。每年有50％的铜被电解提纯,用于电气工业,所以称铜是电气工业的“主角”是完全正确的。铜也是人类很早就发现并应用的古老元素之一。铜的冶炼至少已有5000年的历史了。斑烂多彩的铜合金铸造了人类绚丽的文明史。
The use of copper in modern industry is very extensive. Every year 50% of the copper is electrolytically purified for the electrical industry, so it is entirely correct that copper is the “protagonist” of the electrical industry. Copper is also one of the ancient elements discovered and applied by mankind long ago. Smelting of copper has been at least 5,000 years old. Colorful colorful copper alloy cast a brilliant history of civilization.
