镍是工业上用途很广的一种贵金属,在零件或金属制品上镀上镍层以后,十分光亮美观,具有防护和装饰性的作用。由于我国镍的资源较少,所以研究和试用其他金属来代替镍,具有很大的经济意义。高锡青铜是目前得到实际应用的代镍镀层之一。
Nickel is a precious metal that is widely used in industry. It is very bright and beautiful after being coated with a nickel layer on parts or metal products, and it has the function of protection and decoration. Due to the limited resources of nickel in our country, it is of great economic significance to study and test other metals instead of nickel. High-tin bronze is currently one of the practical substitutes for nickel plating.
