微量铜对球铁性能的影响

Effect of Trace Copper on Properties of Nodular Cast Iron

球墨铸铁中加入一定量的铜对性能进行调整是常用的方法,在加入比较小量的情况下,对球墨铸铁已有的力学性能和铸造性能没有影响,对局部性能有促进作用或稳定作用时,具有比较实用的意义。

Adding a certain amount of copper in nodular cast iron to adjust its performances is a common method. When the adding amount is smaller, it has not obvious effect on mechanical properties and casting properties of nodular cast iron,but has promoting and stable effect on local properties. It has practical significance.
