Copper based wire electrode for wire electro-discharge machining |
摘要 |
A wire electrode for use in electro-discharge machining is formed essentially of Cu, including Zn of 5 through 38% by weight and Si of 0.1 through 0.5% by weight so as to suppress sputtering of the electrode material to the workpiece and to improve workability. The wire electrode may include Zn of 30 through 40% by weight, Si of 0.1 through 1.2% by weight and Al of 0.01 through 0.2% by weight in addition to Cu.
