Foshan Nanhai Yinan Non-ferrous Metal Profile Plant is the first professional manufacturer EDM zinc coated wire in China. Patent number is 200520061757.8.
The superiority of the EDM zinc coated wire is as follow.
1、Cutting speed of ZH-20、ZH-25 is 10%-15% faster than EDM brass wire，stable conductivity，hard to break.
2、Improving workpieces surface roughness，no copper powder，processing the hardness of the workpieces，extending mould service life.
3、Processing precision is rather better than EDM brass wire.
4、Save consumable.
