Tungsten Copper Bar Picture
With the perfect arrangement of W and Cu, tungsten copper W75 rod provides a best way to solve the deformation in some small precision machining. And mixed with Fe properly, which tungsten copper can adsorb on magnetic workbench and it is convenient for grinding and cutting. Compared with other methods, its products have better roughness and size precision, especially in large flat electrode machining.
