Is it okay to cut copper wire by wire cutting?
Any cutting injury conduction block, but the resulting in cutting aluminum alumina is a high hardness, poor conductive material, will be attached to the conductive block, influence the electrical properties, reduce processing efficiency, increase the wear of electrode wire and conductive block. When processing aluminum material, it is necessary to use oxalic acid to clean the conductive block for a period of time. It will improve the processing efficiency and protect the conductive block.
Because the center temperature of the wire cutting is very high, the aluminum will produce alumina at high temperature. The hardness of alumina is quite high. Will cut the pulley and conductive block of the machine tool. And cutting speed is not so fast.
Wire cutting can not cut pig iron because there are some non conductive impurities in pig iron. Copper and aluminum can be cut, but they hurt molybdenum wire and hurt the conductive block.
