Application

1W3, 3W3 generally used as embedded block for flash welding and butt welding, which has higher requirement of conductivity and malleability. These materials can also be used for welding (as a spherical electrode) for low-conductivity ferrous metals such as stainless steel;
5W3, TC5 is suitable for light projection welding and other low-pressure welding;
10W3 is suitable for most of flash welding, light electric upsetting, electric forging die, and seam welding inserts;
TC10 used for mass production of solder bumps where the weld pressure is set relatively high. Non-ferrous metal processing and low carbon steel electric forging rough This material is commonly used as a stamped surface, cross-welding large diameter wire and bar;
TC20 is extremely hard and hard to be machining, which has been widely used in electric upsetting and electroforming.
