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.
