W20-a type is a thickening type, which is applicable to aluminum material whose thickness is not more than 13 millimeter. W-20b type is for the small size (diameter greater than 6mm) of the aluminum; W-B75 type is for brass material, the W-BB75 type is of copper material and W-B92 type is of mild steel.
