A layer of non-metallic zinc phosphate is produced on the surface of the wire after treatment, which is helpful to the lubrication of the cold plastic processing of the wire. The use method is the impregnation method, which has the following effect and is beneficial to the drawing deformation.

1, Reduce friction between metal and metal;

2, Increase the life of the use of the mold;

3, Allowing faster drawing speed and greater deformation;

4, Reduce the breakage of the processed products;

5. A smooth and homogeneous surface can be made for the finished wire.
