Machining Cold Processed Products

In metallurgy, cold working refers to the processing of metal deformation at a temperature lower than the recrystallization temperature, such as cold rolling, cold drawing, cold forging, stamping, cold extrusion, and the like. The cold working deformation resistance is large, and the hardness and strength of the workpiece can be improved by work hardening while forming the metal.
Advantages of cold working:
1. The desired shape can be obtained while strengthening the metal;
2. Good dimensional tolerance and surface roughness can be obtained;
3. cheaper;
4. Some metals can only be subjected to a limited degree of cold working because they exhibit brittleness at room temperature;
5. Cold working impairs ductility, electrical conductivity and corrosion resistance. However, the degree of electrical conductivity reduction due to cold working is less than that of other intensive processing, so cold working is also used to strengthen conductive materials such as copper wire;
6. If the anisotropic properties and residual stress are properly controlled, they also bring benefits. If not properly controlled, material performance will be greatly impaired;
7. Since the effect of cold working can be reduced or even disappeared at high temperatures, cold work strengthening is not applicable for parts working in high temperature environments.
