[China Aluminum Industry Network] (1) Strength and hardness are lower than that of copper, and the machinability is better. (2) The knife is easily sticked during the processing, and the cutter surface becomes rough. (3) The structure is not dense enough. Less roughness (4) Tool life is generally higher (5) Deformation is likely to occur during carding and machining, and the surface of the workpiece is easily scratched or scratched (6) The expansion coefficient is greater, affecting the dimensional accuracy .
