What Surface Finish Can Be Used For Aluminum Parts?

1.Sand blasting
Sand blasting is a process that using the impact of the high-speed sand flow to clear and coarsen the metal’s surface,which can improve the  mechanical property of the parts’ surface and Fatigue resistance.
2.Polishing
Polishing is a process that reducing the roughness of the parts’ surface to make the parts with bright and smooth appearance by the mechanical, chemical or electrochemistry.
The main polishing process is mechanical polishing,chemical polishing and electrolytic polishing.
The aluminum parts can be close to the mirror finish of the stainless steel after mechanical polishing and electrolytic polishing.
3.Wire drawing
Wire drawing is a metal working process used to reduce the cross section of wire by pulling it through a series of dies.
4.Anodizing
Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.Anodizing not only can solve the problems about the aluminum’s surface hardness and anti-abrasion,but also extend the service life of aluminum.
