Post treatment for aluminum and brass casting

Post treatments are gradually coming important for metal casting industry. Many mechanical or chemical properties should be improved or adjusted by post treatments. Post treatments can be divided into different types according to their function or process. For example, there are several surface treatments available for aluminum and brass casting parts such as anodizing, electroplating, powder coating, and painting. All these surface treatments can sever both as a decoration means and a corrosion resistance means. Such treatments only affect the surface structure of the casting parts while there are other post treatments which affect the inner structure of the casting parts like heat treatment, impregnation. Heat treatment can improve the hardness and roughness of the casting parts, and the impregnation can heal the inner pores of castings.
