The casting alloy is not stable and entrained in gas; The density of aluminum castings is lower than that of cast iron and cast steel, but the specific strength is higher. Casting crack: nonferrous casting parts Manufactures It is a crack formed at a higher temperature. Do not mix organic impurities in the molding sand to reduce the amount of air generated by the modeling materials; Heat exchange equipment used in chemical production, as well as parts that require excellent thermal conductivity on power machinery, such as cylinder heads and pistons of internal combustion engines, are also suitable for aluminum alloys.
After this plan, I combined the theory learned with production practice, trained myself to analyze and solve problems, and laid a solid foundation for future homework and study. If [...]
