Copper alloy castings (brass castings) have the highest corrosion resistance as well as mechanical properties of all die-cast parts. Owing to the high metal temperatures as well as shorter mold life, brass in die casting has not been accepted readily as a good alloy. Of the die-cast brass alloys, the yellow brasses are subjected to the metallurgical process the most often. The benefits of brass casting parts, as with other alloys used in die casting, comprise good surface finish, accurate dimensional control, as well as high production rates.
In brass die casting, the induction brass melting is preferred usually. It will create less melt loss via dross formation, quicker melting, better brass composition control and temperature control, and less absorption of gas by the metal. The brass melting process’s speed is also significant, to reduce volatile alloying elements’ vaporization. It pertains especially to zinc, one of the alloying elements of brass
