摘要

Process for the casting of valves in aluminum alloy, with the incorporation in the process of other metals that have to form the subsequently machinable parts, essentially characterized in that the casting areas are placed or reinforcement rings in brass, bronze or steel, which have to be incorporated into the valves, the male is then placed in the mold and the aluminum alloy poured, which, when cooled, will keep incorporated, forming an intimate body with the casting, to those areas that are not affected by the temperature of fusion, due to its higher index.
