Trial production method of cylinder head by joining low melting point aluminum alloy layer

摘要

The present invention relates to a method of manufacturing a prototype of an aluminum cylinder head by joining a plurality of divided members to each other, thereby shortening the joining process and time of the divided cylinder head, facilitating the prototyping process, . To this end, the present invention is characterized in that a Cu powder is applied to the joint surface of each member 5, and the coated surface is locally heat treated to form a low melting point alloy (Al-Cu) And then joining the aluminum alloy layer with the low melting point aluminum alloy layer in a heating furnace to provide a prototype method of the cylinder head.
