Each material gives special features to the alloy casting so that the resulting has desired properties. The percentage compositions of these materials greatly affect the final alloy properties. Aluminum casting alloy rims are produced through the use of low-pressure die casting. This method is used due to its many advantages. Some of the advantages of this process include design versatility, high dimensional accuracy, good surface quality, low equipment & dies cost, high productivity, good mechanical strength, and its economic nature.
