Choosing the right cast aluminum and aluminum alloys from among the hundreds of different grades and the many tempers in each grade requires understanding of the materials' designation system to know their compositions, tempers and properties.
Superhard finishing tools may benefit machined parts via finer surface finishes, greater wear resistance and harder, stronger microstructures. Also, some of the tools can last longer than their conventional counterparts.
