Due to the lack of density in aluminum, the energy output for machiningis fairly low compared to machining other materials. If your machine has weightrestrictions, using aluminum parts may prove to be beneficial due to its low densityand light weight. Aluminum also has excellent corrosion resistance, and is easy towork with heavy machinery due to its thermal and electrical conductivity. Becauseof its lightweight and general availability, aluminum is fairly inexpensivecompared to other metals.
