Also what are some intersting facts about Aluminum? (the element) thanks 2 any 1 who answers =)
Aluminum is a versatile material with vast applications in engineering, aerospace and automotive industries. Some of its desirable properties include lightweight (relative to steel) and high strength. The metal is however rarely used in its pure form, it is often alloyed with other elements such as Mg, Manganese, chromium, Titanium to fine tune its mechanical, chemical and or physical properties and tailor it to specific applications. However, in some applications other materials are preferred, for example, Magnesium, due to its higher strength to weight ratio is increasingly replacing Al in transmission casing of automobiles. Also, Compacted Graphite cast Iron is preferred in engine blocks because of its superior strength at high tempreatures, dimensional stability and wear resistance. Auto engines work at very tempreatures and alloys that are capable of withstanding high pressures while maintaining stability are critical. CGCI performs better than Al in this situation. Al alloys remains an important engineering materials though.
Corrosion resistance due to passivation and low density.
