Aluminum offers consumers the perfect combination of strength and durability. Although this lightweight material is not ordinarily recognized for its strength, aluminum can be mixed with certain alloys and tempered in order to increase its overall tensile strength. Aluminum becomes the superior choice in certain environmental situations and has one of the lowest densities available among commercial metals. In fact, it has a density that is one third of copper or steel. At low temperatures, steel is known to become brittle, whereas aluminum will exhibit an increase in strength.
