General InfoThe aluminum industries inception in the late 19th century brought about many changes in the metal industry and everyday life. At first aluminum was most often used for utensils and small ornamental objects. This showed the vast versatility and everyday usefulness of the metal to the entire world. This quickly moved into the industrial sectors and today aluminum is used in almost every imaginable application. Aluminum has an unbeatable strength to weight ratio that perfectly suits it to a wide range of uses. For transportation and aerospace it has allowed many progressions that would not have been possible with only steel. It has also been found to provide twice the conductivity of copper while weighting less and therefore requiring less expensive support structures to hold the lines over long runs. This is why aluminum wire is used for high power / high voltage lines throughout the world. Aluminum also forms it's own corrosion resistant film or barrier oxide layer which gives it anti-corrosion properties. This means that aluminum which is not mixed with high amounts of steel will not rust like other metals. This along with it's light weight and many casting options make it perfectly suited for garden statues and outdoor furniture. Aluminum is the 3rd most abundant element of the Earth's crust and is also the most reflective material when fully polished. Aluminum is one of the few metals the can effectively be used in all know metal casting processes. Die casting is used almost twice as much as any other technique. Die casting is a simple, inexpensive, versatile and the oldest way to form repeatable objects from aluminum. Sand casting is also widely used as virtually any pattern or shape can be pressed into the sand to form the mold into which molten aluminum can be poured and allowed to cool.
