Introduction to Aluminum CNC Machining Very few substances can match the incredible versatility of aluminum. Aluminum is highly machinable and relatively inexpensive, making it perfect for CNC machining. Manufacturers can machine it three or even four times faster than other common machining materials such as steel and titanium.Get more news about aluminium cnc machining parts discount,you can vist our website! Its flexibility and impressive strength-to-weight ratio make it ideal for use as the exterior skin panels of all forms of transportation, from automobiles and trains to aircraft and boats. Greater emphasis on fuel efficiency and “lightweighting” has seen aluminum replace the heavier metals traditionally used to make components and internal structures. Its high corrosion resistance also avoids the need for heavy and expensive anti-corrosion coatings often required by other materials. Additionally, aluminum is non-toxic, malleable and 100% recyclable. This is why the metal is so widely used for food and drink containers, trays, lids, sachets, pouches and wrappers. Thanks to its sleek, silver surface finish, it is also well-suited for electronic devices like smartphones, laptops, tablets, and flatscreen TVs. It can even be found in construction projects both as a design feature and to provide structural support. Put all these characteristics together and you have a material that is lighter than steel, stronger and more reliable than plastic, inexpensive, readily available and infinitely adaptable. Where does aluminum come from? Aluminum is the most abundant metal element in the Earth’s crust. The metal industry smelts more than 40 million tons each year, and manufacturers use it in numerous applications. Like most metals, aluminum is present in rocks throughout the Earth’s crust as an ore. Mining companies extract almost all aluminum metal from bauxite ore, which typically contains 30% to 60% aluminum oxide (or alumina). The rest is a mixture of silica, various iron oxides and titanium dioxide.
