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.
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.
