Aluminum is known for its lightness and flexibility. It can be cast, melted, molded, machined, and extruded, allowing it to be molded into a variety of shapes and then constructed to fit a variety of applications. Aluminum is becoming more popular due to its incredible adaptability and strength, as well as the numerous advantages it offers. Aluminum extrusion allows for increasingly complex designs to be produced. This extrusion can be machined or fabricated further and comes in a variety of finishes, including anodized, milled, and painted.
Aluminum is a versatile metal that has a lot of benefits. But some highlighted are: -
- Light Weight
It is a well-known lightweight metal with a specific weight of 2.71 g/cm3. It weighs about a third as much as steel, making it easier and less expensive to transport than most other metals. Aluminum strength may be tweaked by adding different alloying elements to achieve better results, such as increased strength or easier formability.
- Corrosion Resistance
Aluminum is a corrosion-resistant metal that produces a protective covering on its own. When aluminum comes into touch with an oxidizing atmosphere, a very thin coating is created. This protective layer of aluminum oxide helps to preserve the metal's surface against corrosion. Surface treatment such as painting or anodizing can also help to improve the metal's overall corrosion resistance.
- Electrical and Thermal Conductivity
Aluminum is a great heat and electrical conductor. Although it is not as conductive as copper, it is about a third of the weight, so an aluminum wire half the weight of a copper wire would have the same electrical resistance. As a result, it is the material of choice for high-voltage power transmission lines. It's also a good heat conductor, thus it's utilized as heatsinks in LED lights, electrical appliances, and computer motherboards, among other things.
- Reflectivity and Ductility
Aluminum also has the advantage of being a good reflector. Because of its capacity to reflect both light and heat, it is utilized in rescue blankets and light fittings.
- Odorless and Impermeable
Aluminum foil, even with a thickness of 0.007 mm, is impermeable and has no discernible taste or odor. This is a non-toxic material that is frequently used in the packaging of delicate products such as drugs and food.
Aluminum is 100% recyclable and retains all of its original qualities during the recycling process. It is more cost-effective to employ recycled metal during production than prime metal mined from the ground, thus as much recycled material as feasible is used.
