Cars and Transportation
Aircraft carriers have aluminum components. It is also used in boats and other sea faring vessels because it is light. Railway carriages also use it. Aluminum can be found on cars for aesthetic and thermal purposes. It’s cheaper than other metals so manufacturers prefer it.
Car parts like wheel spacer bars, transmission housings, hoods, suspension components and engine blocks are usually built of aluminum. The metal is also used in impellers, alternator housings, air filler adapters, mirrors and brackets. Car ornaments also rely on aluminum.
The element is vital to transportation because of its weight / strength ratio. Aluminum is light; in vehicles this translates to less energy required for motion. It isn’t as strong as steel. But it can be alloyed with other metals to increase its strength. The light weight means fuel efficiency. That’s why aluminum parts are common in trains, boats and cars. It is particularly essential in aircraft.
Aerospace
Aluminum has been used in the aerospace industry from the beginning. It was also a vital part of America's effort in World War 2. Most of America's fighter planes were made of this lightweight, cheap, and corrosion resistant material.
Aluminum's corrosion resistance and strength-to-weight ratio make it ideal for aircraft manufacturing.
Corrosion is a very dangerous and expensive problem, and aluminum can last for decades without any noticeable corrosion.
Steel is a very high-strength option, but its weight is prohibitive. It can adversely affect the aircraft's aerodynamics. For this reason it is only used in landing gear and other parts where its strength is necessary.
Aluminum helps keep their weight down. More than 75% of a plane’s unladen weight is comprised of aluminum. The metal is corrosion resistant, another important feature. Aluminum means painting is not needed. This means savings in money and weight.
Building Construction
In the early 20th century aluminium was used mostly for roofing, wall panels, and flashing. As the century marched on it became used for more structural purposes.
New York's Empire State Building marks one of the first extensive use of aluminum in a building's construction. The spire, structure, entrances, elevator doors, decorative trim, and window panels all contain aluminium.
As we move forward, aging concrete and steel structures will need to be reinforced or replaced. Aluminum's durability and cost-effectiveness make it a prime candidate to fix the decaying materials.
Food Service
Aluminum is extensively used in food service. Though it is second to stainless steel in popularity, it is difficult to walk into a modern, commercial, kitchen without seeing many appliances and utensils that are made from aluminum.
Part of aluminium allure in the food service industry is is rust resistance. Its chemical makeup makes rust virtually impossible. Their versatility is another selling point for aluminum kitchen ware.
Aluminum is a good conductor of heat so it can reach a desired temperature quickly and stay that way for longer. This makes it ideal to wrap leftovers or serve anything from piping hot to frosty.
Sporting Goods
Sporting goods utilize anodized aluminum. Anodizing is a process that gives a metal a durable, corrosion resistant, finish that can be decorated. Aluminum's unique properties make it ideal for the process, though other non-ferrous metals are also good candidates.
