Aluminum and Aluminum Alloys
Aluminum, also known as aluminium, is a lightweight, malleable metal that is commonly used in a variety of construction and industrial applications. Aluminum is strong and corrosion-resistant, lightweight and relatively easy to work with and form into various shapes. Because of its resistance to corrosion, aluminum is often used in outdoor and coastal applications where it may be exposed to harsh elements.
Aluminum is a versatile metal and can be alloyed with other metals such as copper, zinc, manganese, or magnesium to create a variety of commercial aluminum alloys. These alloys are used to improve the strength and formability of aluminum, allowing it to be used in a variety of applications where strength and durability are of paramount importance.
Aluminum alloys are classified into two main groups: wrought alloys and casting alloys. Wrought aluminum alloys contain between 0.2 -3% alloying elements and can be forged, extruded, rolled, or drawn into sheets, bars, wires, and tubing. Commonly used wrought alloys include 6061, 6063, and 7075, but there are many more available depending on the desired end-use application.
Casting aluminum alloys are those that are heated and poured into a mold to create a desired shape or form. They contain between 3-12% alloying elements and can be heat-treated to further improve the strength and hardness of the alloy. Common casting alloys include 356, A356, A357, C355, and 712.
Aluminum and aluminum alloys have some common uses, including:
- Automotive, aerospace and transportation parts
- Food and beverage cans
- Electrical components
- Appliances
- Structural members
- Building and construction materials
- Anodizing and surface treatments
Aluminum and aluminum alloys are an excellent choice for a variety of applications because they are lightweight, durable, and easy to work with. In addition, they are corrosion resistant, making them ideal for outdoor and coastal applications, and can be heat-treated and alloyed to provide additional strength, hardness, and formability depending on the end-use application.
