Aluminumis a lightweight, non-magnetic, silver-colored metal that can be formed into almost any shape. It can be rolled into thick plates for armored tanks or thin foil for wrappers. It can also be drawn into wire and made into cans.
Pure aluminum is soft and has limited strength. Small amounts of elements such as copper, magnesium and/or zinc are added to increase strength.
Aluminum is the third most abundant element in the earth’s crust after oxygen and silicon and is a comparatively new industrial metal that has been produced in commercial quantities for just over 100 years.
- Can produce parts of almost any shape
- Cost-effective for prototyping and short runs
- High dimensional tolerances are possible
- Smooth finishes can be achieved
- Avoid flimsy shapes
- Use shapes that will hold well during machining, like straight edges
- Milling creates a visible cut pattern on the surface of the material
- Avoid deep pockets and ensure corners are rounded
Aluminum is a popular choice for many metal products and components:
Has good mechanical properties and good weldability, and is one of the most common alloys for general purpose use – especially for machining.
Widely used for construction of aircraft structures, such as wings and fuselages, yacht construction, utility boats and bicycle frames and components.
One of the most popular aluminum alloys used in sheet metal fabrication. It is readily bent, punched and sheared.
Known for its high corrosion resistance, especially in ocean water. Common applications include marine and aircraft equipment, fuel lines, street lights, household appliances, flooring panels, and railings.
Used in applications requiring high strength to weight ratio, and has good fatigue resistance. It is not weldable and has average machinability.
Corrosion resistance is poor. Widely used in aircraft structures, especially wing and fuselage structures under tension.
Has generally good mechanical properties, and is heat treatable. Highly weldable although strength near welds can be diminished by up to 30% if not subsequently heat treated.
Mostly used in extruded shapes for architecture, including window frames, door frames, roofs, piping, tubing and furniture.
Strong, with good fatigue strength and average machinability, but is not weldable and has limited resistance to corrosion.
Cost is relatively high compared to other Aluminum alloys. Often used in aircraft including wings and fuselages, rock climbing equipment and bicycle components.
