- Great potential for surface finishing and anodization
What Types of Aluminum Are Used for CNC Machining?
On its own, aluminum is too weak for commercial use. So, to achieve strength, pure molten aluminum is combined with copper, lithium, magnesium, manganese, silicon, and zinc to form an alloy and enhance aluminum’s other properties.
Three common alloys are used in aluminum CNC machining: cast aluminum, aluminum lithium, and wrought aluminum alloys.
Cast Aluminum Alloy
Cast aluminum alloys are affordable, lightweight, versatile, and durable and perform well under high temperatures. This alloy is famously used in the automotive industry for engine parts, housing, steering columns, and structural support.
Cast aluminum alloys are inexpensive to produce because they possess a low melting point and can easily be shaped. However, it does have a lower tensile strength, is not as easy to machine, and is more hard-wearing on cutting tools.
Aluminum Lithium Alloy
The second aluminum alloy used for aluminum CNC machining is aluminum lithium alloy. This alloy is primarily used in aerospace manufacturing due to its lightweight nature, making it the prime choice for lower wing skins, inner wing structures, fuselages, and fan blades for aerial vehicles. Aluminum lithium alloys are also used for race cars and space rockets.
The downside to using aluminum lithium alloys for CNC machining is it does not have a high fracture toughness. This means that when this alloy is cracked, it becomes compromised and weak to resist further cracking. Aluminum lithium alloys are also more expensive compared to cast aluminum alloys.
Wrought Aluminum Alloy
The last but best aluminum alloy for CNC machining is wrought aluminum. Wrought alloys have superior mechanical properties and structural integrity compared to cast aluminum alloys. They are also easier to machine and make for better surface finishes since they are less hard-wearing on the edges of cutting tools.
