Aluminum Precision Machining

Key Features of Aluminum

Aluminum is a metallic material that comes in silver or matte gray. The latter usually depends on surface roughness. Although it is relatively soft, it is very durable. One of the main reasons why aluminum is used in different industries is its light weight, good formability and ductility. Plus, it doesn't create magnetic issues and is non-flammable. Other relevant attributes we should mention include but are not limited to:

Its melting point is 640 degrees.

It has a density of 2.68 g/cm3.

It's strong enough that after repeated annealing, you can roll it into thin foil.

It has excellent thermal and electrical conductivity.

It has strong corrosion resistance.

It is ideal for working in sub-zero temperatures, where its strength increases.

Aluminum alloys, on the other hand, have some disadvantages that must be considered. These disadvantages are:

Depending on the cross section of the wire, copper may be a better conductor of heat and electricity.

They are sensitive to high temperatures of 200 to 250°C (392 to 482°F) and may lose strength.

Of particular concern when machining aluminum alloys is the interaction between the tool and the workpiece. In some cases, this interaction can lead to flank wear that can affect final shape and dimensional accuracy and the integrity of the workpiece surface. Additionally, cutting forces in aluminum alloy machining should be kept low compared to those used on ferrous alloys. This is because aluminum alloys have low mechanical strength. The 70% reduction in cutting force may result in lower specific cutting pressures than steel machining, maintaining material integrity. However, this difference is usually not significant from one aluminum alloy to another, and the decision to vary cutting forces will depend on the physical and chemical properties of the particular alloy. Obviously, this requires very specialized knowledge to do correctly.
