The Best Aluminum Alloys for Machining

The Best Aluminum Alloys for Machining Posted on July 30, 2019

Any metal’s machinability depends on the physical properties of the metal in addition to the cutting conditions at hand. Aluminum has greater machinability then many other metals due to the fact that it is easy to shape and chip.

As a highly flexible and adaptable metal, aluminum is useful for various industrial applications that involve tooling and welding. It is also perfect for prototyping due to its low cost and formability benefits. Exceptional precision is desirable when machining aluminum.

Applications Using Aluminum Alloys
Due to its excellent machinability characteristic, aluminum is ideal for use in a number of different applications and products, including camera parts, cell phones, gears, door knobs, and machine parts.

Formability and Machinability Characteristics of Aluminum Alloyes
The classes of aluminum alloys listed below offer varying formability and machinability capabilities.

7xxx
This class of aluminum alloys consists of combinations of zinc and copper or zinc and magnesium. These alloys provide significant strength which also makes them less than ideal to form.

6xxx
Magnesium and silicon are added to this series of aluminum alloys. These alloys respond to formability well but are vulnerable to cracking. They’re generally used for extrusions meant for architectural applications.

5xxx
Magnesium is added to these alloys. They offer good formability.

4xxx
Commonly utilized for the manufacture of welding wire, these alloys include the addition of silicon

3xxx
This series of aluminum alloys contain approximately 1% manganese. They are highly applicable for forming applications and also do not manifest any perceptible loss of ductility.

2xxx
Also called copper alloys, this series of aluminum alloy has excellent machinability characteristics, but minimal cold formability, except when it is annealed.

1xxx
As approximately 99% pure aluminum, this series of alloys possesses high ductility.
