how to choose aluminium material for the aluminium machining

Jul. 17, 2021

Choose the right alloy: Not all aluminum alloys are equal in price. If the part is only a prototype, it may not be necessary to use the most advanced and expensive alloy. To learn more, contact us directly   

Aluminum 5052

This aluminum alloy uses magnesium as its primary alloying element. It is very corrosion-resistant due to the lack of copper in its composition but it cannot be heat-treated. Aluminum 5052 is typically used in fuel tanks, sheet metal parts, and fuel/oil lines.

Aluminum 6061

This grade of aluminum is considered a general-purpose alloy. It has excellent machinability characteristics and can be easily welded. The primary alloying elements are magnesium and silicon. This aluminum alloy is regularly used to make electrical fittings, brake pistons, and bike frames.

Aluminum 7075

This alloy is slightly stronger than 7050 aluminum and has very good fatigue resistance, making it ideal for applications that undergo cyclic loading. Its main alloying element is zinc and its typical applications include meter shafts and gears, aircraft fittings, and shaft keys.

Aluminum ADC-12

This aluminum alloy is cast specifically for applications that require highly accurate components like assembly jigs, test structures, and fixture plates. It is well-suited to these applications because its crystal structure has no internal stresses. It also allows for high-speed machining without the significant distortion common in other aluminum alloys.

Finishes and Post-Processing Options

Xu Feng offers a wide range of surface finishes suitable for aluminum alloys. The most popular surface finishing process is anodization. Both normal- and hard-coating anodizing are offered to improve the wear resistance and the corrosion resistance of the various available alloys. Chemical conversion coating and metal plating are also available for aluminum alloys.
