2011 Aluminium Alloy

Commercial Aluminium

2011 Commercial Aluminium Alloy

Alloy 2011 is known as a free-machining alloy or 'FMA' - this means that the material has excellent machinability and is suitable for use on automatic lathes.


The alloy displays poor corrosion resistance and therefore, anodising will be required for additional surface protection. Whilst weldability is also very poor, 2011 aluminium is a highly versatile material. With excellent machinability, the product finds use in the manufacture of highly complex and detailed parts.

Machining Capabilities

As a free-machining alloy, 2011 aluminium offers excellent versatility and in specific scenarios will replace free-machining brasses without the need for changes in tooling. The alloy is highly suitable for any manufacturing process requiring repetitive machining.

Typical Applications

Commercial applications for this engineering material include:

We stock 2011 in flats, round bar, round tube, square bar and hexagon bar.

Technical Assistance

Our knowledgeable staff and resident metallurgists will be pleased to assist you further on any technical topic. Smiths Metal Centres Limited also boasts an in-house UKAS Accredited Testing Laboratory which is unique within the multi-metal and plastic stockholding sector. We believe this underlines our total commitment to quality and our ethos of being the complete service provider.
