Aluminiuim 2011

 

aluminiumhp

 

Alloy 2011 is a high mechanical strength material that machines exceptionally well. It is well suited to use in automatic lathes, as it is a free machining alloy.
The excellent machining characteristics of 2011 allow it to be cut into complex and detailed shapes successfully.

 

 

Alloy 2011 is typically used for the following applications…

·Appliance parts & trims
·Automotive trims
·Fasteners & fittings
·Ordnance

 

Aluminium 2011 is available from us in bar in the following sizes…
In the drawn condition:
3mm dia - 3” dia

In the extruded condition:20mm dia- 180mm dia
