2011 T3 Bar
Extruded and drawn machining bar with high mechanical strength that machines exceptionally well.
Aluminium alloy 2011 is a high mechanical strength alloy that machines exceptionally well. Often called a Free Machining Alloy or ‘FMA’ it is well suited to use in automatic lathes.
Machining at high speeds produces fine chips that are easily removed. The excellent machining characteristics allow the production of complex and detailed parts. In some circumstances 2011 can replace free machining brass without the need for alterations to tooling.
It has poor corrosion resistance, which means parts made from 2011 tend to be anodised to provide additional surface protection.
When higher levels of corrosion resistance are required, 6262 T9 may be a suitable replacement.

Merkmale
- Machining at high speeds produces fine chips that are easily removed. The excellent machining characteristics allow the production of complex and detailed parts. In some circumstances 2011 can replace free machining brass without the need for alterations to tooling.
- It has poor corrosion resistance, which means parts made from 2011 tend to be anodised to provide additional surface protection.
- Alloy 2011 has extremely poor weldability and thus welding is not recommended. However, as it is used for machined parts there is rarely a need to weld this alloy.
