Description

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 areeasily removed. The excellent machining characteristics allow the production of complex and detailed parts. In some circumstances 2011 canreplace free machining brass without the need foralterations to tooling.It has poor corrosion resistance, which means partsmade from 2011 tend to be anodised to provideadditional surface protection.When higher levels of corrosion resistance arerequired, 6262 T9 may be a suitable replacement.
