Our SigmaChip A6 alloy has been updated to allow it to be used in applications that are impacted by new European environmental legislation regarding maximum allowable lead (Pb) content in finished components.
This legislation particularly effects automotive and electrical applications and the chemical composition of SigmaChip A6 has been changed accordingly. This has also resulted in a change in the mechanical properties of SigmaChip A6. SigmaChip A6 finds many applications as a replacement for AW 6262 (which has an allowable lead (Pb) content that makes it incompatible with specific elements of the new European environmental legislation). It is also suitable for many applications as an alternative to AW 6061, AW 6082 and AW 6012.
SigmaChip A6 is especially suited to turned parts manufacture where speed and aesthetic component finish have equal importance.
The standard AW 6026 aluminium alloy has been optimised for consistent machinability. SigmaChip A6 is especially recommended for such components that have anodising or superior corrosion resistance is an additional requirement. Short, tightly curled chips and rapid metal removal rates ensure greatly reduced machining times over all-purpose grades such as 6082/H30, together with an excellent, bright surface finish.
These attributes are combined with very good anodising and corrosion resistance.
