SigmaChip A6 is a new
aluminium alloy based on AW 6026 that meets new
environmental standards but still retains very good
machinability and anodising qualities.
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 (see data sheet).
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
