Alloy 4047 is an aluminium alloy that contains 12% Silicon, which is used for high silicon alloys and automotive work. Alloy 4047 is typically used where good colour matching to the parent material is important. Alloy 4047 is precision layer-wound for positive uninterrupted feeding. Alloy 4047 is suitable for gas-shielded MIG welding on both semi-automated and fully-automated system.
