MasterWeld MW-4047 AlSi12 Aluminium Welding Wire is particularly used to prevent solidification cracks in connection with high dilution and clamp conditions. This filler wire should not be used if you are considering the best colour match after post weld anodizing, as it will typically turn dark grey in colour after the anodizing process because of the silicone content.
