Aluminium

Silicon alloy wire electrode for gas metal arc welding of Al-Si alloys with silicon contents up to 7% corresponding to EN-AW-6063, EN-AW-6082, EN-AW-42000, EN-AW-42100. OK Autrod 4043 is one of the most widely used alloy types for welding and brazing and can be said to be a universal solution as an additive. The silicon content provides good surfaceability of the melt with good wetting properties and is a good choice for the welder. The alloy is not sensitive to cracks and produces a bright, almost soot-free weld. The alloy type is not recommended for anodizing and cannot be heat treated.

The most widely used alloy type for welding aluminum alloys. OK Autrod 5356 is a magnesium alloy aluminum wire for MIG welding of salt water resistant Al-Mg alloys containing up to 5%Mg, but was also used for its relatively high strength. Alloys of type 5XXX, which are welded with OK Autrod 5356 and give a weld metal with more than 3% Mg, can be sensitive to cracks caused by stress corrosion at a working temperature above 65°C. The alloy cannot be heat treated.
