Aluminium

Magnesium alloyed aluminum wire for TIG welding of salt water resistant Al-Mg alloys containing up to 5% Mg. The welding wire is the most used type and intended for welding alloys corresponding to, for example, ENAW-5083 (SS 4140) where high strength of the weld joint is desired. Base material in the 5XXX series which together with OK Tigrod 5356 gives a weld metal with more than 3% Mg has good resistance to cracks caused by stress corrosion even where the operating temperature exceeds 65ºC. The alloy 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.

Silicon alloy aluminum electrode with a special flux-type casing. The electrode is intended for welding cast so-called silumin alloys containing approx. 12% Si, for example engine blocks, gearboxes, fittings etc. as well as to rolled alloys with corresponding strength such as SS-EN 4104, 4212, 4260 and 4261. The melting of the electrode takes place about three times as fast as when welding with ordinary coated electrodes intended for welding steel. The electrode diameter is chosen according to the thickness of the goods. OK 96.50 must be held perpendicular to the workpiece with the shortest possible arc. Preheat the workpiece or at least the starting point to 200-300°C. OK 96.50 has a very easy-flowing slag. The slag should be completely washed off with water. OK 96.50 can also be used for gas welding/soldering, whereby the casing acts as a flux. The electrodes must be stored dry and the packaging should not be left open for longer than necessary.

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.

Silicon alloyed aluminum wire of type AlSi5 for TIG welding of AlMgSi and AlSi alloys with silicon contents up to 7%. The wire is recommended for e.g. EN-AW-6063 (SS4104), EN-AW-6082 (SS4212), EN-AW-42000 (SS4244), EN-AW-42100 (SS4245) and corresponding Al alloys according to other standards. The welding material has a high safety against cracks. Color matching between weld metal and base material during anodizing is less good. As with all aluminum welding, a high degree of discipline applies regarding cleanliness and minimization of oxide layers on joint surfaces and additive materials.

Developed to provide a weldment with the highest possible tensile strength in the welded state of EN-AW-5183 and corresponding alloys with high magnesium contents. The more general alloy type OK Tigrod 5356 has lower strength and does not reach EN-AW-5183 in the as-welded condition. The alloy is used in marine and building constructions where high strength and good corrosion resistance are desired. The alloy type is not recommended at elevated temperatures due to the risk of stress corrosion cracking. The alloy cannot be heat treated.

Originally developed as a solder alloy for its low melting point and narrow melting range. Therefore, it has a higher Si content than OK Tigrod 4043, which gives increased surfaceability and reduced risk of shrinkage. The risk of hot cracking is significantly reduced when OK Autrod 4047 is used as an additive material. The alloy can be used in applications with sustained high operating temperatures. The alloy cannot be heat treated.
