ESAB OK AlSi5
The ESAB OK AlSi5 is an aluminum-silicon stick electrode designed for welding aluminum alloys, particularly AlMgSi-alloys like EN AW 6060/6063, 6005, and 6201. This electrode also works well for welding AlSi5Cu and AlSi7Mg castings. Its 5% silicon content reduces hot cracking, ensuring smooth welds on aluminum components. Packaged in an airtight tin can, it maintains quality and moisture resistance, ready for use in demanding environments. The AlSi5 alloy is equivalent to ER 4043, a widely used filler metal for aluminum welding.
OK AlSi5 is suited for DC+ welding and features a chloride and fluoride salt coating, which in fact stabilizes the arc for excellent weld quality. This electrode is especially useful for automotive, marine, and general aluminum repairs.
