MIG-hitsauslanka Esab OK Autrod 4047

OK Autrod 4047 on AlSi12-seosteinen alumiiniseosten MIG-hitsauslanka. Se soveltuu erilaisille AlSi-valuseoksille, mm. ns. silumiineille. Korkean piipitoisuuden ansiosta hitsisulan jähmettymisen lämpötila on matala ja lämpötila-alue hyvin kapea. Hitsisulan juoksevuus on suuri. Hitsiaine on hyvin vastuskykyinen kuumahalkeamia vastaan. Suojakaasu: Ar tai Ar+He (paksut aineet). OK Autrod 4047 was originally developed as a brazing alloy to take advantage of its low melting point and narrow freezing range. In addition, it has higher silicon content than OK Autrod 4043, which provides an increased fluidity and reduced shrinkage. The alloy produces bright and almost smut free welds. Hot cracking is significantly reduced when using OK Autrod 4047 as a filler alloy. The alloy may be used in applications of sustained elevated temperatures. Non-heat treatable.
