NT·ER4047

AWS A5.10 ER4047 ISO 18273-S Al 4047

DESCRIPTION

NT·ER4047is a eutectic aluminum-silicon welding wire containing 12% silicon; It has excellent welding performance with smooth arc, low spatter level, beautiful and bright bead appearance. Characteristics of welding wire:
1. Compared with 4043, it has lower melting point and narrower solidification range, better fluidity of molten pool, reduced hot cracking tendency and increased shear strength of fillet weld;
2. The product is applicable for continuous welding work in high temperature environment (such as above 65℃).

APPLICATIONS

The product is applicable for welding all kinds of cast and extruded aluminum alloys, such as aluminum (thin) parts, condensers, air conditioning pipes, automobile water tanks, oil tanks and so on.

PROCESS

100% CO2 or Ar mixed gas
