Alloy 4043 is one of the oldest and most widely used welding and brazing alloys. Almigweld and Altigweld 4043 can be classed as a general purpose type filler alloy. The silicon additions result in improved fluidity (Wetting Action) to make the alloy a preferred choice by welders. The alloy is less sensitive to weld cracking and produces brighter, almost smut free welds.

AlcoTec produces "ALTIGWELD" filler rods in 36 inch (914mm) straight lengths designed for gas tungsten-arc (GTA) welding or brazing operations. The AlcoTec cleaning system and quality control process routinely ensures surface cleanliness and metallurgical integrity of the rods. Each rod is also embossed with the alloy identification every six inches.
