Aluminum 4043 Sheet

Almigweld and altigweld 4043 can be classed as a general purpose type filler alloy.

Aluminum 4043 sheet. 5xxx series magnesium is the primary alloying agent in the 5xxx series and is one of the most effective and widely used alloying elements for aluminum. 4043 offers good fluidity and less crack sensitivity than 5356 when welding 6000 series base metals. Aluminum sheet metal comes in a variety of thicknesses and weights in many different grades. You can also choose from plate aluminum sheet 4043 as well as from 5000 series 3000 series and 1000 series aluminum sheet 4043 and whether aluminum sheet 4043 is punching bending or cutting.

Al4043 can be classed as a general purpose type filler alloy. Due to the addition to silicon alloy 4043 results in improved fluidity wetting action to make alloy 4043 the preferred choice by welders. The silicon addition improves puddle fluidity producing an appealing bead profile. As a basic description we can say that 4043 is an aluminum filler alloy with 5 silicon added and that 5356 is an aluminum filler alloy with 5 magnesium added.

It is most often used to weld the 6xxx series of alloys. 4043 is an aluminum silicon filler metal designed for welding heat treatable base metals and is a common choice for welding 6061. There are some misconceptions within the industry that you can successfully weld any aluminum base alloy with either 4043 or 5356 filler alloy. Alloy 4043 is one of the most widely used filler alloys for welding 6xxx series alloys for structural and automotive applications.

About 6 of these are aluminum sheets. The silicon additions result in improved fluidity wetting action to make the alloy a preferred choice by welders. A wide variety of 4043 aluminium sheet options are available to you such as processing service surface treatment and grade. Ryerson offers heat treatable aluminum sheet grades like the popular 6061 aluminum alloy that can be used for commercial applications that require strength corrosion resistance and machinability as well as non heat treatable grades when formability and weldability are priorities.
