5356 Filler Rod Aluminum Wire Price

 The most widely used aluminum welding wires for welding are 4043 and er5356.

SAL4043, commonly known as ALSil, is an aluminum filler metal containing 5 percent silicon and can be recommended for welding 3003, 3004, 5052, 6061, 6063 and casting metals 355, 356 and 214. The melting point temperature range of ER4043 is 1065-1170oF, the color after anodizing is off-white, and the tensile strength is as low as 186MP.

Performance characteristics: It is a kind of aluminum-silicon alloy welding wire with great versatility. The weld metal has excellent thermal crack resistance and can also guarantee certain mechanical properties. However, in the case of anodizing treatment, the color of the weld metal and the base metal Differently, the welding of aluminum-magnesium-gold produces brittle Mg2Si in the weld, which reduces the plasticity and corrosion resistance of the joint.

Uses: Commonly used as filler material for argon arc welding and oxygen-acetylene gas welding of aluminum alloy workpieces and castings other than aluminum-magnesium alloys, especially for heat-treated aluminum alloys that are prone to thermal cracks, and can obtain better results.

SAL5356 is usually used as ALMg5, which is an aluminum alloy filler metal containing 5% magnesium. It can be used for MIG or TIG welding. It has good seawater corrosion resistance and can generally be applied to base metals 5050, 5052, 5083 , 5356, 5454 and 5456 welding. It is white in color after anodizing and has a tensile strength of 290MP.

Performance characteristics: This product is an alloy welding wire containing 5% magnesium. It is a general-purpose welding material with a wide range of uses. It is suitable for welding or surface surfacing welding of cast and forged aluminum alloys with 5% magnesium. It has high strength and can Good forgeability and good corrosion resistance. This product also provides good color matching for anodized welds.

Uses: bicycles, aluminum scooters and other sports equipment, locomotive carriages, chemical pressure vessels, ordnance production, shipbuilding, aviation and other industries.

Attention should be paid to the selection of aluminum welding wire:

1) Crack sensitivity of welded joints

The direct factor affecting crack sensitivity is the matching of base metal and welding wire. The weld metal with a melting temperature lower than that of the base metal can be selected to reduce the crack sensitivity of the weld metal and the heat-affected zone. For example, when welding 6061 alloy with a silicon content of 0.6%, the same alloy is used as the weld, and the crack sensitivity is very high.

However, ER4043 welding wire with 5% silicon content has good crack resistance because its melting temperature is lower than that of 6061 alloy and it has higher plasticity during cooling. In addition, the weld metal avoids the combination of magnesium and copper because of the high crack susceptibility of Al-Mg-Cu.

2) Mechanical properties of welded joints

The strength of industrial pure aluminum is the lowest, the 4000 series aluminum alloy is in the middle, and the 5000 series aluminum alloy has the highest strength. Although aluminum-silicon welding wire has high crack resistance, the plasticity of silicon-containing welding wire is poor. Therefore, silicon-containing welding wire should be avoided for joints that require plastic deformation after welding.

3) Performance of welded joints

In addition to the composition of the base metal, the choice of filler metal is also related to the geometry of the joint, the corrosion resistance requirements during operation, and the appearance requirements of the weldment. For example, welded containers for storing hydrogen peroxide require high-purity aluminum alloys in order to provide good corrosion resistance to the container or to prevent contamination of it by the stored product. In this case, the filler metal must be at least as pure as the parent metal.

Generally speaking, ER4043 and er5356 mig wire are the most widely used aluminum alloy welding wires in aluminum alloy welding. We can choose more suitable welding wire according to the application requirements after welding.
