Sino Welding supplies a complete range of aluminium MIG and TIG welding wires for industrial and commercial applications. Our aluminium welding consumables are manufactured to meet AWS and ISO international standards, widely used in aerospace, automotive, shipbuilding, and structural fabrication.
We offer the most common aluminium filler alloys including ER4043 and ER5356, available in standard spool weights and straight cut lengths. Wire diameters range from 0.8mm to 3.2mm to suit both MIG and TIG welding processes.
As an experienced aluminium welding wire supplier based in China, we provide competitive factory pricing, flexible MOQ, and reliable export packaging for customers worldwide. Custom specifications and OEM labeling are available upon request.
Continuous spool wire for MIG (GMAW) welding of aluminium alloys. Available in 0.8mm, 1.0mm, 1.2mm diameters on D100, D200, and D300 spools.
Straight cut lengths for TIG (GTAW) welding. Standard length 1000mm, diameter from 1.6mm to 3.2mm. Supplied in tubes or plastic bags.
ER4043 is a silicon-bearing aluminium filler alloy recommended for welding heat-treatable base alloys. It offers excellent fluidity, reduced cracking sensitivity, and a bright weld appearance. Suitable for MIG and TIG welding of 6000 series aluminium alloys.
AWS Classification: ER4043
Silicon content: 4.5–6.0%
Available diameters: 0.8 / 1.0 / 1.2 / 1.6 / 2.0 / 2.4 / 3.2 mm
Spool: 0.5kg / 2kg / 7kg / 10kg
ER5356 is a magnesium-bearing aluminium filler wire with higher strength than ER4043. It is the most widely used aluminium welding wire, suitable for welding 5000 and 6000 series base metals requiring higher tensile strength.
AWS Classification: ER5356
Magnesium content: 4.5–5.5%
Available diameters: 0.8 / 1.0 / 1.2 / 1.6 / 2.0 / 2.4 / 3.2 mm
Spool: 0.5kg / 2kg / 7kg / 10kg
Our aluminium MIG TIG welding wires are widely applied in:
Automotive body and component manufacturing
Aerospace structural welding
Marine and shipbuilding fabrication
Bicycle and sports equipment frames
Heat exchangers and pressure vessels
General aluminium sheet metal fabrication
With over 20 years of experience in welding consumables export, Sino Welding provides stable quality, competitive pricing, and professional technical support. All aluminium welding wires are produced under strict quality control and are available with Mill Test Certificates (MTC). We ship to Europe, North America, Southeast Asia, and the Middle East regularly.
