• Thin plates (0.5mm–3mm)

  Use thinner wires (0.8mm–1.2mm) to better control heat input and reduce the risk of burn-through. MIG welding is recommended for more precise joints.

• Medium thickness (3mm–6mm)

  Wire diameters between 1.2mm and 1.6mm are suitable for ensuring enough deposited metal during welding. Both MIG and TIG welding are suitable, with MIG being more efficient for faster work.

• Thick plates (6mm–12mm)

  Larger diameter wires (1.6mm–2.4mm) help ensure proper joint strength and weld integrity. TIG welding is commonly used to achieve clean and consistent results.

• Extra thick plates (over 12mm)

  Wires from 2.4mm to 6.0mm support higher deposition rates for heavy-duty applications. TIG welding or multi-pass welding techniques are recommended to ensure full penetration.

For best results, select welding wire based on the thickness of the material, welding method, and required mechanical performance. This ensures better control, productivity, and weld quality.

• Pure aluminium plates

  ER1070 is recommended for materials like 1060 aluminium. It offers excellent electrical and thermal conductivity, which is ideal for welding pure aluminium.

• 5000 series aluminium alloys

  ER4043 is suitable for 5xxx series such as 5052 and 5083, known for its good weldability and flow characteristics.
  ER5183 is a better match for high-strength grades like 6061-T6, providing stronger welds.

• 6000 series aluminium alloys

  ER4043 is a versatile option for 6xxx series, including 6061 and 6082.
  ER5087 is used for materials like 6005A, 6082, and 5083, offering excellent resistance to cracking and porosity, along with strong mechanical properties.

• Aluminium-magnesium alloys

  ER5356 is often used for alloys such as 5052 and 5083, thanks to its corrosion resistance and solid mechanical performance.

When selecting welding wires, consider the alloy grade, material thickness, hardness, and the specific working environment. For harder alloys, ER5183 is a solid choice. For corrosion resistance and mechanical strength, ER5356 or ER5556 may be more suitable. Always match the welding wire to your actual welding needs to ensure strong, stable, and high-quality results.

Choosing the right aluminium welding wire involves multiple factors, such as the base metal composition, plate thickness, service environment, mechanical requirements, and any special conditions. Below are some detailed recommendations:

• Pure aluminium:

  ER1070 and ER1100 wires are commonly used for welding pure aluminium and alloys that require good corrosion resistance and electrical conductivity.

• Aluminium-silicon alloys:

  ER4043 and ER4047 wires are ideal for welding aluminium-silicon alloys and grades with lower weldability. ER4043 is widely used for general welding; ER4047 offers better flow and higher silicon content.

• Aluminium-magnesium alloys:

  ER5356 is suitable for welding aluminium-magnesium alloys and applications requiring higher strength and durability.

• Aluminium-copper alloys:

  ER2319 is recommended for aluminium-copper alloys and high-strength aluminium grades.

• For base metal thickness under 8 mm, a 1.2 mm diameter wire is typically used.
• For 8 mm and above, a 1.6 mm wire is preferred for better control and weld quality.

• For demanding environments, such as chemical processing applications, wires with good corrosion resistance like ER5356 are recommended.
• For heat-treatable aluminium alloys that are prone to hot cracking, silicon-based wires such as ER4043 can help minimize cracking during welding.

• When welding alloys like 6005A, 6082, or 5083, where high strength and crack resistance are required, ER5087 (AlMg4.5MnZr) is a good option.
• This wire also performs well in preventing porosity and maintaining strong mechanical properties.

• Some special aluminium alloys may require customized wires with added elements like titanium, vanadium, or zirconium to improve weldability.
• For parts that will be anodized, avoid silicon-containing wires to prevent black discoloration in the weld zone.
• In laser welding applications, the welding wire must match the laser system requirements, including diameter, deposition rate, and penetration depth.

• Straight wire diameter: 1.6/2.0/2.4/3.0/3.2/4.0/5.0/6.0mm (carton box, 1000mm length)
