Description

SIFAlumin No27 TIG Rods x 1.6mm x 2.5Kg

SIFAlumin No27 TIG Rods are general-purpose aluminium rods containing 5% magnesium, offering excellent corrosion resistance and high strength. They are designed for welding magnesium-bearing aluminium alloys such as 5251 (N4), 5154 (N5), 5454 (N51), and heat-treatable alloys like 6063 (H9), 6061 (H20), and 6082 (H30). These rods are versatile and can be used in both TIG and oxy/acetylene welding. When used in oxy/acetylene, it’s recommended to pair with Sif No.36 aluminium brazing and welding flux.

Features and Benefits:

  • High Magnesium Content: Contains 5% magnesium for enhanced corrosion resistance and strength.
  • Versatile Welding: Suitable for TIG and oxy/acetylene welding.
  • Compatibility: Ideal for welding magnesium-bearing aluminium alloys and heat-treatable alloys.
  • Preparation Flexibility: Can be used with Sif No.36 aluminium brazing and welding flux for oxy/acetylene welding.

Common Applications:

  • Diverse Alloys: Suitable for welding forged and cast aluminium-manganese/aluminium-magnesium components and dissimilar aluminium alloy grades with a max of 5% Mg.
  • Anodising: Can be used for components set to be anodised later.
  • General Use: Perfect for plate, pipe, tube, and component welding.

Welding Positions:

Suitable for all positions, except vertical down.

Material to be Welded:

Suitable for welding forged and cast aluminium-manganese/aluminium-magnesium components and dissimilar aluminium alloy grades containing a maximum of 5% Mg. Can also be used to weld components which are to be subsequently anodised. Pre-heating up to 120°C may be necessary, subject to material size and thickness. Wire brushing between passes is recommended to ensure removal of surface oxide build-up. Suitable for use on plate, pipe, tube, and components. Ensure that parent metal surface is cleaned and fully degreased prior to welding.
