SIF SIFAlumin No.27 Aluminium TIG Filler Rods - 5% Magnesium - 1.6 to 3.2mm Dia. - 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.
