A general purpose aluminium rod containing 5% magnesium that has excellent corrosion resistance and high strength. Suitable for welding magnesium bearing aluminium alloys such as: • 5251 (N4) • 5154 (N5) • 5454 (N51) • Also heat treatable alloys: • 6063 (H9) • 6061 (H20) • 6082 (H30).

An Aluminium alloy with 5% silicon giving excellent flow characteristics and penetration. Suitable for welding: • Duralumin • Cast (LM25) and wrought alloys 6063 (H9) • 6061 (H20) • 6082 (H30) • Weld will discolour if anodised.

Aluminium alloy containing 5.3% Magnesium: all elements are closely controlled for optimum weld strength. • Normally used on 5083 (N8) and for military applications.

A pure aluminium (99.5% min) shaved rod which produces a ductile weld equal in strength to that of the base metal. • The weld is capable of being hammered, stretched and drawn into shape without fracture.

Aluminium rod containing 12% silicon. • It has good mechanical properties, excellent corrosion resistance • Suitable for silicon bearing cast aluminium alloys and wrought alloys • Do not use if fabrication is to be anodised.

Special aluminium alloy containing: • 5% Magnesium • 0.75% Manganese • For improved weld strength.

Magnesium rod with 6% Aluminium suitable for welding magnesium aluminium alloy castings of similar composition, crankcases, gearboxes, sumps, wheels etc.
