Item:233935534345Aluminium 4043 ARC Rods 2.5mm E95 ALUM 1KG Stick Welding Rods x 1KG PACKET MMA. MAC ALUM E95
Description & Applications:
Aluminium 4/5% silicon type electrode suitable for the welding of commercially pure aluminium and
similar alloys except those which contain magnesium or zinc as main alloying elements. Rapid
deposition rate, good penetration, excellent weldability and slag control. The special chemically
active mineral coating enables easy removal of surface oxides during welding, ensuring results of
high quality. Welding commercially pure aluminium where a slightly higher tensile is required and
for higher strength alloys of similar composition. Suitable for welding the wrought alloys H9, H20
and H30. The electrodes are unsuitable for welding alloys with high magnesium such as the 5% Mg
type.
