Aluminium alloy 5005 contains nominally 0.8% magnesium. It has medium strength, good weldability, and good corrosion resistance in marine atmospheres. It also has the low density and excellent thermal conductivity common to all aluminium alloys. It is the most commonly used grade of aluminium in sheet and plate form. Aluminium alloy 5005 is a lean aluminium magnesium alloy which can be hardened by cold work: it is not heat treatable to higher strength.
This is a non-heat treatable alloy of aluminum with magnesium content. Cold working will strengthen (harden) the alloy and it is very good in both corrosion resistance and weldability. Commonly used in the manufacture of appliances, small boats, gas lines, refrigerator panels, and utensils. 5005 is also used in architectural components, and as an electrical conductor. Especially useful where excessive finishing costs are encountered in the use of 3003 alloys due to surface roughness upon drawing. This alloy is noted for excellent welding characteristics by all of the commercial methods. Filler metal of the same alloy should be used. Welding by resistance technique of the O (or annealed) temper material may require some trial and error determination of the best technique. Corrosion Resistance 5005 has the same high resistance to general corrosion as other non heat treatable aluminium alloys. It also has the higher resistance to slightly alkaline conditions common to the 5000 series alloys. The atmospheric corrosion resistance of 5005 is similar to that of 3003.
