Electrical resistivity – 5052 alloy has about 7% less electrical conductivity than 6061 aluminum.
Corrosion Resistance Properties Of 5052 vs. 6061 Aluminum
Exposure of aluminum alloys to air results in the formation of an oxide layer. The layer makes the aluminum alloy to be non-reactive to corrosive substances. Remember, the absence of copper in 5052 alloys makes them cope well in moist environments.
It is more preferred in marine and chemical applications than 6061 alloys. When both 6061 and 5052 alloys are exposed to alkaline soil a pitting reaction occurs. 5052 and 6061 alloys have magnesium which resists corrosion. An aluminum coating is used on alloys to act as a protective layer and avoid corrosion.
Weldability Properties Of 5052 And 6061 Aluminum
Both 5052 and 6061 alloy aluminum are characterized by excellent properties of weldability. Of all aluminum alloys, 5052 alloys have the best welding properties. Its formidability feature makes it perfect for the fabrication of electrical enclosures. 6061 alloys require proper selection for filler metal during welding aluminum. For good finish products, you must apply post-weld aging and heat treatment.
