Aluminum 5083, the strongest of the non-heat-treatable alloys, is made from the finest grade raw material available while remaining a cost-effective choice. It maintains good formability in the tempered condition, and takes welding and cold working well. Due to its excellent thermal conductivity, resistance to corrosion, and ability to withstand low temperatures, this alloy is best suited for marine and cryogenic applications. It is not recommended for use in temperatures above 65ºC. Continental Steel offers this alloy in the form of channels, along with other various shapes.
