Pure aluminum is soft and malleable, and most commercial applications require greater strength than pure aluminum provides. Additional strength is achieved by adding other metal elements to produce alloys. And, some alloys can be heat-treated or cold-worked by different methods to increase their strength and hardness even further. Hydro produces extrusion in 6000 and 7000 series alloys, but some applications may require aluminum in other alloys we do not typically extrude such as 1000, 3000, and 5000 series.
Aluminum 5052 alloy is one of the higher strength, non-heat-treatable alloys, which contains magnesium as its major alloying element, with small amounts of chromium, silicon, iron, copper, manganese and zinc. When annealed, alloy 5052 is stronger than the readily available 1100 and 3003 alloys, and stronger than most other 5xxx series alloys. 5052 alloy cannot be heat treated, but can be hot and cold worked.
The properties of 5052 aluminum include good workability, making it very useful in forming operations. It has very good corrosion resistance, especially to salt water, and can be easily welded. Its high fatigue strength makes it an excellent selection for structures that need to withstand excessive vibrations. Alloy 5052 is commonly used in sheet, plate and tube form. However, this alloy is rated only fair for machinability, so it is not the best choice for extensive machining operations without oil lubricants.
Aluminum alloy 5052’s excellent resistance to corrosion makes it particularly well-suited to shipbuilding and marine applications, such as marine components, fuel tanks and oil lines. Due to its light weight, high strength and attractive finishing capabilities, it can be used to make smaller, thinner components, such as those used in consumer electronics.
In fact, alloy 5052 is the preferred choice for consumer electronics casings, as well as for larger products, such as laptop computers, mobile devices and televisions. Other common applications for aluminum alloy 5052 include fuel and oil lines, hydraulic tubes, heat exchangers, pressure vessels, appliances like home freezers, kitchen cabinets, fencing, lighting, wiring and rivets. It is regularly used in general sheet metal work.
