5 series aluminum alloy are Al-Mg alloy. Its main types are 5052,5182,5083,5086 and 5251 aluminum sheet. What are their properties and uses? Welcome to read this page.

5 series aluminum alloys are the Aluminum-Magnesium alloys. They exhibit a very good combination of high strength, resistance to corrosion, formability, and good weldability. The main types are 5052, 5182, 5083,5086 and 5251aluminum sheet.

5052 Aluminum Sheet

The 5052 aluminum sheet is of higher strength and greater corrosion resistance (including to salt water). At the same time, it also has better finishing characteristics. Because of such excellent properties, it is generally used for interior parts of the boat such as cabins, decks, and gunwales. In addition, it is also used to food processing equipment,high-end mobile phone casings, high-end air-conditioning casings.

5182 Aluminum Sheet

5182 aluminum sheet and 5052 aluminum sheet are both aluminum-magnesium alloys. It has good corrosion resistance, good weldability, cold workability, and medium strength. Besides, its surfaces are very bright after polishing.

However, the 5182 aluminum has a higher magnesium content than the 5052 aluminum and a small amount of silicon is added, so the weldability is better than the 5052 aluminum. Therefore, the 5052 aluminum is mostly used for can lids, and the 5182 aluminum strip is mostly used for pull rings.1570679039.jpg

5083 Aluminum Sheet

5083 aluminum sheet is stronger than 5052, yet it’s still formable and easily welded. This aluminum alloy is widely used in chemical and marine environments where corrosion resistance is crucial and can also withstand extremely cold temperatures without becoming brittle.Correspondingly,its price is higher than 5052 aluminum.

5086 Aluminum Sheet

5086 aluminium sheet is very similar to 5083 aluminum, but its corrosion resistance to salt water is stronger. It is the most popular choice for hull bottoms and side sheets.

5251 Aluminum Sheet

5251 aluminum sheet is of medium strength, good ductility and easily weldable. It also possesses high corrosion resistance particularly in marine environments, therefore 5251 aluminum is widely used in boats, aircraft parts, vehicle panels.
