5051 aluminum sheet is a medium-strength aluminum-magnesium alloy sheet, available in various thicknesses. Send a message for more pricing details.
5051 aluminum is a non-heat-treatable alloy from the 5000 series, with magnesium as its main alloying element. The magnesium content, at about 2%, gives this material a strong balance of strength, formability, and long-term durability. Because of this composition, 5051 aluminum sheet performs well in demanding environments.
One of the key characteristics of 5051 aluminum alloy is its excellent corrosion resistance, especially in humid and marine conditions. It also offers moderate mechanical strength and very good weldability, making it easy to process, bend, and fabricate without cracking. These features help reduce production costs while maintaining reliable performance.
Thanks to its stable properties, 5051 aluminum sheets are widely used in automotive and motorcycle components, industrial hardware, marine parts, and pressure vessels. These applications often require materials that combine strength, corrosion resistance, and good workability, all of which 5051 aluminum provides.
As a professional aluminum sheet supplier, Zggdmetal supplies 5051 aluminum sheet in multiple tempers, including O, H112, H32, and H34, to meet different forming and strength requirements. In international standards, the North American designation is AA 5051, while the European standard is EN AW-5051.
