5182 aluminum bar is a premium-grade medium-strength, corrosion-resistant aluminum alloy bar made from AlMg4.5Mn0.4 (AA 5182 / EN AW-5182). This alloy is characterized by a high magnesium content that delivers excellent corrosion resistance, good weldability, and moderate mechanical strength while retaining the inherent lightweight advantage of aluminum. 5182 alloy is a non-heat-treatable wrought material, strengthened primarily through cold working, making it ideal for applications that require both durability and formability.
