Aluminum Alloys France | A-G 4,5 MC

A-G 4,5 MC is a high-magnesium aluminum alloy containing approximately 4.5% magnesium, designed for applications requiring excellent corrosion resistance, especially in marine and chemically aggressive environments. It offers high strength among non-heat-treatable aluminum alloys, combined with good weldability and fatigue resistance, making it ideal for forged components in shipbuilding, offshore structures, and pressure vessels. Despite its strength, the alloy maintains good formability, allowing for the production of complex and durable parts. At Rosswag, we manufacture precision-forged components from A-G 4,5 MC using advanced open-die forging and machining. This alloy is a strong and reliable choice for demanding structural applications in harsh operating conditions.
