AlMg material is an alloy composed of aluminum and magnesium, typically with magnesium content ranging from 1.5% to 6%. The addition of magnesium enhances the strength and hardness of the alloy, while also improving its corrosion resistance. Other elements, such as copper and silicon, may also be added to further enhance the material’s properties. The exact composition of AlMg material can vary depending on its intended use and specific application.
