LD2 moderate intensity, in the hot state and annealed state plasticity high, easy in forging, stamping, in quenching and the natural state with LF21 as good corrosion resistance, easy to spot and atomic hydrogen welding, welding is acceptable. Machinability in quenching after aging can be. Used in the manufacture of plastic and high - corrosion resistance, medium load parts and complex shaped forgings.
LD2-2 LD2-1
Good corrosion resistance, good welding performance. It is widely used in the manufacture of large welding parts, forging and extrusion parts.
LD5
High strength aluminum forging, hot with high plasticity, easy in forging, stamping, heat treatment, process performance better, corrosion resistance is good, but there are the tendency of intercrystalline corrosion, cutting and welding, rolling and welding, contact good welding performance, welding, gas welding performance is not good. Used in the manufacture of complex and medium strength forgings and stamping parts.
