2618 Aluminium Block Bar

Introduction and specifications of 2618 Aluminium Block Bar
As high-strength forged aluminum, 2618 Aluminium Block Bar has high plasticity in hot state and is easy to forge. Stamping; it can be strengthened by heat treatment, and its strength after quenching and artificial aging is similar to that of duralumin; it has better process performance, but has an extrusion effect. , So the longitudinal and lateral properties are different; the corrosion resistance is good, but there is a tendency for intergranular corrosion; the machinability is good, resistance welding, spot welding, seam welding performance is good, arc welding and gas welding performance is not good.
