The common alloy of 1000 series aluminum pipe: 1050, 1060, 1070.
1 series aluminum is industrial pure aluminum. It has high plasticity, corrosion resistance, electrical conductivity, thermal conductivity and other characteristics. But the strength is low, the heat treatment cannot be strengthened, and the machinability is poor. It can be used for gas welding, hydrogen atom welding and contact welding, but is difficult to braze. 1 series aluminum is easy to bear various pressure processing, extension and bending.
