注記: Longitudinal mechanical properties of pipe at room temperature

●Main features and application range of 1070 アルミニウム:

1070 industrial pure aluminum has the characteristics of high plasticity, 耐食性, good electrical conductivity and thermal conductivity, but low strength,
Without strengthening by heat treatment, the machinability is not good, and contact welding and gas welding are acceptable. Make more use of its advantages to create a
Some structural parts with specific properties, such as gaskets and capacitors made of aluminum foil, electronic tube isolation nets, wires,
Protective sleeves, nets, wire cores for cables, parts and decorations for aircraft ventilation systems.

●1070 aluminum heat treatment process:

Carry out oil quenching and tempering. The strength of this type of steel wire is not as good as that of lead-bath treated steel wire, but its performance is uniform,
The cost is lower. After cold roll forming, stress relief treatment is carried out. Pulled to the specified size, and then annealed.
After the softened cold roll is formed, it needs to be quenched and tempered at medium temperature to obtain the required mechanical properties.
