1070 HO/O Aluminum Strip for Transformers

The Introduction of 1070 HO/O Aluminum Strip for Transformers

1070 aluminum strip is a pure aluminum alloy with an aluminum content of more than 99.7%, which is widely used in transformers. 1070 aluminum strip has high plasticity, corrosion resistance, electrical conductivity and good thermal conductivity, but low strength, not strengthened by heat treatment, poor machinability, and acceptable for contact Welding, gas welding. 1070 – O/HO aluminum foil strip for transformer winding, also known as 1070 aluminum transformer strip foil, mainly used for dry type and oil-immersed transformer winding. The thickness ranges of 1070 aluminum foil strip for transformer from 0.2mm to 3.00mm and width ranges from 10mm to 1500mm.
