Product Overview
Our Aluminum Strip (also known as aluminum slitting strip, aluminum band, or aluminum flat wire) is manufactured from high-quality aluminum coils through precision slitting, cutting, and rewinding processes. It offers excellent electrical and thermal conductivity, light weight, good corrosion resistance, and consistent dimensional accuracy. We supply aluminum strips in 1050, 1060, 1070, 3003, 5052 and 8011 alloys, in O, H14, H16, H18, H24 and H26 tempers, with custom widths, thicknesses, and coil sizes. Aluminum strips are widely used in transformers, heat exchanger fins, capacitors, cables, packaging, and general industrial applications.
