Electrically Conductive Aluminum Tape

Electrically conductive aluminum tape 1060 has high plasticity, corrosion resistance, electrical conductivity and thermal conductivity. 1060 aluminum tape is formed by adding a small amount of copper to pure aluminum. The electrical and thermal conductivity of aluminum is only lower than that of conventional metals with copper. The electrical conductivity of the metal is in order: silver --Copper-gold -aluminum-nickel-steel alloy. Since the price of copper is much higher than that of aluminum, the current commonly used material for transformer winding foil strip is aluminum strip. Transformer aluminum strip grades are mainly A1060 (O), which are mainly used in the high and low voltage windings of dry-type transformers as electrically conductive materials.

Aluminum alloy has low density, but relatively high strength, close to or exceeds that of high-quality steel, good plasticity, high conductivity, soft quality, smooth surface, no burrs, it is an ideal material for the production of dry-type transformers. And electrically conductive aluminum tape is the key to manufacturing transformer windings raw material. It has very high requirements on the electrical conductivity, burr curling, side bending, surface quality and other technical indicators of aluminum strip and foil for transformer winding.

The conductive properties of aluminum have been incorporated into conductive materials. Aluminum and copper alloys are two commonly used conductive materials. Aluminum is much more stable in nature than copper, and copper is easily corroded and rusted by water (patina) , And aluminum will quickly produce a dense oxide film in the air to prevent further oxidation of aluminum, and the specific gravity of aluminum is only one-third of copper, which greatly saves the difficulty and cost of later processing. Thus, electrically conductive aluminum tape is considered to be a good substitute for copper tape.
