1060 aluminum strip for transformer is the key raw material for the manufacture of transformer windings, and it is the aluminum ribbon obtained by embossing aluminum ingots. The dry-type transformer aluminum strip and foil national standard is suitable for the uniform standard of dry-type transformer aluminum strip and foil material. The transformer aluminum strip is divided into different grades, specifications and states according to the application. The grades include 1060, 1050, 1050A, 1060, 1070, 1070A and 1350. The state is O. O represents a soft state, and the degree of hardness and annealing can be indicated by numbers. The thickness is between 0.08 and 3.00. Formal name of the strip foil is aluminum tape and foil for dry transformers.

The 1060 aluminum strip foil for transformer is made of high-quality pure aluminum. It has a high electrical conductivity and a soft texture. The surface is smooth and burr-free. It is an ideal material for the production of dry-type transformers and a key raw material for manufacturing transformer windings. Many technical indexes such as electrical conductivity of aluminum strip and foil, burr curling, side bending and surface quality are required.

Aluminum strips and foils for dry-type transformers are generally made of 1060 aluminum foil strips, which are more than 99.6% aluminum and are also called pure aluminum sheets. They belong to a commonly used series in the aluminum foil strip family. The advantages of this series of aluminum plates include wide application, simple production process, mature technology, and advantageous price. With good elongation and tensile strength, it can fully meet the normal processing requirements (stamping, drawing) and high formability. For industrial pure aluminum, it has high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but its strength is low, heat treatment can not enhance the machinability. 1060 aluminium foil paper strip is the most frequently applied material for dry-type transformer winding.
