Product Introduction

Transformer aluminum foil is made from high-purity aluminum, typically with a purity of 99.6% or higher, to make sure optimal electrical conductivity and performance. Transformer aluminum foil is characterized by its high mechanical strength, fantastic thermal conductivity, and low weight, making it an ideal material for efficiently transferring electrical energy within transformers. It is typically available in thin, flat sheets or strips that can be easily wound and layered to form the transformer windings. The precise dimensions and thickness of the foil are carefully controlled to meet the specific requirements of different transformer designs. Therefore, transformer aluminum foil plays a crucial role in the efficient and reliable functioning of electrical transformers by facilitating the flow of electricity through the windings.

Product Application

The selection of aluminum foil alloy for transformers involves considering various factors. In terms of electrical conductivity, 1350 aluminum foil offers the highest performance, while 1050, 1060, and 1070 foils provide slightly lower but still satisfactory conductivity. Mechanical strength differs among the alloys, with 1050 having the lowest and 1070 and 1350 exhibiting higher strength. Cost and availability also come into play, as the alloys may vary in terms of pricing and market accessibility. Overall, the choice depends on the specific requirements of the transformer application, with 1350 preferred for superior electrical conductivity, and 1050, 1060, and 1070 offering a balance between electrical properties and mechanical strength, taking into account cost and availability considerations.
