1050 Aluminum Foil Technical Parameter

Applications of 1050 Aluminum Foil

Used for transformer winding:

The aluminum foil used for transformer winding is required high-quality pure aluminum as raw material which has high conductivity, soft characteristics, and smooth surface, is an ideal material for the production of dry-type transformers and is the key raw material for transformer winding.

Designers of transformer manufacturing usually select 1050,1060,1070,1350 grades, the aluminum content is min 95% but commonly above 99.6%-99.7 %. Aluminum sheet foils are mainly used in dry-type transformers of high and low-voltage winding as the conductive material. As aluminum transformers tend to be less costly than copper transformers, therefore, aluminum foil is the most popular material for the transformer strip.

1050 Aluminum Foil Quality

The surface of the aluminum foil should be clean, and smooth. There is no corrosion, empty, folding, brown staining, slotted, add edge, wrinkling, concave and convex.

The surface of the aluminum foil is not allowed to have a serious color difference.

The end surface of the aluminum foil should be clean and tidy, there is no burr, wrong layer, bruising, or collapse.
