First, briefly understand the 1350 aluminum alloy

1350 aluminum alloy is an alloy with high aluminum content (at least 99.5%). In contrast, silicon, iron, copper, manganese and other elements are added in very small amounts. It also has other titles: conductive (EC) aluminum alloy, high content aluminum alloy (and 1050 aluminum alloy). Typical characteristics are high conductivity and good formability. Among them, the conductivity of H111 temper is the highest, reaching or exceeding 61.0% IACS. Aluminum foil for transformer winding is generally 1350 aluminum foil; 1350 alloy can be used to make conductors.

Reasons why 1350 aluminum alloy is used in the electrical industry

In fact, not only the 1350 aluminum alloy, but the 1 series aluminum alloy is widely used in the electrical industry. Because the pure aluminum alloy has practically no other metal elements present, the integrity of the naturally-occurring aluminum oxide film will not be damaged, and less corrosion will occur.

Aluminium foil for transformer winding

Aluminum foil for transformer winding alloy is not only 1350 aluminum foil, but also 1050 aluminum foil, 1060 aluminum foil and 1070 aluminum foil.

Similarities between 1350 aluminum alloy and 1050 aluminum alloy

Both are 1 series aluminum alloys, and both can be used for aluminum foil for transformer winding. This is why we compare the two.
Both aluminum contents are at least 99.5%, and have higher conductivity than other 1000 series aluminum. They are the preferred aluminum alloys in the transformer and switchgear market. Because they provide the most economical conductive alloy in the 1000 series. Although there are other aluminum products with higher aluminum content, it is found that most of these alloys are difficult to purchase. And more expensive than 1050, 1350 aluminum alloy.

The difference between 1350 aluminum alloy and 1050 aluminum alloy

There is a specific difference between 1350 aluminum foil and 1050 aluminum foil. In the chemical composition of the two, the maximum silicon content of 1050 is slightly higher than 1350. This is a small difference, they all appear in the form of maximum values, but this small difference may affect critical applications.
