ALLOY 1350

High content aluminum alloys, such as alloy numbers 1050 and 1350, are also known as having a high EC (Electrical Conductivity). These alloys contain a minimum of 99.5% aluminum and are more electrically conductive than other 1000 series aluminum. These are the preferred aluminum alloys in the transformer and switchgear markets, as they offer the most economical conductivity in the 1000 series. Although other aluminum items have higher aluminum content, most find those alloys as difficult to source and are exponentially more expensive than the 1050 and 1350 alloys.

Aluminum alloys 1050 and 1350 do have one specific difference in where the chemical composition of 1050 has a slightly higher max on its silicon content than 1350. It is a very small difference and they are both present as maximum values, but the small difference could affect critical applications.
