1350 Aluminum Strip for Transformer

1350 aluminum strip is a commonly used electrical grade aluminum material for transformer winding and other conductor applications. It offers excellent electrical conductivity, good ductility and stable processing performance. Because of its conductor-grade characteristics, 1350 aluminum strip is widely selected by transformer manufacturers for coil winding where reliable electrical performance and smooth winding operation are required.

For transformer winding applications, 1350 aluminum strip is usually supplied in O temper / soft temper. The soft condition allows the strip to be bent and wound smoothly during coil production, reducing the risk of cracking, deformation and insulation damage.

Our 1350 aluminum strip for transformer winding is produced through controlled rolling, annealing, precision slitting and strict quality inspection. We can supply customized thickness, width, coil inner diameter, edge condition and packaging according to customer requirements.

Note: Chemical composition is for reference only. Final data may vary according to applicable standard, production condition and customer technical requirements.

Typical Mechanical Properties:

Note: Mechanical properties may vary depending on thickness, width, annealing process and production standard.

Electrical Conductivity:

Note: Conductivity values are reference data. Specific conductivity requirements can be tested and confirmed according to customer application.

Thickness and Width Tolerance:

Note: Tolerance can be customized according to actual specification and technical agreement.

For transformer winding, edge quality is very important. Poor edge condition may damage insulation paper, insulation film or other insulating materials during winding. Therefore, transformer winding aluminum strip requires strict burr control and stable edge quality.

Note: Special edge requirements can be discussed according to customer winding process and drawings.
