MILL FINISHED ALUMINIUM

Round edge aluminum strip for transformer winding

INQUIRY

The commonly used aluminum grades are 1060, 1050, 1070, 1350, temper O state.

The thickness of strip is usually between 0.2mm-3.5mm.

Can be customized according to customer requirements of different widths and thicknesses.

The aluminum strip features rounded corners or edges, resulting in high conductivity, a smooth, burr-free surface, and high dimensional accuracy.

This aluminum strip is specifically designed for use in the manufacture of high and low voltage transformer windings.

Key Benefits

High Electrical Conductivity

1050 O,1060,O,1070 O, 1350 O

Burr-Free Rounded Edges

Precision slitting and edge-rounding processes ensure the strips are free of burrs, cracks, or roughness. Smooth edges prevent damage to insulation layers and facilitate smooth, tight winding, directly improving transformer performance and efficiency.

Superior Surface Finish

The surface is atomized for enhanced brightness and cleanliness. It is free from corrosion, scratches, dents, waviness, scale, or any other flaws that could compromise reliability.

Excellent Mechanical Properties

Features strong corrosion resistance, good weldability, and outstanding formability, making it ideal for the mechanical stresses of winding.

Technical Specifications

Edge Condition: Rounded, smooth, and burr-free.

Width Tolerance: Precisely controlled to meet required standards.

Flatness: No side bending or waviness.

Surface: Smooth, spotless, and clean.

Packaging: Paper interleaving available upon request to protect the surface between layers during transit and storage.
