1050 transformer aluminum strip foil belongs to pure aluminum, with an aluminum content of more than 99.5%. 1050 aluminum strip has the characteristics of high plasticity, good corrosion resistance, high electrical conductivity and thermal conductivity, but it has low strength, not strengthened by heat treatment, poor machinability, and can be accepted for gas welding, argon arc welding and spot welding. 1050 – O/HO aluminum foil strip for transformer winding, also known as 1050 aluminum transformer strip foil, mainly used for dry type and oil-immersed transformer winding. The thickness ranges of 1050 aluminum foil strip for transformer from 0.2mm to 3.00mm and width ranges from 10mm to 1500mm.
Flait Aluminum is a professional manufacturer of aluminum strips for transformers. We have multiple aluminum strip slitting production lines, and can customize the width and length of aluminum strips according to customer requirements. The 1050 O/HO transformer aluminum strip foil has a smooth surface without scratches, and the edge chamfer can reach 100% without burrs, resistivity and conductivity are better than the national and industry standards for transformers.
