1060 Transformer Aluminum Strip Manufacturing and Processing

Item	Description
Production Process	1060 transformer aluminum strip is manufactured through a series of strictly controlled processes, including cold rolling and hot rolling, to ensure mechanical properties and dimensional stability. It is then annealed to improve flexibility and ductility, making it more suitable for transformer winding applications. Finally, it undergoes precise slitting (slit edge) processing to ensure uniform thickness and neat edges, providing a good processing basis for subsequent winding operations.
Edge Treatment	1060 transformer aluminum strip adopts advanced edge processing technology, with a burr-free process that ensures smooth and clean edges, greatly reducing the risk of damage to insulating materials during winding. In addition, the edge processing technology ensures high compatibility with modern automatic winding machines, improving production efficiency and product consistency.
Packaging Method	At the finished product stage, the 1060 transformer aluminum strip is wound on a sturdy paper core with an inner diameter ranging from 150 mm to 500 mm, flexibly configured according to customer equipment requirements. The entire coil is then placed in a reinforced wooden pallet or box to protect the product during transportation and handling, preventing edge deformation or surface scratches, ensuring that each roll of aluminum strip received by the customer is in optimal condition.

1060 Transformer Aluminum Strip vs. Alternatives

Item	Description
Cost Efficiency	1060 transformer aluminum strip stands out in the industry due to its extremely high cost performance. Compared to traditional copper materials, 1060 aluminum strip is more affordable, significantly reducing raw material costs in large-scale transformer production. At the same time, it still provides approximately 61.5% IACS conductivity, meeting electrical performance requirements while effectively optimizing the overall budget, making it a cost-effective alternative to copper.
Thermal Performance	1060 transformer aluminum strip possesses excellent thermal conductivity, enabling rapid heat dissipation during current transmission and effectively suppressing heat accumulation. This thermal property not only helps transformers operate within a safe temperature range but also greatly reduces the risk of insulation material aging caused by overheating, thereby extending the overall service life of the equipment.
Corrosion Resistance	1060 transformer aluminum strip naturally forms a dense layer of aluminum oxide in the air, providing good corrosion resistance. This natural protective layer remains highly stable even in humid, high-salt, or industrial gas environments, allowing it to maintain structural integrity and conductivity under various harsh conditions, thus enhancing the product's long-term durability.

1060 O aluminum strips are the cornerstone of modern transformer manufacturing, balancing performance, affordability, and adaptability. Their high conductivity, precision engineering, and robust packaging make them highly suitable for both dry-type and oil-immersed transformers.
