Product Details ofAluminum Strip for Transformer
Amazing aluminium strip manufacturing process, from the best -- HWALU
Aluminium Strip Description
Aluminum strip coil for transformer is also known as transformer foil strip or transformer foil, which are mainly used in the dry type and oil-immersed transformers winding. It usually ranges from 0.1mm to 3.5mm in thickness and 10mm to 1600mm in width .
HWALU transformer aluminum strip is made of high-quality pure aluminum, with a smooth surface without burrs, no scratches or impurities, with high conductivity and soft texture. We can supply transformer strips in 4 different conditions, ensuring proper yield and tensile strength, elasticity and hardness values for the required solution

Advantages of HWALU Transformer Aluminum Strip
1. Starting from the aluminum strip casting process, strictly control the process flow of casting, rolling, heat treatment and finished product shearing, control the alloy composition, optimize the rolling and annealing process, and make the product achieve high electrical conductivity and mechanical properties.
2. It has good elongation and tensile strength, can meet the requirements of conventional processing (stamping, stretching), and has high formability.
3. The technology is relatively mature, and it has a huge advantage in price compared with other high-grade aluminum alloys.
4. It has good corrosion resistance, electrical conductivity and thermal conductivity.
