Transformer aluminum foil is a key component of insulation and conductivity in the transformer, which directly affects the quality of the transformer. Transformer aluminum foil and strips generally use 1060 aluminum foil, 1070 aluminum foil and 3003 aluminum foil, which belong to the conventional series in the aluminum strip family. 1 series and 3 series aluminum plates are ordinary aluminum plates and have a price advantage over 5 series and 6 series products. The thickness of aluminum foil for transformers is generally between 0.02-0.055mm.
Transformer foil is manufactured using a specialized rolling process to achieve the required thickness and mechanical properties. Foils can undergo additional treatments, such as annealing, to improve their ductility and conductivity.

Hydrophilic coated aluminum foil is a composite material based on aluminum foil. It has good heat dissipation properties of ordinary aluminum foil, and also has corrosion resistance and hydrophilicity that ordinary aluminum foil does not have. It is a substitute for ordinary aluminum foil used in air-conditioning heat exchangers. product. MC Aluminum can provide blue hydrophilic aluminum foil and gold hydrophilic aluminum foil.
Hydrophilic aluminum foil is hydrophilic treatment of aluminum foil. After special processing, the surface is coated with a hydrophilic layer. Condensed water will spread quickly on the hydrophilic aluminum foil and will not condense into water droplets, thus increasing heat exchange. area, speed up cooling and heating, and effectively avoid noise caused by condensed water blocking the air flow.
Hydrophilic aluminum foil usually uses alloy numbers: 1100, 1200, 8011, 1030, etc.
Advantages of hydrophilic coated aluminum foil:
1. Excellent hydrophilicity, corrosion resistance, high temperature resistance, and mildew resistance;
2. Good formability and no wear on the mold;
3. Improve heat exchange efficiency; the heat exchange rate can generally be increased by 10%-15%.
4. Easy to clean and maintain;
5. Wide range of uses, suitable for food packaging, pharmaceutical packaging, cosmetic packaging, aluminum fins and other fields;
Color-coated aluminum foil is an aluminum foil product whose surface has been painted or coated. The performance of aluminum foil is very stable, and the paint can be used for several years without fading. Color-coated aluminum foil has the characteristics of water resistance, steam resistance, light resistance, taste resistance, corrosion resistance, heat resistance, low temperature resistance, etc., and is not easily affected by the environment and temperature. Therefore, it is often used in food, medicine, beverages, cosmetics, spices, etc. to prevent items from absorbing moisture, oxidation, volatilization and deterioration.
When aluminum foil is placed in the air, a dense oxide layer forms on the surface. If the oxide layer is not dirty, the ink will have good adhesion to it. In order to improve the adhesion between the ink and the aluminum foil surface, corrosion cleaning must be performed before printing. Coating treatment eliminates lubricant contamination and enhances the adhesion between ink and aluminum foil surface.
When performing color printing, since the aluminum foil paper itself has color, in order to ensure the correct restoration of the ink hue, the background color must be printed before printing, and the background color is usually white ink.
Color-coated printed aluminum foil commonly uses 1000, 3000, and 8000 series alloy numbers, including 1100, 1070, 3003, 3004, 8011, 8021, 8079 and other alloy numbers.
Color printed aluminum foil is suitable for a variety of industries, including the food and beverage industry, pharmaceutical industry, personal care and cosmetics industry. The foil is printed using high-quality rotogravure and flexo printing, giving the packaging a vibrant appearance.
Hongchang Aluminum is a professional aluminum foil manufacturer specializing in the production of 1-8 series aluminum foil, including printed aluminum foil, colored aluminum foil, packaging aluminum foil, insulating aluminum foil, etc. The product range is complete and the specifications can be customized according to customer needs.
Household aluminum foil is mainly used for cooking and decoration. In terms of cooking, aluminum foil can be used to store food, cover baking surfaces, wrap meat and other foods to prevent them from losing moisture while cooking, it can also be used to line baking sheets to keep things tidy, or for scrubbing dishes or baking dishes. rack to remove stubborn stains and residue.
Household aluminum foil is also called aluminum foil, kitchen aluminum foil, and food packaging aluminum foil. It is produced from raw material aluminum ingots through main processes such as casting, cold rolling, foil rolling, slitting, and annealing. It has excellent performance and stable quality.
Household foils usually use 1235 aluminum foil and 8011 aluminum foil, which have the advantages of food grade, flat plate shape, clean surface, no oil stains, bright lines and other inclusions, safe and hygienic products, and high elongation rate.
Performance advantages of household aluminum foil:
Aluminum foil food packaging is beautiful, lightweight, easy to process, and easy to recycle;
1. Aluminum foil is non-toxic, tasteless, safe and hygienic
2. Excellent barrier properties, strong air barrier properties, antioxidant, waterproof, and moisture-proof; helps maintain the aroma of food and keeps food fresh for a long time.
