1050 1070 Aluminum for Dry-Type Transformers - High Quality Electrical Conductivity

Characteristics of 1050 Aluminum

• High Purity: 1050 aluminum has a high purity level, with aluminum content typically reaching 99.50%. This high purity contributes to its excellent electrical conductivity, which is crucial for reducing power losses in transformers.
• Good Thermal Conductivity: It possesses good thermal conductivity, allowing for efficient heat dissipation. In transformers, this helps to prevent overheating and maintain stable operation, thus prolonging the service life of the transformer.
• Excellent Formability: 1050 aluminum is highly formable, making it easy to process into various shapes and sizes required for transformer components, such as winding wires and heat sinks.
• Corrosion Resistance: It has a certain degree of corrosion resistance, which can protect the transformer components from environmental corrosion and ensure the reliability of the transformer in different working environments.

Characteristics of 1070 Aluminum

• Even Higher Purity: 1070 aluminum has an even higher aluminum purity, usually up to 99.70%. This extremely high purity results in even better electrical and thermal conductivity compared to 1050 aluminum, further reducing energy losses in transformers.
• Superior Ductility: 1070 aluminum has excellent ductility, enabling it to be drawn into very fine wires without breaking. This is particularly advantageous for manufacturing transformer windings, where thin and long wires are often required.
• Good Weldability: It has good weldability, which facilitates the assembly of various transformer components. The welded joints have high strength and reliability, ensuring the structural integrity of the transformer.
• High Purity Corrosion Resistance: Due to its high purity, 1070 aluminum has outstanding corrosion resistance, making it suitable for use in harsh environments where the transformer needs to withstand severe weather or corrosive substances.

Applications in Aluminum Transformers

• Transformer Windings: Both 1050 and 1070 aluminum are widely used to make transformer windings. The high electrical conductivity of these alloys reduces the resistance of the windings, thereby minimizing copper losses and improving the efficiency of the transformer. The good formability and ductility allow the aluminum wires to be wound precisely and neatly around the transformer core.
• Heat Dissipation Components: In transformers, heat generation is a common issue that needs to be addressed. The good thermal conductivity of 1050 and 1070 aluminum makes them ideal materials for manufacturing heat sinks and other heat dissipation components. These components can quickly transfer the heat generated by the transformer to the outside, maintaining the normal operating temperature of the transformer.
• Structural Components: The excellent formability and corrosion resistance of these two aluminum alloys make them suitable for manufacturing some structural components of transformers, such as transformer casings and brackets. These components not only provide mechanical support but also protect the internal components of the transformer from external damage and corrosion.
