Orange peel aluminum coil for refrigerators is an aluminum alloy material with a surface similar to orange peel texture. It is widely used in the heat dissipation, liner, decoration and pipe insulation of refrigerators. Orange peel embossed aluminum coil forms an uneven orange peel pattern on the surface of the aluminum sheet roll through a calendering process, which is both functional and decorative. Its pattern types are divided into classic orange peel pattern and variant orange peel pattern (also known as "worm pattern"). This material has the characteristics of light weight, corrosion resistance, and good heat dissipation. It is one of the indispensable components in refrigerator manufacturing.

Common materials of orange peel aluminum coil for refrigerator:

- 1060 aluminum alloy: pure aluminum material, low cost, suitable for refrigerator heat sinks and decorative panels in ordinary environments.

- 3003 aluminum alloy: contains manganese elements, and its anti-rust performance is better than 1060 aluminum, suitable for refrigerator liner or pipe insulation layer with high humidity.

- 5052 aluminum alloy (special needs): It has stronger corrosion resistance and is suitable for high-demand environments, but is rarely used in the refrigerator field.

Specifications of orange peel aluminum sheet for refrigerator:

- Thickness: 0.15mm–3.0mm (common refrigerator thickness is 0.3–1.0mm).

- Width: 800–1600mm (customizable).

- Surface treatment: Anodizing forms an aluminum oxide film to enhance corrosion resistance, and the surface is oil-free and easy to clean.

Performance advantages of orange peel aluminum coil for refrigerator:

- Lightweight: Aluminum has a low density (2.71g/cm³), which reduces the overall weight of the refrigerator and facilitates transportation and installation.

- Corrosion resistance: The surface after anodizing is acid-resistant and salt-spray-resistant, and is suitable for humid refrigerator internal environments.

- Heat dissipation: Aluminum has excellent thermal conductivity and is often used in refrigerator heat sinks and condenser components.

- Decorative: The orange peel texture reduces light pollution, scatters light more softly, and enhances visual effects.

Application scenarios of orange peel aluminum coil for refrigerator:

- Refrigerator liner and pipe insulation

As a cold storage or refrigerator lining, it provides rust prevention and heat preservation functions to reduce cold air loss.

- Wrap refrigeration pipes to prevent condensate corrosion and improve insulation efficiency.

- Heat dissipation components are used for heat sinks or condenser panels to accelerate heat dissipation and improve cooling efficiency.
