Zinc Diffusion Aluminum Tube

 

Our zinc diffusion aluminum tubes are engineered for exceptional corrosion resistance and long service life, making them ideal for high-durability heat exchanger applications. The zinc diffusion treatment forms a protective layer that significantly enhances the tubes' resistance to atmospheric and fluid corrosion, extending their operational lifespan under harsh conditions. Crafted from high-Quality Aluminum alloys, they maintain excellent thermal conductivity and mechanical strength, ensuring efficient heat transfer while withstanding long-term pressure and temperature fluctuations. This design reduces maintenance frequency and replacement costs, offering a cost-effective solution for demanding thermal management systems.

 

 

These tubes are available with outer diameters ranging from Ø5 to Ø25.4 mm and wall thicknesses of 0.3 to 2.5 mm, using base alloys such as 3003, 3103, and AA003. The zinc spraying amount is controlled between 4 to 14 g/m², with a zinc penetration depth of 0 to 500 μm, creating a uniform protective layer. The precise treatment process preserves the tubes' structural integrity and thermal performance, while strict dimensional tolerances ensure seamless integration with standard heat exchanger components.

 

 

Widely used in high-durability heat exchanger systems, these zinc diffusion aluminum tubes are perfect for household air conditioning condensers, commercial air conditioning condensers, and air source water heaters. They are specifically designed for applications requiring extended service life, reliably operating in residential, commercial, and industrial thermal management environments to deliver consistent performance over long periods.
