Manufacturing of Aluminum Tube

Packaging of Copper Clad Aluminum Tube

Shanghai Metal Products are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.

1) Shanghai Metal Standard

2) Customization


Applications of Copper Clad Aluminum Tube:

1) Radio Frequency Cable

2) Connection tube

3) Fittings

4) Refrigeration tube

5) Coaxial Cable

6) Inner conductor of RF cable, etc.


The outer layer of CCA tube is T2 or C1100 copper, and the inner layer is antirust 3003 Aluminum Alloy, and the middle layer is the Metallurgy integrated Layer of copper and Aluminum.

Thermal Conductivity for Copper is about 380 W/(m*C), compared to 237 W/(m*C) for Aluminum, which is only approximately 60% of Copper thermal Conductivity.

As aluminum is the material for inner tube, it is better materials to preserve heat than copper.

The weight ratio between copper and aluminum is approximately 55:45, and volume ratio between copper and aluminum is approximately 25:75, with density of 4.3. Compared to copper tubes, it can save up to 45% of the cost. The tensile strength is between 150 and 190MPa, elongation is between 35% and 40%.

Pressure resistance level is above 15MPa. With unique two-layer structure design it has very strong pressure resistance, making it reliable and safer to use.
