Specifications of Copper Clad Aluminum Tube : 1)Grade:C****0 copper , ***3 aluminum
2)Outside diameter: 6.*5mm**9.*5mm
3)Wall thickness: 0.5mm*1.*0mm
4)Tensile: ******0MPa
5)Elongation: *5%**0%
6)Expanding: >*0%

The outer layer of CCA tube is T2 or C***0 copper, and the inner layer is an antirust ***3 aluminum alloy, and the middle layer is the metallurgy integrated layer (MIL) of copper and aluminum. Thermal conductivity for copper is about **0 w/m*c, compared to **7 w/m*c for aluminum, which is only approximately *0% 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 *5:*5, and volume ratio between copper and aluminum is approximately *5:*5, with density of 4.3. Compared to copper tubes, it allows the customer to save up to *5% of the total cost. The tensile strength is between **0 and **0MPa, elongation is between *5% and *0%. Pressure resistance level is above *5Mpa. With unique two-layer structure design the tube has a very strong pressure resistance, making it reliable and safer to use.
