pecifications of Copper clad aluminum tube

 
Copper Clad Aluminum (CCA) tube is similar to Aluminum Clad Copper (ACC) tube, developed after ACC tube, its used for air conditioner tubes, insulated connection pipe in refrigerators and heat exchange area, and Radio Frequenc (RF) coaxial cable.
 
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.
