Shanghai Metal Corporation is a leading Copper Clad Aluminum Tube (CCA Tube for Radio Frequency Cable) manufacturer and supplier.
Copper clad aluminum tube (CCA tube) ,Its characteristics are: the outer layer of the tube is copper, the inner layer is aluminum alloy, and the weight of copper accounts for 53%±3% of the weight of the pipe. The heat exchange and connecting pipe of air conditioning, refrigerator, freezer, air source water heater, hot and cold water machine, etc which always use copper tube and internal threaded tubes. However, the price of copper ingots is high, and the CCA pipe has better replaced the copper pipe. The national standard of copper-clad aluminum pipe can provide the guarantee of pipe raw materials for the air-conditioning and refrigeration manufacturing industry.

1) Shanghai Metal Standard
Applications of Copper Clad Aluminum Tube:
1) Copper Clad Aluminum Tube for Radio Frequency Cable
2) Copper Clad Aluminum Tube for Connection tube
3) Copper Clad Aluminum Tube for Fittings
4) Copper Clad Aluminum Tube for Refrigeration tube
5) Copper Clad Aluminum Tube for Coaxial Cable
6) Copper Clad Aluminum Tube for 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.
