Al-Al composite tube, making an additional layer of weldable aluminum smoothly attach to the ordinary tube. Generally, the internal material is 3003 or 6061, and the external layer is 4343 or 6063, so the two kinds of aluminium alloy are closely joint together. The additional layer makes tubes can be welded with other materials. This kind of composite aluminum tube is widely used as a

High-Frequency Welded Aluminium Flat Tube is widely used in the heat exchanger of auto radiators, intercoolers and oil coolers, the radiator of the engine cooling system, the heater or air conditioning system.
So does aluminum alloy seamless collector tube (base material is 3003 or 6063). The brazing material is 4045 or 4343, which is 5 percent -10 percent of the total thickness. The feature is uniformity, high bursting pressure and the stable quality of the heat exchange.

Aluminium has a lightweight and high strength-weight ratio. Since aluminum provides about three times as much volume of metal per pound as steel products, it is the obvious choice when weight is a critical factor.
Aluminum is non-toxic. Excellent resistance to corrosion permits its use without protection in most environments.
