Dongguan Dingfeng Copper and Aluminum Co., Ltd.

Wholesale/retail capillary aluminum tubes Aluminum tubes Hard aluminum tubes can be cut to precise lengths. Dongguan Dingfeng Copper and Aluminum Co., Ltd. is the first choice
Product introduction
Aluminum tubes are a type of non-ferrous metal tubes, referring to Pure aluminum or aluminum alloy is extruded into a hollow metal tubular material along its entire longitudinal length.
Classification:
Aluminum tubes are mainly divided into the following categories:
According to appearance: square tube, round tube, pattern tube, special-shaped tube, and global aluminum tube.
According to the extrusion method: seamless aluminum tubes and ordinary extruded tubes
According to the accuracy: ordinary aluminum tubes and precision aluminum tubes, among which precision aluminum tubes generally need to be reprocessed after extrusion, such as Cold drawing and fine drawing, rolling.
According to thickness: ordinary aluminum tube and thin-walled aluminum tube
Performance: corrosion resistance, light weight.
Characteristics:
It is a kind of high-strength hard aluminum that can be strengthened by heat treatment. It has medium plasticity in annealing, fresh quenching and hot conditions. It has good spot welding properties. It can be used for gas welding and argon arc welding. There is a tendency to form intergranular cracks. The machinability of aluminum tubes is good after quenching and cold work hardening, but poor in the annealed state. The corrosion resistance is not high, and anodizing and painting methods are often used, or an aluminum layer is added to the surface to improve corrosion resistance. Can also be used as mold material.
Advantages of aluminum pipes:
First, the advantages of welding technology: The welding technology of thin-walled copper and aluminum pipes suitable for industrial production is known as a world-class problem and is the key technology for replacing aluminum with copper in air conditioner connecting pipes.
The second is the advantage of service life: from the perspective of the inner wall of the aluminum tube, since the refrigerant does not contain moisture, the inner wall of the copper-aluminum connecting tube will not corrode.
The third is the energy-saving advantage: the lower the heat transfer efficiency of the connecting pipes between the indoor unit and the outdoor unit of the air conditioner, the more energy-saving it is. In other words, the better the heat insulation effect, the more energy it saves.
Fourth, it has excellent bending performance and is easy to install and move
