What are the differences between different types of aluminum tubes

Ordinary aluminum pipe is a pipe type material extruded from an aluminum alloy mold after being heated by an aluminum alloy cast rod at a high temperature.

1. Ordinary aluminum tube. Ordinary aluminum pipes do not undergo any surface treatment. These aluminum pipes are mainly used for outdoor support, machinery, electrical appliances, construction sites and other fields. Material aluminum tubes can be designed with different apertures, different wall thicknesses, and different materials according to product application scenarios and pressure bearing requirements. Jiangyin Chengxing Aluminum Co., Ltd. can extrude aluminum tubes with a diameter of 10~400, the wall thickness can be processed with a thickness of 1.0~50mm, and the material can be processed 6063, 6005.

2. Alumina tube. Alumina tube is a prototype oxidation surface treatment on the basis of ordinary aluminum tube. Alumina tube has relatively high requirements on the product base material, and cannot have slag inclusions, deep mechanical lines, and no scratches that touch and feel. Because these will affect the surface effect after oxidation. Chengxing Aluminum can currently undertake the oxidation of round tubes with a length of 1 to 14 meters. The oxidation processes include ordinary natural color anodizing, black oxidation, sandblasting silver white oxidation, alkali sand oxidation, and acid sand oxidation. The oxidation technology of the round tube is strictly required. Due to its curved surface structure, we must prevent the occurrence of yin and yang surfaces during the oxidation process.

3. Spray aluminum tube. The sprayed aluminum pipes are divided into two types: ordinary powder spraying and fluorocarbon baking paint. The requirements for the aluminum tube substrate of the sprayed product are relatively low, and the slight extrusion lines or fine scratches on the surface of the substrate can be covered by the sprayed powder. For general spraying materials, if the customer has no special requirements, the thickness of the material after spraying can reach more than 40u, which is the national standard. Some customers require special, special use sites, and the thickness of the product after spraying can reach 60u or even higher.

The aluminum alloy pipe has a simple structure, but it is also difficult to produce and process, especially for thin-walled round pipes. In the production process, the control of tolerance accuracy does require a certain amount of technology and experience accumulation. Our representative product, the 300*1.5 aluminum round tube, has an inner and outer diameter tolerance of ±0.5mm. This is a technical challenge among ordinary extruded aluminum tubes.
