Precision aluminum tube is a type of aluminum tube. Precision aluminum tubes are divided according to processing methods: cold drawing and fine drawing. Precision aluminum pipe, rolled aluminum pipe, welded pipe. Among them, cold-drawn aluminum tubes have the highest precision, best surface quality and best mechanical properties. Cold-drawn precision aluminum tubes: The raw materials used are extruded aluminum tubes and rolled aluminum tubes. The aluminum tube processed by this processing method has high precision, smooth internal and external surfaces, and the best mechanical properties among the three. Therefore, it is widely used in all walks of life. In Japan, due to the wider use of product technology, even ordinary civilian products are required to be made of cold-drawn aluminum tubes. Such as luggage trolleys, film and television tripods, and heating plates for electric heating equipment.
In modern industry, many products must use cold-drawn precision aluminum tubes, such as oil pipelines for automobiles, aerospace, laser faxes, photosensitive drums in printers, aluminum tubes used for magnetic rollers, etc. For precision For turning parts, in order to reduce the turning allowance and improve the yield, cold-drawn precision-drawn aluminum tubes have also attracted much attention and use.
Welded pipe: There are relatively strict requirements for the thickness of aluminum plates and aluminum coils, and the pattern requirements are fine. It is a relatively small or thin type of aluminum tube. It is generally used in pen tubes, jewelry holders and other small objects. The following takes the specifications of aluminum tubes from a factory as an example:
1. Aluminum plate thickness.3-width,
2. Aluminum coil: thickness.width
3. Patterned aluminum plate: five-striped willow leaf type, pointer Type or customized thickness
4. Bar: extruded round bar (R,) state: diameter is ~ quenching state: diameter is ~ (,,) extruded square, regular hexagonal bar state: inscribed circle diameter It is ~ quenched state: the diameter of the inscribed circle is ~ extruded rectangular rod (flat rod) width: ~ thickness: ~
5. Pipe material:,,,,,,,,,, extruded seamless round tube ( Flat tube, square tube, oval tube, harmonica tube) outer diameter range: ~ wall thickness range: ~, drawn tube outer diameter range: ~ wall thickness range:. ~
Aluminum pipe material type: 3/,< br/> Specifications: outer diameter 3 wall thickness
