What is the difference between the seamless aluminum tube and the conventional aluminum tube extrusion process?
the seamless aluminum tube is a perforated extrusion method, and the conventional aluminum tube is generally used in combination die extrusion. The short rod, high temperature, slow extrusion process, especially to control the "three temperature", aluminum rod, extrusion cylinder, and the mold must be kept clean, aging time and temperature are adjusted according to the wall thickness of a size can, research focus in aluminium alloy seamless pipe, special aluminum industrial products and professional production. The products are characterized by high technical content, flexible batch specifications and high added value. The high strength Aluminum Alloy seamless tube is the company's specialty products, such as pipe with seamed tube than organization seamless tube has more uniform properties, low resistance, can withstand higher loads and internal pressure. The brands are: 1050, 1060, 1070, 2A11, 2A12, 2A14, 2A50, 2017, 2024, 3003, 4032, 5056, 5A02, 5083, 6061, 6063, 6A02, 6063, 6063 7A04, 7A09, etc.
Seamless Aluminum tubes can be ordered in all available alloys. Using a number of different container sizes on our mandrel piercing extrusion presses, we cover a large spectrum of dimensions. Tubes having a smaller outside diameter or a thin wall are drawn to the final dimension. Please refer to the charts for our dimensional capability.
Another reason for the drawing of the tubes can be a requirement for very tight dimensional tolerances. For alloys whose strength is achieved by work hardening, we can offer the required temper by cold drawing to final dimension. Do you want to form the tubes into a different shape? By a carefully controlled sequence of drawings and heat treatments, we achieve a fine, uniform grain structure. With these tubes you can reach maximum deformation in processes such as bending and shaping.
Sometimes the tubes or profiles are required in short fixed lengths rather than long or random lengths. This opportunity is provided by our associated sawing mill. Depending on the dimension of the tube we can offer various surface finishes. We can offer grinding, polishing or honing, to bring the outside and inside surfaces to the desired quality.
We also produce other than round tubes. If you are interested in square or rectangular tubing, please contact us for further information.
Many of our products are used for Aerospace applications such as actuator rods, drive shafts, aircraft door and seating components, fluid systems (high and low pressure) and ejector seat frames to mention just a few. All of these applications are very demanding and are produced in a number of medium (6xxx, 5xxx) and high strength (2xxx, 7xxx) aluminium alloys. They are required to meet stringent Aerospace Material Specifications which include requirements for surface quality, dimensions and tolerances, mechanical properties and in most cases, a number of special testing requirements (e.g. Eddy Current Testing, Electrical Conductivity Testing, Ultrasonic Testing and Susceptibility to Corrosion Testing etc.). The critical parameters of each manufacturing process are controlled and monitored for each order item produced. Many of the products require heat treatment in order to achieve their final properties. The heat treatment process is performed in accordance with the applicable material specification (e.g. AMS 2772) in ovens meeting the requirements of AMS2750.
Is the aluminum ingot ingot into container, adding to pressure on the aluminum axis through the crowded, make it from a given shape and size of die hole in extrusion, plastic deformation and to obtain the required a processing method of extrusion products.
Metals flow in different directions when pressed.
Extrusion can be divided into forward extrusion, reverse extrusion and joint extrusion.
In the forward extrusion, the moving direction of the extruded shaft is in line with the flow direction of the extrusion metal, while in the reverse extrusion, the moving direction of the extruded shaft is opposite to the flow direction of the extrusion metal.
According to the heating temperature of billet, extrusion can be divided into hot extrusion and cold extrusion.
The hot extrusion is to heat the billet to the recrystallization temperature. The cold extrusion is extruded at room temperature.
7075-T6 Aluminum Tubing is a high strength alloy with good resistance to stress corrosion cracking. Since its introduction, it has been the mainstay of the aviation industry. Aluminum 7075 brings moderate toughness and excellent strength to weight ratio. It is also worth noting that the strength of the 7075 aluminum alloy increases at sub-zero temperatures.
