  • Product description

Aluminum alloy is a common manufacturing material with excellent mechanical properties, high corrosion resistance and low density, so it is widely used in various industrial fields and daily life. In this paper, the characteristics, application and manufacturing process of aluminum alloy are discussed.


First, the characteristics of aluminum alloy

1. High strength: The strength and mechanical properties of aluminum alloy are very excellent, higher than ordinary steel. This is mainly due to the good composition uniformity of the aluminum alloy itself, which is easy to control the mechanical properties of the final product during processing.


2. Strong corrosion resistance: aluminum corrosion resistance is good, can be used in various environments, will not be oxidized, corroded or corroded. The corrosion performance of aluminum alloy in high temperature, moisture, acid, alkali, salt and other environments is much better than that of steel.


3. Low density: Aluminum alloy has a small density, only about one-third of ordinary steel, and can be made of the same size products with less materials, so it is widely used in aerospace, automotive, electronics and other fields.


4. Good processing performance: The processing performance of aluminum alloy is better, not only can be plastic processing, but also can be hot working, cold working and forging and other ways of processing, can meet the needs of different fields.



Second, the application of aluminum alloy

1. Aerospace: Aluminum alloy has been widely used in the aerospace field, such as the manufacture of aircraft fuselages, engines, propellers, missile navigation systems and so on.


2. Automobile manufacturing: Aluminum alloy is also widely used in the field of automobile manufacturing, such as the manufacture of body, engine, brake system, etc., which can reduce the weight of the car and improve the performance of the car.


3. Electronic devices: Aluminum alloy to make electronic device shell, radiator, etc.


4. Construction field: Aluminum alloy manufacturing building exterior wall panels, sun rooms, etc.



Aluminum alloy manufacturing process

1. Extrusion method: Extrusion method is the most commonly used in aluminum alloy processing. The principle is to process the aluminum rod or aluminum tube into a certain cross-section shape, and then extrude it into the desired shape of the product through a special extruder.


2. Roller method: The roller method is a processing method for preparing strip, that is, the aluminum rod or aluminum strip is bent into the desired width and length of the strip by two rollers rotating each other.


3. Hot extrusion method: Hot extrusion method is a special method for preparing complex shape aluminum alloy materials. The aluminium billet is pre-processed into the desired shape at high temperatures and then extruded into the final shape under high pressure.


4. Cold processing method: cold processing method is a special process for making ultra-thin aluminum alloy sheets, which are processed by rolling, polishing and other ways to produce high-precision sheets.




In short, aluminum alloy is widely used in various industrial fields because of its good physical and chemical properties, good processing performance and low density, and has become an important manufacturing material.
