Advantages and disadvantages and application of 4 series aluminum plate
The 4 series aluminum plate is an aluminum plate with silicon as the key alloy element, that is, aluminum-silicon alloy. The 4-series aluminum plate is used more abroad, but less in China. In terms of production technology, the level of domestic aluminum-silicon alloys is very different from that of Western countries. Characteristics of 4 series aluminum plate 1. High wear resistance. Aluminum-silicon alloys have high wear resistance. With the increase of silicon content, the strength and compressive strength of aluminum-silicon alloys will increase. 2. The coefficient of linear expansion is small. All raw materials will swell at high temperature, which limits the application scope of most raw materials. The Al-Si alloy has a small coefficient of linear expansion and can work in a high temperature natural environment. 3. Easy to forge. Among the forged aluminum alloys, the 4-series aluminum-silicon alloy accounts for more than 90%, which shows the excellent forging performance of the aluminum-silicon alloy. The defects of aluminum-silicon alloys have not been properly dealt with at this stage 4 series aluminum plate The advantages and disadvantages of 4 series aluminum plate and its application Defects of 4 series aluminum plate 1. When the silicon content is low, the specification...
