The importance of aluminum rare earth alloys in aluminum alloy smelting
Aluminum rare earth alloys play an important role in the smelting of aluminum alloys. Adding an appropriate amount of aluminum rare earth alloys can improve the shape of inclusions, purify grain boundaries, and also change the fluidity of the alloy. Tests have proved that aluminum rare earth alloys can reduce the alloy solution. The surface tension has the functions of degassing and impurity removal, and can also improve the fluidity of the solution and reduce the viscosity.
Aluminum rare earth alloys have a refining effect on aluminum alloys, thereby inhibiting the growth of columnar crystals and double columnar crystals, and promoting the formation of fine axial crystals. This is the grain refinement treatment. The refined aluminum alloy performance will be improved, and at the same time, the defects such as loosening, hot cracking and pinholes of the aluminum alloy can be reduced, and the range of use can be increased.
Adding an appropriate amount of rare earth to the aluminum alloy can not only play the role of grain refinement, but also significantly refine the dendritic structure, and only under a certain production process can it achieve a good refinement effect. The refined aluminum alloy properties will continue to change, can be used in domestic industrial production, and outstanding performance.
Aluminum rare earth alloys have good long-term performance and resolubilization stability, low inhalation tendency, no pollution, simple addition to the public, and will not cause any corrosion. After adding the aluminum rare-earth alloy, it must be sampled and tested every time, and it must be remelted five times. It needs to be added at high temperature, so that the aluminum alloy solution will be more pure and can play a better role.
The aluminum rare earth alloy produced by our company adopts new technology, so that the quality of the aluminum alloy can be guaranteed, and it can be widely used in aerospace, machinery manufacturing, energy transportation, electronic communications and other industries. Our company has many years of smelting technology and advanced equipment, so customers can rest assured to choose.
