Aluminium 7075 Aluminium Cff removes the inclusions in the aluminum melt. It has a significant effect on the strength, fatigue strength, corrosion resistance and stress corrosion cracking performance of the aluminum melt.
Aluminium Cff can effectively control the oxidized inclusions in the melt and improve the quality of cast rods and rolled plates. It has become a common goal pursued by the metallurgical, foundry, and material industries of all countries. At present, filtration and purification methods are widely used to remove inclusions in aluminum alloy melts.
Aluminium Cff can be divided into two categories by size
1. The unevenly distributed large inclusions in the macrostructure make the alloy structure discontinuous, reduce the compactness of the casting, and become the source of corrosion and cracks, thereby greatly reducing the strength and plasticity of the alloy.
2. The fine and scattered inclusions cannot be completely removed after refining. They increase the viscosity of molten metal and reduce the feeding capacity of molten aluminum during solidification.
The secondary oxidation inclusions are mainly formed during the casting process. During the casting process, molten aluminum contacts air, and oxygen reacts with aluminum to form oxide inclusions.
During the smelting process, the aluminum alloy comes into contact with various components in the furnace gas to produce compounds such as AL2O3. Al2O3 in the aluminum melt will increase the hydrogen content in the aluminum melt. Therefore, the content of al2o3 in molten aluminum has a great influence on the formation of pores in aluminum castings.
With the accumulation of this knowledge, the process engineers of the ceramic foam filter China factory can better improve and transform the product quality, and manufacture online degassing devices and CFF devices that meet customer needs.
Therefore, Norwegian Aluminum Company is satisfied with the quality of the ceramic foam filter products of the Chinese factory, and recommends the method of purchasing ceramic foam filters to other casting aluminum companies in Europe sales@alalloycasting.com
