High efficiency aluminum alloy refining agent

Aluminium alloy refining agent

Aluminum alloy refining agent is an auxiliary material used in aluminum alloy smelting process, mainly used to improve the composition and properties of aluminum alloy.
The main functions of aluminum alloy refining agent include:
1. Remove oxides and impurities in aluminum alloy to improve the purity and uniformity of aluminum alloy;
2. Adjust the composition of aluminum alloy to meet specific requirements, such as increasing silicon content to improve strength and wear resistance, increasing magnesium content to improve weldability and corrosion resistance;
3. Improve the crystallization properties of aluminum alloy, improve the microstructure and mechanical properties of aluminum alloy;
4. Improve the casting performance of aluminum alloy, reduce the shrinkage of aluminum alloy, porosity and other defects.
Common aluminum refining agents include sodium fluoride, calcium fluoride, aluminum fluoride and so on. These refining agents are usually added to aluminum alloy smelting in the form of powder or block, by reacting with oxides and impurities in the aluminum alloy, so as to achieve the purpose of refining.
The selection and use of aluminum alloy refining agents need to be determined according to the specific aluminum alloy composition and requirements to ensure the best refining results and alloy properties. At the same time, when using aluminum alloy refining agent, attention should be paid to controlling the addition amount and melting conditions to avoid negative effects on alloy properties. Aluminum Alloy Fluxes.Metal Element Additives.Aluminum-based Intermediate Alloys.
