Aluminium alloy refining agent

There are several types of refining agents used in the refining process of aluminium alloys. These agents are added to the molten metal to remove impurities and improve the overall quality of the alloy. Some common refining agents include:

1. Sodium: Sodium is commonly used as a Refining Agent in aluminium alloys. It reacts with impurities like oxides and forms a compound that can be easily removed from the molten metal.
2. Chlorine: Chlorine gas is sometimes used as a refining agent to remove impurities in aluminium alloys. It reacts with impurities like oxides and forms volatile compounds that can be easily removed from the molten metal.
3. Titanium: Titanium is used as a refining agent in aluminium alloys to remove impurities like oxides and nitrides. It forms stable compounds with these impurities, which can be easily removed from the molten metal.
4. Boron: Boron is another commonly used refining agent in aluminium alloys. It reacts with impurities like oxides and forms stable compounds that can be easily removed from the molten metal.
5. Carbon: Carbon is sometimes used as a refining agent in aluminium alloys. It reacts with impurities like oxides and forms volatile compounds that can be easily removed from the molten metal.
These refining agents are typically added to the molten metal in small quantities and are carefully controlled to ensure the desired refining effect without negatively impacting the alloy's properties.
