Aluminum alloys containing more than 2 % magnesium become brittle with sodium.
sodium removering flux is a compact covering and cleaning granulated flux to remove the sodium in the aluminum melting. It generates low dust and low fume during application. It reacts quickly with molten aluminum and removes the alkali metal (Ca, Na, Li, Sr) and non-metallic inclusions (oxides, carbides, borides) and degassing.
1. Do not contain various forms of Na, which is suitable for Mg>2% al-alloy to avoid “sodium brittle”
2. The main components are Chloride and Fluoride salts with other salts and compounds.
3. The dry raw materials are mixed together and then are fused or melted into a liquid state by usIng a high temperature furnace.
After fusing completed the flux are cooled and they are crushed or ground into ccustomerized particle size.
