What is Magnesium cored wire and its Uses?
A type of wire called magnesium cored wire has magnesium in the middle and a steel sheath around it. This design makes it possible to add magnesium to liquid metal in a controlled way during different metalworking processes. Usually, the wire is put into liquid metal. The magnesium core melts and mixes with the metal, which has certain benefits. What Magnesium Cored Wire Is Used For: Steel Desulfurization: - Magnesium is very good at lowering the sulfur level of steel. Steel can become weak and less durable when sulfur is added. When magnesium-cored wire is put into liquid steel, it combines with sulfur to make magnesium sulfide (MgS), which is easy to get rid of. Nodularization in Ductile Iron Production: - Adding magnesium to cast iron helps spheroidal graphite (nodules) form, which makes the iron stronger and tougher. The magnesium in the cored wire supports the formation of nodular graphite instead of flaky graphite, leading to malleable (or nodular) iron. Inoculation of Iron:
