A magnesium ingot is a solid block of metallic magnesium, typically cast into a standardized shape such as a rectangular or square block. It is primarily produced for transportation, storage, and further processing into various products. Magnesium ingots are known for their lightweight nature and high strength-to-weight ratio, making them ideal for use in many industrial applications. Due to its reactivity, magnesium is often alloyed with other metals to enhance its properties.
Key Properties of Magnesium Ingots:
Appearance Silverywhite metallic blocks often rectangular or trapezoidal
Lightweight Magnesium is the lightest structural metal with a density of about 174 gcm
Corrosion Resistance Moderate in its pure form but improves significantly when alloyed
High Strength to Weight Ratio Ideal for applications requiring structural integrity without added weight
Machinability Easy to machine mold and process
Production of Magnesium Ingots
Raw Material Extraction Magnesium is extracted from ores such as dolomite or magnesite or recovered from seawater or brines
Smelting and Refining The extracted magnesium is melted and purified
Casting into Ingots Molten magnesium is poured into molds to form ingots of specific shapes and sizes
