Basic Knowledge of Magnesium

What is Magnesium?

Magnesium, discovered in 1808 by Sir Humphry Davy, is known through compounds like Epsom salts, magnesia, and magnesite. The name comes from Magnesia in Greece, where magnesia alba was first found. It is the eighth most abundant element in Earth’s crust and a common structural metal after aluminum and iron. Magnesium is found in carbonates and silicates, as well as in minerals like talc and olivine. It is commercially produced through the electrolysis of molten magnesium chloride or by directly reducing its compounds.

Magnesium burns with a bright light, making it historically used in photography and still employed in pyrotechnic devices. It has similar thermal and electrical conductivity to aluminum. Magnesium is resistant to alkalies, but when magnesium comes into contact with acids, it reacts with them, releasing hydrogen gas and other chemical changes in the magnesium material. Magnesium forms a protective oxide layer in air and water but reacts with steam. It acts as a powerful reducing agent to produce other metals like titanium and zirconium and reacts directly with many elements.

Machining Magnesium Buying FAQ

Magnesium has an impressive strength-to-weight ratio. While it is not as strong as some other materials like steel, its strength is used in applications where weight reduction is needed. The strength of magnesium can be further enhanced through alloying and specific heat treatment processes.
Quality is ensured through rigorous inspection processes, including in-process inspections, final inspections, and the use of advanced measurement tools and equipment.
To provide an accurate quote, we need detailed drawings or CAD files, material specifications, quantity, desired tolerances, surface finish requirements, and any special instructions or considerations.
Magnesium itself is not explosive, but it is highly flammable. In certain conditions, such as fine powder or shavings, magnesium can ignite easily and burn with a bright, intense flame. Solid magnesium in standard forms used in manufacturing and structural applications is not explosive. However, precautions must be taken when working with magnesium to prevent ignition and fires, especially when flammable materials are present.
