Articles & Magnesium News

During the last few decades the world has seen rapid growth in the application of magnesium and its alloys almost in every field of today's industry.
Applications of high-temperature magnesium granular alloy are really important for nowadays metallurgy and engineering. A big part of people's business relies on magnesium and its properties. This is due to numerous characteristics of the metal, which permit its use both as a structural element, and as a chemical addition to other metal alloys. Among all structural metals on the market today, magnesium is the lightest. It's a construction material in the automobile industry, specifically wheels and forged pistons for high-powered internal combustion engines. The granular alloy with improved mechanical properties can endure temperature operating conditions for a long time at a temperature up to 350 C and for a short time at a temperature of 400 C.
As the metal magnesium is the third most commonly used structural metal, following steel and aluminum. Magnesium compounds, primarily magnesium oxide, are used mainly as refractory material in furnace linings for producing iron, steel, glass, cement and nonferrous metals. Magnesium oxide and other compounds also are used in agricultural, chemical and construction industries. Magnesium, in its purest form, can be compared with aluminum, and is strong and light, so it is used in several high volume part manufacturing applications. Today high-grade car wheels of magnesium alloy we called 'mag wheels'. New alloy development and lower costs, which are becoming competitive to aluminum, will further the number of automotive applications. Interesting situation is in December 2005, for the first time on record, the automotive grade magnesium alloy price per cm dropped below the A380 aluminum alloy price per cm.
Due to low weight, good mechanical and electrical properties, magnesium is widely used for manufacturing of mobile phones, laptop computers, cameras, and other electronic components. So, electronic devices of the metal are very important, too. Also the use of magnesium alloys in aerospace is increasing, mostly driven by the increasing importance of fuel economy and the need to reduce weight.

What is magnesium?

Green vegetables such as spinach provide magnesium because the center of the chlorophyll molecule contains magnesium. Nuts (especially cashews and almonds), seeds, and some whole grains are also good sources of magnesium.

Notable features

Magnesium is a fairly strong, silvery-white, light-weight metal. It is protected by a thin layer of oxide which is fairly impermeable and hard to remove. Magnesium reacts with water at room temperature, though it reacts much more slowly (for example) than calcium.
