Magnesium alloys hadn't been used in automotive bodies because of their poor formability and low strength, but the research team developed the new age-hardenable magnesium alloy by adding very small amounts of zinc, manganese, aluminum and calcium.

Is magnesium used in car bodies?
Structural, body and engine parts made of magnesium have been used on automobiles since the 1930s. Magnesium is 75 percent lighter than steel and 33 percent lighter than aluminum, but current vehicles utilize only less than 1 percent magnesium on average.
Is magnesium important for making cars?
Magnesium has several intrinsic properties that make it a great choice in the automotive industry. First, it is the lightest of all structural metals––it is 33% lighter than aluminum and 75% lighter than steel. Extruded magnesium, in particular, is known for its high specific strength, stiffness, and durability.
Why are car manufacturers using magnesium instead of iron?
Magnesium is an attractive material for automotive use, primarily because of its light weight - 36% lighter per unit volume than aluminum and 78% lighter than iron. When alloyed, Mg has the highest strength-to-weight ratio of all the structural metals. ... Magnesium is abundant.
Is magnesium better than aluminum?
Magnesium is extremely light: it is 75% lighter than steel, 50% lighter than titanium, and 33% lighter than aluminium. It has the highest known damping capacity of any structural metal, capable of withstanding 10x more than aluminium, titanium, or steel.
Are car engines made of magnesium?
'The heaviest part of a car is its engine, and the engine block makes up to 20-25% of the engine weight. Developing a magnesium alloy that can be used in the high-temperature conditions found in modern car engines has been the goal of researchers for many years.
How much magnesium is in a car?
Schultz said the average passenger vehicle on the U.S. market has a weight of about 3,800 pounds, including 10 pounds from magnesium. Steel makes up 2,100 pounds of the weight of that average vehicle, and aluminum makes up 343 pounds.
Why is China not producing magnesium?
China has slowed down its magnesium production due to the power crunch. A magnesium scarcity would impact many industries, including car-making and drinks cans.
Is there a global magnesium shortage?
To add insult to injury, there is a worldwide shortage of magnesium, which is a vital material to making cars. Without it, many parts can't be produced. China is the world's primary magnesium supplier and the country is currently unable to export it due to an energy crisis.
Is magnesium a metal?
A silvery-white metal that ignites easily in air and burns with a bright light. Magnesium is one-third less dense than aluminium.
How much is magnesium metal worth?
The current price of magnesium metal (99.5% ingot) is approximately $2,250 per tonne versus MgO (DBM 95%) at approximately US$600 per tonne.
Is magnesium mined?
Magnesium is chiefly obtained by electrolysis of magnesium chloride, which can be obtained in virtually unlimited quantities from the oceans. ... Magnesium is mined in China, North Korea, Russia, Austria, Greece and the USA.
What is unique about magnesium?
Magnesium is the 11th-most abundant element in the human body by mass. Magnesium ions are found in every cell in the body. Magnesium is necessary for hundreds of biochemical reactions in the body. ... Magnesium is the eighth-most abundant element in the Earth's crust.
What cars have magnesium engine blocks?
Audi, Daimler (Mercedes-Benz), Ford, Jaguar, Fiat and Kia Motors Corporation are just a few of these companies. Magnesium is currently being used in gearbox, front end and IP beams, steering column and driver's air bag housings as well as in steering wheels, seat frames and fuel tank covers.
What is the weakness of magnesium?
Another more specific sign of magnesium deficiency is muscle weakness, also known as myasthenia ( 18 ). Scientists believe the weakness is caused by the loss of potassium in muscle cells, a condition associated with magnesium deficiency ( 19 , 20 ).
Why is magnesium so expensive?
Magnesium is still, however, limited by its extractions costs, which make the metal about 20% more expensive than aluminum. Due to import tariffs on Chinese-produced magnesium, US magnesium prices can be almost double that of aluminum.
