There is concern over the use of an ingredient in fireworks (magnesium) to create lightweight parts for a car, sporting equipment, medicine, etc. True, magnesium reacts to fire with very bright and extremely high heat flame. It can also have an explosive reaction with water. The explosive nature of the metal has naturally given the magnesium alloy a misguided reputation of exploding while in use in a car or piece of aerospace equipment. Engine parts made of magnesium alloys have been the most unfortunate, as engines are known to get extremely hot from normal operation.
How NOT to start Film Noir Cinema In Greenpoint a magnesium fire
The high heat from the engine is also a concern for car buyers. As the engine runs, it reaches very high temperatures. Dust and shavings from the magnesium cast block can potentially ignite in such an environment. However, the cooling systems built into the cars using the magnesium engines prevent the high heat from becoming an issue. Proper maintenance can catch a problem that will produce metal shavings before they become a fire hazard as well.
However, magnesium alloys do not ignite unless exposed to flame or heat that is much hotter than that produced by a working engine. The metal burns at temperatures in excess of 3,600 degrees Fahrenheit or 2,000 degrees Celsius. However, the magnesium is not a metal that ignites when in the air. Furthermore, you can’t start a fire by throwing water on a magnesium engine. The fire must be ignited in order to cause the magnesium to burn.
Putting out magnesium fires
It is true that magnesium does cause the hydrogen and oxygen molecules in water to combust, only adding to the fire. To extinguish a magnesium fire, use sodium chloride (also known as salt). The special chemical fire extinguishers recommended for magnesium fires use a powder made of table salt to smother the fire, without causing another chemical combustion. These extinguishers are considered Class D fire extinguishers and are a good idea for owners of magnesium block engines.
Other flammable metals in auto manufacturing
Magnesium has a bad name because of its flammability, but it is not the only flame encouraging metal in the auto making world. Aluminum, also used extensively in car bodies, rusts easily over time. The rusted metal creates thermite, which burns just as hot as magnesium. The lithium batteries being developed for electric cars are also highly flammable. The lithium is actually combustible with contact with water, and can react to moisture in the air.
The myth of cars exploding because of their magnesium engines overheating or water getting under the hood are completely Importance Of Primary Sector false. They are myths based on the chemical properties of the metal magnesium that have been misunderstood.…

Where Is the Magnesium Alloy Car?
Barriers to construction of a car made of magnesium alloys:
Designing a lighter engine and car frame is the talk of the automobile industry. However, the car that is built of this stronger and lighter metal has yet to surface. Sure, magnesium has been used to create tire rims for decades. The magnesium block engine is also being manufactured. The problems with using the metal alloy to completely replace steel and/or aluminum have problems that will require industry-wide cooperation before such a car materializes.
3 Things Standing in the Way of the Magnesium Alloy Car:
Cost of Materials Electrician Certification Online
Magnesium is a metal that is easily mined, but costly to refine into form needed to manufacture an automobile. Magnesium must be extracted using very high heat, which is also necessary for the casting process. Parts that are Steps To Start A Small Business not cast can be cold formed, but excessive pressure is required. These processes use very high amounts of energy (to run the facility and equipment), making them cost prohibitive to factories and supply makers at-large.
New processes are being created to take away much of the costs. The Thixomolding process used to form magnesium alloy sheets is one such process. It is cheaper than traditional processes without sacrificing the integrity of the magnesium sheet being produced.
Materials Availability
The problem of having magnesium available for manufacturing is actually being debated in the 2011 session of Congress. With a sole company in the U.S. that produces magnesium from salt mines, and tariffs placed on all magnesium imports, the issue is quickly gathering steam. The costs and shipping time make magnesium unavailable for mass production outside of the few parts using the metal currently. If production companies return to the U.S. and/or the tariffs on imports are reduced, this may change.
Manufacturing Redesign
Auto parts and manufacturing machinery is designed for steel forming, casting, and sheeting. Magnesium has a different process that would require a refitting of the factory to accommodate. The costs of time lost, new machinery and facility modifications are prohibitive for the industry right now. There is also the gap in production caused by the change to magnesium alloy metal from steel, therefore, companies could lose a few anxious customers.
These barriers to the wider use of magnesium in automobile production are being studied now to find a solution. The auto industry is known to “gnaw” on an idea for a while before producing a solution, just look at the electric engine. The magnesium alloy car will not be forgotten in the meantime.…
