Aerospace Magnesium

Aerospace Magnesium

The element magnesium occurs abundantly in combination with other materials in the Earth’s crust. Symbolized by the letters “Mg” on the Periodic Table, this alkaline earth metal derives its name from the element Magnesia. It possesses a light weight, having a density of just 1.738 grams per cubic centimeter.

Although magnesium occurs widely, for centuries it obtained comparatively limited use in metal working, possibly due to the difficulty of extracting magnesium in a purified form and handling it safely in metal production environments. Magnesium possesses combustible properties. It produces a brilliant white light during combustion, a property which has made it an important component of pyrotechnic products, some optical equipment, and flares.

Magnesium Alloys

今天,大多数的汇率政策urers seeking to harness the properties of magnesium utilize magnesium alloys. To create an alloy, a manufacturer combines two or more metals or a metal with another element or elements in a molten form. When the molten material solidifies, it will display new properties determined by its constituents.

例如,镁合金通常有助于生产轻质产品。改变这些合金中的元素的组合允许金属蛋白患者在镁中形成显示一些所需特性的金属部件。例如,镁合金可以为铝合金提供更轻的重量替代,以产生一些组分。

合金中不同成分的百分比冲击密度,拉伸强度,耐磨性,耐腐蚀性等重要工程考虑因素。一些流行的镁合金将镁与铝,铜,锌,锰或硅结合在一起。由镁合金形成的金属部件通常比钢或铁合金生产的可比部件小。

Magnesium IN Aerospace INDUSTRY

Aerospace magnesium has enjoyed widespread demand since the latter half of the Twentieth Century. The growth of the aviation industry ultimately created a need for lightweight structural metals. This concern assumed greater importance as scientists designed aerospace equipment. By reducing the weight of airplanes, rockets and satellites, manufacturers may decrease fuel costs. They need less fuel to power lighter-weight craft across the same terrestrial distances.

飞机设计师迅速发现,通过用铝制件替换一些钢结构可以显着降低飞机重量。尽管由于其可燃性,最初的镁作为材料被证明是非常难以制造的制造环境中的,但在二十世纪在二十世纪的众多有用的镁合金的发展使得在某些部件中使用镁。

Aerospace Applications For Magnesium Alloys

在近几十年来,工程师已经为不同的镁合金发现了各种有用的应用。这些创新经常涉及用较轻的重量零件取代较重的金属部件。潜在的,这些设计修改有助于略低燃料成本。或者,它们提供飞机和太空胶囊设计团队,有机会包括其他乘客设施(或货物)而不超过适用的重量限制。

For example, the British firm Magnesium Elektron created a proprietary magnesium alloy called “Elektron® 43 alloy” which the firm offers for use in aircraft interiors. By replacing structural components inside passenger seating with comparable parts formed from new magnesium alloys, a reduction may occur in the overall weight of seating. Other cockpit applications for magnesium alloy components include the use of instrument display panels containing magnesium alloy parts.

The Boeing Company, a large aircraft manufacturer, reportedly employed magnesium alloy parts in jet engine fan frames and engine thrust reversers in several models of large commercial passenger jetliners. Many skilled aircraft and aerospace engineers seek to develop new uses for magnesium alloys. Bunty LLC assists companies and entrepreneurs seeking to obtain experienced aerospace magnesium alloy consultation, engineering and parts manufacturing services for commercial purposes.

Aerospace engineers reportedly include magnesium alloy components in some spacecraft, missiles, and satellites. These parts contribute to optical imaging technologies widely used in aerospace and non-aerospace applications, and possibly to some structural components. Specific information about most aerospace applications likely remains proprietary in nature and unavailable to the public.

在航空航天部门使用镁合金的优点

Why would the aerospace sector discover advantages in employing magnesium alloys in aerospace technology?

  1. By selectively using light magnesium alloys in lieu of heavier construction materials, design teams may reduce the overall weight of rockets, missiles, satellites or other aerospace vehicles. Just as decreasing the weight of a plane offers commercial benefits in aviation, supplying a lighter weight payload imposes less of a takeoff burden upon a rocket.
  2. 随着全球产量的增加,虽然比铝更昂贵,但镁价格可能会在未来显着下降。今天公司已经发现了许多镁来源。在某些情况下,较低的成本镁可能有助于生产更实惠的镁合金。镁合金的可用性和多样性的增加会增加熟练的航空航天工程师的设计选择。
  3. 据报道,一些镁合金提供重量轻,延展性。在航空航天工程师渴望这种特性的情况下,能够耐动地耐动地,由镁合金形成的部件可以在其设计中进行重要作用。特定合金和预期的环境挑战将决定是否使用镁合金部分。
  4. 在一些航空航天环境的可燃性magnesium may prove desirable. This feature has contributed to magnesium’s important role in flares, for instance. If design teams desire a satellite to burn vividly upon re-entry into the earth’s atmosphere, then using magnesium or specific magnesium alloys for some components might offer some design advantages.
  5. Metallurgists have reportedly developed capabilities to perform finishing for some highly refined magnesium alloys to improve their corrosion resistance capabilities. Highly corrosion resistant magnesium alloys can perform useful roles under some conditions. Combined with the light weight of magnesium, this property may appeal to aerospace designers.
