Magnesium alloys are currently used in relatively small quantities for auto parts, generally limited to die castings, e.g., housings. For passenger cars, the general rule is that about 86% of their total life time energy use from the time of production to the time of disuse or scraping is consumed by carrying their own weight and persons around.
Magnesium alloys are mixtures of magnesium with other metals (called an alloy), often aluminum, zinc, manganese, silicon, copper, rare earths and zirconium. Magnesium is the lightest structural metal. Magnesium alloys have a hexagonal lattice structure, which affects the fundamental properties of these alloys.
AZ91 magnesium alloy sheets and pressed parts (new metal materials that can be used for various applications) The tensile strength is about 1.5 times higher than that of conventional materials. The elongation is about 3 times higher than that of conventional materials, leading to higher breakage , magnesium alloy parts
Lighter weight translates into greater fuel efficiency, making magnesium alloy parts very attractive to the auto industry. And these lighter parts come with good ductility and elongation properties, giving the materials good dent and impact resistance, as well as fatigue resistance.
Magnesium alloy forgings are also used in aerospace applications including critical gearbox parts for the Westland Sea King helicopter and aircraft wheels, both in ZW3. Forged magnesium parts are also used in aero engine applications.
Allite Super Magnesium, an alloy previously only available to military and aerospace but now being targeted at a range of other applications, is lighter and stiffer than aluminum, but not as , magnesium alloy partsLoz Blain
Magnesium and Aluminum Alloys: What We Should Know. Most of the aluminum is used for car parts such as cylinder heads, radiators, cars body and wheel rims. It was found, however, that the magnesium has several advantages over aluminum in terms of manufacturability due to its physical properties.
Magnesium Alloys. Alloy AZ91D is about 9 percent aluminum and 1 percent zinc, and it is the most widely used available magnesium alloy. AZ91D offers excellent strength, corrosion resistance and better castability compared to other magnesium alloys. By putting limits on impurities such as iron, copper and nickel,, magnesium alloy parts
Second, being the most reactive (or anodic) metal in the electrochemical series, magnesium is prone to severe galvanic attack when in contact with other metals. In automotive structural components such as engine cradles, road salts and debris can accumulate around the bolts and washers that mechanically affix magnesium parts to the car frame.
Figure 1 - Magnesium parts in U.S. Vehicles Source: USAMP Magnesium parts have been used almost everywhere in a vehicle, including the powertrain, body and closures, suspension and chassis, and interior. Many interior components such as steering wheel armatures and steering column brackets are made from magnesium where corrosion is not an issue.
Magnesium in car production - a weighting game. While magnesium may not be as popular for lightweighting as steel alternatives like composites, its application is gradually spreading from luxury marques to mass-produced models. Continuing just-auto/QUBE's series of research snapshots, this is the first of two parts reviewing lightweighting developments using magnesium and carbon fibre.Matthew Beecham
Magnesium alloys are well-known for being the lightest structural alloys. They are made of magnesium, the lightest structural metal, mixed with other metal elements to improve the physical properties. These elements include manganese, aluminium, zinc, silicon, copper, zirconium, and rare-earth metals.
Airframe General (Mod 4) 8347-8378. (1) In the corrosion process, it is the cathodic area or dissimilar cathodic material that corrodes. (2) In the Galvanic or Electro-Chemical Series for metals, the most anodic metals are those that will give up electrons most easily.
The use of magnesium alloys is now largely confined to non-gas turbine engine parts, and applications include gearboxes and gearbox housings of piston-engine aircraft and the main transmission housing of helicopters.
Magnesium, Aluminium along with its alloys offers a range of choices. This is due to the fact that they are lightweight and can operate under increasingly demanding conditions. Use of Magnesium in Aircraft Parts Casting In recent years, new Magnesium alloy castings has demonstrated superior corrosion performance.
Magnesium alloys have two major disadvantages for the use in automotive applications; they exhibit low high temperature strength and a relatively poor corrosion resistance. The major step for improving the corrosion resistance of magnesium alloys was the introduction of high purity alloys.
use magnesium alloys in the production of cars in such trans- mission parts and assemblies as the housing, the oil pan, the transfer box, the crankcase, the oil pump casing, the starter, the intake manifold, etc.
automotive parts is critical. Specific alloys are better for certain applications and often also need a coating to provide the longest life of the part. This paper details specific alloys used for certain aerospace and automotive applications. Additionally there is a review of coatings for magnesium alloys and an analysis of alloys and coatings.
Magnesium is a base material for numerous alloys. AZ91D is the most common magnesium alloy for die casting. It offers very good castability and toughness, and is an ideal material for light weight, highly durable parts. Hot-Chamber Die Casting. Chicago White Metal uses hot-chamber die casting to produce die cast magnesium parts. In this process, the metal injection components are submerged in a reservoir of molten magnesium.
Magnesium is the lightest of all structural metals, weighing 35 percent less than aluminum and 78 percent less than steel. Lightweight characteristics and wide availability make magnesium alloys suitable for mass production of components in cars and light trucks. However, the percentage of magnesium , magnesium alloy parts

Magnesium is the lightest of all light metal alloys and therefore is an excellent choice for engineering applications when weight is a critical design element. It is strong, has good heat dissipation, good damping and is readily available. Its properties make it easy to weld, forge, cast or machine.
Magnesium Alloy Die Casting Parts Posted at 03:57h in News by diecasting 0 Comments Nowadays magnesium die casting is becoming more and more popular, as magnesium die casting has excellent mechanical and physical property, and it provides much precision in dimension than aluminum and zinc die casting.
We need to reduce the mass of some small aluminum (6061) parts. We've already removed as much metal as possible, so the next step would be to machine them from a magnesium alloy. It seems as simple as just changing the material call-out on the prints, but nothing is simple. Our main vendor won't , magnesium alloy parts

Solid Magnesium requires significant heat to melt Melting point is the same as Aluminium Melting must occur before opportunity to burn Newer alloys (WE43, Elektron 21) are more flame resistant than older alloys Magnesium used in Aircraft Engines. More recently , resurgence of interest in Magnesium for interior applications
Magnesium is added to non-heat-treatable wrought alloys for its solid-solution strengthening effect. In general, solid-solution alloys are more resistant to corrosion than two-phase alloys. Magnesium makes aluminum more anodic and dilute aluminummagnesium alloys have a high resistance to corrosion, particularly in seawater and alkaline , magnesium alloy parts
