The heat treatable alloys acquire their optimum mechanical properties through a process of thermal treatment, the most common thermal treatments being Solution Heat Treatment and Artificial Aging. Solution Heat Treatment is the process of heating the alloy to an elevated temperature (around 990 Deg. F) in order to put the alloying elements or compounds into solution.
Magnesium alloys usually have desirable properties including high chemical stability, easy processing and manufacturing, and also lightweight. Magnesium alloys weigh about 70% of aluminum alloy weight and 30% of iron and steel weight. Most of these alloys

Chromium is a common addition to many alloys of the aluminum-magnesium, aluminum-magnesium-silicon, and aluminum-magnesium-zinc groups, in which it is added in amounts generally not exceeding 0.35%. In excess of these limits, it tends to form very coarse constituents with other impurities or additions such as manganese, iron, and titanium.
A study of weldability and fracture modes in electron beam weldments of AZ series magnesium alloys
The properties of all weldments were measured for at least three specimens, so that tensile tests can report the average ultimate tensile strain, and control parameters among the three AZ series magnesium alloys and their optimum and worst weldments
Corrosion and wear resistance improvement of magnesium alloys …
Moreover magnesium alloys show poor surface properties such as high chemical reactivity, low hardness, corrosion resistance and wear properties, which limit their extensive use in some appliions. Surface modifiion by laser technology seems a suitable solution to avoid these surface related drawbacks
NEW MAGNESIUM ALLOYS FOR TRANSMISSION PARTS
tional magnesium alloys, their insufficiently high creep resis-tance can lead to an abrupt decrease in the strength of all bolted joints, which causes weakening of the contact be-tween the casing and the bearing insert. This results in oil leakages and enhancement
Weight Loss with Magnesium Alloys | Science
In addition, the ease of recycling, compared with polymers, makes magnesium alloys environmentally attractive. Importantly, with a density of 1.74 g/cm 3 —about 30% less than aluminum, one-quarter that of steel, and nearly the same as many polymers—magnesium is attractive for lightweight structural systems and, most notably, automotive systems.

List of named alloys - Wikipedia
This is a list of named alloys grouped alphabetically by base metal.Within these headings, the alloys are also grouped alphabetically. Some of the main alloying elements are optionally listed after the alloy names. AA-8000: used for electrical building wire in the U.S. …
Magnesium alloys, especially precipitation hardened alloys, are used in casting. Sand, permanent mold and die casting methods are used, but plaster-of-Paris casting has not yet been perfected. Sand casting in green-sand molds requires a special technique, because the magnesium reacts with moisture in the sand, forming magnesium oxide and liberating hydrogen.
Alloys: Uses & Properties | Study
Aluminum Alloys Aluminum is a light weight metal and is a good conductor of heat and electricity, but is not a strong material. An aluminum alloy keeps the good properties but becomes stronger.
Different Types of Alloys & Use | Sciencing
An alloy is a metal created by coining two or more metallic elements. Different types of alloys are made for greater strength of the material or for resistance to corrosion. Alloys are created by melting the main metallic ingredient, and then the other ingredients are
