Magnesium Alloy Castings

Magnesium alloy castings can be produced by nearly all of the conventional casting methods, namely, sand, permanent, and semi permanent mold and shell, investment, and die-casting. The choice of a casting method for a particular part depends upon factors such as the configuration of the proposed design, the application, the properties required, the total number of castings required, and the properties of the alloy. Magnesium castings of all types have found use in many commercial applications, especially where their lightness and rigidity are a major advantage, such as for chain saw bodies, computer components, camera bodies, and certain portable tools and equipment. Magnesium alloy sand castings are used extensively in aerospace components.Get more news about magnesium alloy casting manufacturers,you can vist our website!

The method of codification used to designate magnesium alloy castings is taken from ASTM Standard Practice B 275 (Table 1). It gives an immediate, approximate idea of the chemical composition of an alloy, with letters representing the main constituents and figures representing the percentages of these constituents.
Generally speaking magnesium alloy designation consists of three parts:

Part 1: Indicates the two principal alloying elements and consists of two code letters representing the two main alloying elements arranged in order of decreasing percentage (or alphabetically if percentages elements and arranged in are equal). These letters are the following: A-Aluminum, E-Rare Earth, H-Thorium, K-Zirconium, M-Manganese, Q-Silver, S-Silicon, T-Tin and Z-Zinc.

Part 2: Indicates the amounts of the two principal elements and consists of two whole numbers corresponding to alphabet.

 

Part 3: Distinguishes alloys with the same percentages of the two principal alloying elements. It consists of the one of the following letters: A-First compositions, B-Second compositions, C-Third composition registered ASTM, D-High-purity and E-High corrosion resistance.
