When it comes to comparing magnesium and aluminum, their atomic structure plays an important role in understanding their various properties. Magnesium has two more protons than aluminum, making its atom larger with a higher mass. This is what contributes largely to its greater density compared to aluminum, which has fewer protons and a lighter atom.
Magnesium alloys have an α-phase single-phase structure at the eutectic temperature, and have an α+β (Mg2Al3) structure at room temperature. Magnesium has a certain solubility in the α phase, and the atomic radius of magnesium is very different from that of aluminum, so it can produce a strong solid solution strengthening effect. The α and …

There are four series of commonly used magnesium alloys ⑴Mg-Al-Si(AS) series: AS series has good creep resistance, high strength, good plasticity and toughness, but poor filling performance, and is often used to manufacture engine parts with high working temperature, such as engine crankshafts Wait. ⑵Mg-Al-Zn(AZ) series: AZ series has balanced mechanical properties and casting properties, …
1. Magnesium alloy processing and casting technology, mainly classified into gravity casting, pressure casting, low pressure casting, precision casting, lost foam casting, squeeze casting, etc. 2. Magnesium alloy extrusion forming process refers to pressing magnesium alloy into profiles with various cross-sectional shapes, such as rods and pipes, through isothermal extrusion or hot extrusion on a …
Magnesium is a silver-white active metal that can conduct electricity and is soft. It has relatively strong reducing properties. Magnesium oxide can be generated by burning magnesium strips. Magnesium is often used as a reducing agent to replace metals such as titanium, zirconium, uranium, and beryllium. It is mainly used in the manufacture of light …
Magnesium alloys are alloys based on magnesium and added with other elements, such as aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium. Magnesium alloy has the advantages of low density, high strength, large elastic modulus, good heat dissipation, good shock absorption, etc., and has a greater ability to withstand impact …
For manufacturers that can industrially produce magnesium content higher than 99.99%, we collectively refer to magnesium ingots that meet the national standard of 99.95% to 99.99% as “high-purity magnesium”, without deliberately distinguishing between “high-purity magnesium” and “ultra-purity magnesium”. In addition, the titles of magnesium ingots are also very complicated, such as “magnesium ingots”, “first-class magnesium …

A complete machining procedure should include the following: 1. Cutting tools should be kept sharp and have a larger relief angle and clearance angle; do not use blunt, chipped or cracked tools. 2. Under normal circumstances, try to use a large feed rate for processing, and avoid using a small feed rate to generate larger …
Due to the low mechanical strength of pure magnesium, aluminum-magnesium alloy is mainly used. It is light and has a certain strength. It is an important structural material, used for aircraft fuselage, wings, engine parts, wheel frames, automobiles, and trains. Magnesium is used as a nodularizing agent for ductile iron, a desulfurizing agent for steelmaking, …
Fire extinguishing usually adopts the following materials or methods: 1. Class D fire extinguishers: the material usually uses sodium chloride-based powder or a passivated graphite-based powder. The principle is to suffocate the fire by excluding oxygen; Fire extinguishers are only produced by foreign manufacturers. Therefore, when purchasing, you must look for products with quality certification …
