FAQ

What is the black powder on the surface of magnesium ingot AM50A?
AZ91D, the most widely used magnesium alloy, has high strength and excellent casting performance. It is used in motorcycles, computer parts, housings, and lids
What harm does magnesium alloy have to human body?
The main element of magnesium aluminum alloy and AZ91D is magnesium. As long as it is not dust (flammable or explosive), direct contact with magnesium ingot is harmless
Why the cost of ferrosilicon production will lead to a rebound in the price of magnesium ingot?
75# ferrosilicon in pidgeonmagnesiumprocess often used in high temperature smelting process of magnesium metal, will be replaced from CaO.MgO mg, each ton of magnesium will consume 1.2 tons of ferrosilicon, plays a big role in magnesium production.
Causes of high manganese content in magnesium ingot
Potassium Permanganate heat decomposition of potassium manganate, manganese dioxide and oxygen, and the quality of solid oxygen generating surplus.
What are the generally feasible surface treatment methods for magnesium alloy die castings?
Your question is difficult to answer, the general casting magnesium alloy surface treatment should be divided into surface coating treatment and surface treatment, although the two are related, but in the process and technology, but there is a big difference, its main features are not the same. Therefore, you must specify the purpose and function of your work before you can tell you the actual surface treatment.
What are the surface defects of magnesium alloy rolling?
Because magnesium alloys are made of magnesium ingots, while magnesium ingots contain other elementsTherefore, magnesium alloys are generally used in die castingAluminum alloy is rolled only
What is magnesium aluminum alloy and what is its use?
Magnesium ingot and aluminium in the above 1150K, reaction of aluminum and oxygen in the air to form a-Al2O3, the crystal chemical properties of alumina is inert, a barrier and isolation. Less than 1150K, in the B-Al2O3 and the crystal reaction with acid magnesium alloy not inner protection.
Will the enterprises that produce sponge titanium use magnesium ingots?
In the process of reduction, trace impurities in TiCl4 such as AlCl3, FeCl3, SiCl4 and VOCl3 are reduced by magnesium to form corresponding metals. These metals are all mixed with sponge titanium. Impurities such as potassium, calcium and sodium, which are mixed with magnesium, are also reducing agents. They reduce TiCl4 and produce the corresponding impurity chlorides respectively. Magnesium reduction process includes: TiCl4 liquid, gas and liquid gasification TiCl4 Mg diffusion of TiCl4 and Mg molecules adsorbed on the active center, in the active center of chemical reaction, nucleation, crystal growth, titanium MgCl2 desorption, diffusion MgCl2. The key step in this process is crystallization nucleation, accompanied by heterogeneous nucleation with chemical reactions.
