Q:What is magnesium aluminum alloy and what is its use?
Magnesium alloy is magnesium ingots and aluminum ingots in protective gas melted into. For a long time about the structure of Al Mg alloy with two kinds of argument. One theory is that magnesium alloy is a simple physical mixture; another is magnesium alloy changes inside the crystal structure, is not a simple physical mixture.
Q: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.
Q:Causes of high manganese content in magnesium ingot
Magnesium in the air in the combustion reaction of oxygen, magnesium and Magnesium Oxide in the air, and the quality of the quality of the resulting Magnesium Oxide equal in response to magnesium and oxygen quality, so the quality of the product than the quality of the original magnesium increases.
Q:The industrial application of magnesium and the main title and technical difficulty of producing magnesium products with magnesium chloride as raw material
1, unit investment is low.2, the production cost is low. As a result of magnesium ore, coal and other phasesThe prices of the raw materials are lower, the labor and management costs are not high, so the totalLower production costs.3, magnesium and related resources are rich. China is the richest country in magnesium resourcesOne of。 The total reserves of magnesite are 2 billion 700 million T, dolomite mine about 4000000000 T, and QinghaiThe potassium and magnesium salt and coastal brine magnesium reserves are very large.
Q:What are the generally feasible surface treatment methods for magnesium alloy die castings?
1. chromate passivation method, which is the most widely used and the most important method in industry. The so-called chromate passivation solution is metal with chromic acid, chromate or dichromate as a major component of the film on the metal surface to form a compound composed of trivalent chromium and hexavalent chromium and six metal itself, this film has protective passivation metal corrosion inhibition for. The specific passivation process is to dip the magnesium ingot which is intended to be passivated into the passivation solution. At this time, the surface metal is oxidized by the solution, forming metal ions into the solution. Since the solution is acidic, the following reactions occur: 3Mg ten, 2HN03 = 4Mg0, ten H20, ten 2N02. anodic oxidation is a surface treatment method to increase the thickness of base metal oxide film by electrolytic reaction and to improve the film properties. The film has excellent corrosion resistance and abrasion resistance.
Q: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
Q: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
Q:What are the differences between aluminium magnesium alloy, aluminum alloy and plastic steel?
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.Have a great impact on the quality of production safety and product content of magnesium, aluminum magnesium alloy standard in all about how many of the fireworks aluminum content of 50%. activity. But now the production of magnesium alloy for many enterprises and private enterprises, in recent years the aluminum ingot is more expensive than the magnesium spindle, driven by interests, are not in accordance with GB production. Now in the magnalium powder the aluminum content is generally less than 50%, some low aluminum content to increase the properties of 40%. magnesium alloy content makes the properties close to magnesium, so the pyrotechnic impact sensitivity and friction sensitivity increase, pyrotechnics is more sensitive, thereby increasing the risk. We may use the following chemical mechanism to test the content of magnesium alloy in aluminum.
Q:What are the surface defects of magnesium alloy rolling?
When the deformation rate is too large, it is easy to cause serious cracking.
Q:Why the cost of ferrosilicon production will lead to a rebound in the price of magnesium ingot?
The rising price of ferrosilicon means that the cost of raw material will rise and magnesium ingot producers will inevitably raise their prices.
