FAQ
- 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.
- What is the black powder on the surface of magnesium ingot AM50A?
- The first is the alloy composition is different: AM50, AM60 is Mg-Al-Mn series, AZ91D is Mg-Al-Zn series.
- 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
- 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
- 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.
- 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
- Will the enterprises that produce sponge titanium use magnesium ingots?
- Can be used, or can not be, according to process methods and the production of sponge too, one way is to use magnesium reduction method
- 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.
