The density, specific heat, melting point magnola.
Buy at affordable prices from the manufacturer of various grades of aluminum alloys with magnesium and manganese — magnolia — offers the company Elektrovek-steel. The supplier guarantees prompt delivery of the products to any point specified by the customer.
Features of structure and properties of magnons
A special feature of the chemical composition of the alloys under consideration is a noticeable magnesium content: from 0.4 to 6.3%, in addition, these alloys include manganese, iron, silicon and copper. In this case, the presence of 0.2… 0.8% manganese leads to an increase in the strength characteristics of Magnalium alloys. As a modifier, titanium is used, and the addition of chromium to some grades (for example, to AB) gives the alloy an increased resistance to corrosion phenomena.
There are casting and deformable magnolias. Casting magnolias are used as simple molded castings, sheets are produced from deformable rolling, and wire is drawn by drawing.
With a relatively high strength casting magnolias have low casting properties. The deformable aluminum-manganese-magnesium alloys are practically not hardened by heat treatment, but the alloys based on aluminum and magnesium are thermally non-hardy, highly plastic, and are characterized by high corrosion resistance. From the point of view of metallography, all magnanes are an α-solid solution with the inclusion of particles of the second phase — an intermetallic compound of magnesium and aluminum, with the presence of magnesium silicide.
The company Electrovek-Steel offers to purchase at a bargain price of the manufacturer of various brands of magnons. The supplier ensures the delivery of the products to any point specified by the customer.
Physical properties and application
The physical properties of the most common brands of magnums are given in the table:
|Brand alloy||Thermal conductivity, W / m 0 С, at a temperature of 20 0 С||Density, kg / m 3||Coefficient of linear expansion, x 10 6, 0 С -1||Specific heat capacity, kJ / kg 0 С, at a temperature of 100 0 С||Melting point, 0 С|
|AMg1||218… 226||2710||24||0.9218||643… 657|
|AMg2||155… 180||2680||24.2||0.9637||627… 652|
|AMg3||146… 148||2670||23.5||0,8799||593… 643|
Alloys containing a small percentage of magnesium, are used for the production of high decorative items and with increased reflectivity. AMG2… AMg4 alloys are used in lightly loaded welded structures, which must be operated in aggressive corrosive environments. AMg6 alloys are used in welded structures for the production of containers, ocean vessels, and also in cryogenic equipment.
The company Electrovek-Steel offers various brands of magnons at economically advantageous prices. The supplier ensures the timely delivery of products to any point marked by the consumer.
