MA2-1 magnesium pipe, round ,rod

MA2-1 magnesium pipe, round ,rod


Wire and rod among varieties of magnesium metal most in demand in modern manufacturing. Magnesium is inexpensive and very light material (specific weight of 1.7 g/cm3). The cost of magnesium ingot is about 3 dollars per kilogram. Magnesium is resistant to gasoline, solutions of mineral oil, freon, kerosene. In alloy with other metals, magnesium has a very high specific strength and corrosion resistance. Magnesium has a boiling point equal to 1103 °C, its density is about 1.7 g/cm3 at 20 °C and the melting point of magnesium is 650 °C. the surface of the magnesium is covered with the oxide film, which collapses at a temperature of 623 °C, after which it burns. Magnesium powder and the foil is ignited with ordinary matches and burn in air and carbon dioxide.

Magnesium bar and wire is lightweight, and, consequently, high specific stiffness and specific strength in terms of weight. These types of hire is able to easily absorb the vibration. In addition, they are high-tech: easily pressed, rolled, cut, drilled, soldered and welded.


The disadvantages include the difficulties that arise in casting, melting and solidification of alloys. Given that magnesium is easily oxidized, the corrosion resistance of magnesium alloys is not very high.


Magnesium bar is produced by method of hot pressing according to GOST 18351−73. In hot pressing without additional heat treatment, the marking rod does not make additional designations. Example: MA2−1, MA1, MA15. When hardening of the rod, the marking will raise the index T4. For example, МА5Т4. For aged by artificial means bars use the index T1. For example: МА14Т1.


Rod produced according to GOST 18351−73, diameter 5 — 300 mm. With a diameter of 5 — 28 mm GOST permits the production of rod with a step of 1 mm diameter (5, 6, 7… 28 mm), with diameter 120 — 300 mm rods are made in increments of 10 mm (130, 140… 300 mm). Molybdenum rods of diameter 5 — 7 mm shall be manufactured only from grade MA5. Rods can be normal, high, and high accuracy. Measuring length, multiple length and random length (up to 6m).


As a rule, apply magnesium bars from magnesium alloys with other metals, usually with aluminum. They have high specific strength and lightness, used in helicopter, aircraft and airship: manufacturing of plugs and racks, chassis, housings, stabilizers, stiffeners, and various fragments.

A magnesium wire

Wire refers to a special type of rental, due to the fact that magnesium in its pure form is not strong enough for industrial applications, it is easy to air oxidation. Magnesium among structural materials is one of the lightest. Therefore, the desire to apply its benefits with the maximum benefit is understandable. In industry, typically use a magnesium wire, magnesium alloys and not of pure technical magnesium. For example, a very popular magnesium alloys with aluminum, featuring light weight and high specific strength. Wire of this type of alloy -a plastic, lightweight, has good electrical conductivity, it widely used in almost all industries — from transport engineering to electrical engineering.
