Brass was known in ancient Rome, but has been actively used since the beginning of the nineteenth century. Brass-based alloy of 2 metals: Zn + Cu. Copper in the structure much more. If the copper content reaches 90% — the alloy called red brass has good ductility and corrosion resistance, and has a Golden-reddish hue and is widely used not only for industry but also for manufacturing various decorative elements. The price depends on the metal content in the alloy. The cheapest alloy with highest content of zinc as Zn metal is relatively cheap. But if the brass contains more than 45% of the total, physical and technical properties of the metal deteriorates, this alloy is rarely used by the industry. It becomes less ductile and more brittle. But if the zinc content is less than 30%, it hardens the composition without loss of plasticity.
Types of brass
Dependent on the chemical composition there are several types of brass. Simple single-phase brass has a high plasticity, contains not less than 30% Zn. It has good resistance to atmospheric moisture, resistant to temperature extremes. A simple two-phase brass is well forged and rolled, and has good ductility. Another type — multi-phase brass, combining the advantages of the first two types. If in an alloy of copper and zinc, to reserve a component, such as lead you get special brass, which is marked with two letters. After the letter L is written with the first letter of the metal, which is optionally included in the composition. Then specify the percentage of copper. If the composition contains more elements, then their content is written with the numbers separated by a dash.
Brass car with exceptional adaptability. Produces machine parts and mechanisms of complex shapes, ranging from watch gears and ending with bearings, pipes, tubes, parts, chemical, sanitary equipment. Brass car has good anti-corrosion properties, so popular in the manufacture of taps, valves. Due to the plasticity, brass can be easily get the various types of rolled products: sheet, rods, wire. Of the thin bars make the electrodes for special types of welding. Plates, tapes, sheets, various profiles are widely used in mechanical engineering. Under the order is possible to buy hire custom settings.
Drawback — corrosion cracking. If the part shape by cold pressure inside accumulate residual stresses. The cracks can penetrate aggressive substances, moisture, which leads to the destruction of the material. To avoid this, brass is slowly heated to t° 260 °C, and slowly cooled. This low temperature annealing. Those items, which are made by casting, are deprived of this lack, they don’t need annealing.
Application. Wrought brass
Wrought brass, contain a large percentage of copper, up to 90%. The alloy has good anti-corrosion, anti-friction properties, plasticity. Used in the manufacture of various accessories interior decoration. easily welded with other metals, for example, with steel. the result is a material that is called a bimetal, it is widely used in electrical engineering.
It is used in the manufacture of tubes of small diameter for the needs of the automotive industry, refrigeration equipment. From it produce radiators, pipes, bushings. Widely used due to its anti-corrosion properties for plumbing products: faucets, valves, and also some kinds of bolts, rivets.
Widely used in shipbuilding, in the manufacture of the housing, bolts, door handles, fittings. Resists the action of sea water. Used in aircraft construction and chemical equipment.
Of these, parts of sensors, gauges and also the gears, bearings for the needs of heavy machinery that operate under heavy load at t° to 300 °C,.
Jewelry brass — jewelry making at home, interior, manufacture of Church utensils. From a distance it can be mistaken for gold because of the characteristic Golden hue. There are alloys bright yellow and copper colors.
