Rolled brass

Technical Characteristics

Brass has been known since ancient Rome, but began to be actively used since the beginning of the nineteenth century. Brass is based on an alloy of 2 metals: Zn + Cu. Copper is much more in composition. If the copper content reaches 90% - an alloy called tompak - has good plasticity and corrosion resistance, has a goldish-reddish color and is widely used not only industry, but also for the manufacture of various decorative elements. The price depends on the metal content of the alloy. The cheapest alloy is the one with the highest zinc content, as Zn is a relatively inexpensive metal. If Zn content in brass exceeds 45% of total volume, the physical and technical properties of the metal are worsening, and such alloy is seldom used by industry. It becomes less ductile and more brittle. But if the zinc content is less than 30%, it strengthens the composition without loss of ductility.

Brass Types

Depending on the chemical composition, there are several types of brass. Single-phase plain brass has high ductility, contains at least 30% Zn. It has a good resistance to atmospheric moisture, well resists temperature changes. Two-phase brass is well forged and rolled, has good formability. Another type is multiphase brass, which combines the advantages of the first two types. If an alloy of copper and zinc is joined by some additional component, for example lead, then a special brass is made which is marked with two letters. After the letter L is written first letter of the metal that goes further in the composition. After that, the percentage of copper content is indicated. If there are several additional elements in the composition, their content is written in numbers with a dash.

Advantages of

Brass rolled products are characterized by exceptional manufacturability. Machine parts and mechanisms of complex shapes are made of it, from clock gears to bearings, sockets, pipes, parts of chemical and sanitary equipment. Brass rolled brass has good corrosion-resistant properties, so it is in demand for the manufacture of faucets and stop valves. Brass can be easily made into different rolled products: sheets, rods and wires. Thin rods are used to make electrodes for special welding applications. Plates, bands, sheets and a variety of profiles are widely used in mechanical engineering. It is possible to buy rolled steel of non-standard parameters to order.

Disadvantages

A significant disadvantage is corrosion cracking. If the part is formed by cold pressure, residual stresses accumulate inside. In the microcracks can penetrate aggressive substances, moisture, which leads to the destruction of the material. To avoid this, the brass is heated slowly to 260 °C, and cooled just as slowly. This is a low-temperature annealing process. Those parts that are made by casting do not have this disadvantage, they do not need annealing.

Application. Wrought Brasses

Wrought brass contains a large percentage of copper, up to 90%. The alloy has good anti-corrosion and anti-friction properties and ductility. It is used in the manufacture of various fittings interior decorations. easily welded with other metals, for example, with steel.We get a material called bimetal, it is widely used in electrical engineering.

Double Brass

It is used in the manufacture of small-diameter tubes for the needs of the automotive industry, refrigeration technology. It is used to make radiators, spigots and bushings. Brass is widely used for sanitary applications thanks to its anti-corrosive properties: faucets, valves and some types of bolts and rivets.

Special Brass

Widely used in shipbuilding in the manufacture of instrument casings, bolts, door handles, fittings. Resists the action of sea water well. Used in aircraft construction and for chemical equipment.

Multicomponent brasses

They are used for producing parts of sensors, gauges, as well as gears, bearings for the needs of heavy machinery, which works under heavy loads at t ° up to 300 ° C.

Jewelry Brasses

Jewelry Brass - the manufacture of jewelry in the home, the interior, the manufacture of church utensils. From a distance such a product can be mistaken for gold because of the characteristic golden hue. Brass is also available in bright yellow or copper colors.
