Lviv copper circle M1, M2, blank, copper rod, copper ingot, rolled and casting, copper plate

A copper circle is a semi-finished product that belongs to a variety of copper bars. Its main properties are good corrosion resistance, high electrical conductivity, long wear resistance and ease of machining. Due to these qualities, the product is in demand in various types of industry: energy, electrical engineering, mechanical engineering and instrument making.
Since the copper circle, or copper rod, has valuable physical and chemical qualities (its melting point is 1083 ° C at a density of 8.98 g / cm2), it can be used literally in any area.
According to the main parameters, copper circles are:

     Hot-formed and cold-formed (according to the production method);
     Normal, increased and high precision production;
     Soft, semi-hard and hard (according to the state of the material);
     Unmeasured, multiple measured length or length in bays.

Scope of copper circles
Copper circle is a suitable material for the manufacture of shafts, nuts, washers, valves, gears, various units and assemblies. Copper rod is excellent for stamping, pressing, drilling, milling and cutting.
Copper circles are widely used in the field of heating, air conditioning, water supply, roofing. Their high resistance to corrosion, reliability and quality contribute to the fact that the sale of copper circle is a very popular service. Despite this, the price of a copper circle remains at an acceptable level.
  The cost of rolled copper is quite high. But it pays off with the durability of products and their unique properties:

     Corrosion resistance - allows you to use the round timber for a long time without losing its functionality, aesthetic appearance. copper circle
     Excellent electrical and thermal conductivity - these qualities are in demand in the electric power industry, the manufacture of air conditioners, high-performance devices and devices.
     The bars are plastic, easy to process - they are easy to press, drill, stamp, solder and weld.
     Rolled stock tolerates temperature fluctuations well.
     The material is environmentally friendly, characterized by antibacterial properties.
     The rods are light weight.

Products are distinguished by reliability, wear resistance, possibility and ease of machining, versatility of application. Depending on the brand of copper or its alloy, products receive certain characteristics. In terms of hardness and strength, copper bars are inferior to steel bars, but surpass them in terms of ductility.
GOSTs for manufacturing
Round bars are classified according to the method of manufacture, the accuracy of execution, and the length of the bar. Copper bars with a round cross section are produced in accordance with GOST 1535-2016. Depending on the method of application and the brand of raw materials, they are produced:

     drawn;
     extruded;
     Pressed.

Extruded rolled products are obtained by pressing technology with continuous rotation. Drawn (hot-formed) and extruded (cold-formed) rods are produced by pressure forming. The accuracy of execution is normalized as normal, increased, high.
The standard establishes the following product diameter (in mm):

     Drawn - from 3 to 50;
     Pressed - from 20 to 180;
     Extruded - from 15 to 50.

The length of the bars are made measured, unmeasured length:

     From 2.0 m to 5.0 m (with a diameter up to 40.0 mm);
     From 1.0 m to 4.0 m (with a diameter of 40.0-80.0 mm);
     From 1.0 m to 3.0 m (with a diameter of 80.0-100.0 mm);
     From 0.5 m to 2.0 m (with a diameter of more than 100.0 mm).

The size of the maximum deviations in terms of the diameter of the section, the bevel of the cut, ovality, and curvature is also normalized. According to the state of the material, the products can be soft, semi-solid or solid. Rods are also produced with increased plasticity. Primary copper grades M1, M2 or technical grade M3 are used for production.
Products must have a flat, uncontaminated surface without delaminations, cracks. It is allowed to have small-sized captives, shells, dents, scuff marks, and traces of editing.
According to GOST 10988-2016, round steel is produced from oxygen-free copper grade M0. It is intended for use in the electrovacuum industry. Rods are made:

     Drawn - diameter 5.0-50.0 mm;
     Pressed - diameter 14.0-175.0 mm;
     Extruded - diameter 15.0-50.0 mm.

By length, they produce dimensional, non-dimensional, multiple dimensional rolled products:

     From 0.5 m to 5 m (d to 40.0 mm);
     From 0.5 m to 4 m (d 40.0-80.0 mm);
     From 0.5 m to 3 m (d 80.0-100.0 mm);
     From 0.5 m to 2 m (d over 100.0 mm).

The density of the metal is 8.98 g/cm3, the melting point is 183 °C. As a result, the copper circle is a very popular semi-finished product (nuts, washers, bushings, shafts) in the manufacture of a wide variety of components and assemblies.
Scope of application
Copper circles are used everywhere:

     Air conditioning, cooling systems, heat exchangers;
     Electrical installations;
     machine buildinglinen industry;
     Instrumentation;
     Water and gas supply;
     Aviation, shipbuilding, space industry.

Copper bars are in great demand for the manufacture of hardware - nuts, washers, bushings, bolts, nails. High-quality gears, furniture fittings, shafts, valves are produced from them. Rolled metal of this type is often used in roofing. Gutter elements are made from it. Also, the copper circle is used in the production of valves, automotive, connecting parts, devices.
Beautiful appearance is suitable for creating architectural elements, decor items. Designers often use rental in the design of interiors and exteriors of buildings. Products are in demand in the food and chemical industries, as they are able to withstand the action of aggressive environments well. Copper round timber is also used for the production of fittings and cable products.

Scope of copper circles
Such copper circles are especially popular in instrument making and mechanical engineering. Also, these products can be popular in industries that are related to the construction of ships, the construction of automobiles, the aviation industry, as well as the industry related to the manufacture of watches.
Such a copper circle can be used as a blank for the production of certain parts and spare parts. These include: bolts, gears, screws, as well as for the production of systems for regulating the supply of gas, water.
Copper circle products are in demand because they are very resistant to rust formation. Due to this property, it can be used where contact with a corrosive environment is possible. It is because of these properties that this material is widely used in shipbuilding.
It can be said that the scope of this material is not limited in any way. But it is worth noting that the copper circle is not designed for heavy loads.
Nowadays, there is a large selection of different copper circles of various diameters, lengths, and alloy compositions, which will help you choose the perfect copper circle specifically for your purposes.
Such a copper circle can be supplied both in bundles and in bays. Each package will be marked with alloy grade, length, diameter and other data.
