Copper grades are widely represented in various industries: this non-ferrous metal, due to its unique characteristics, is one of the most common. All grades of this metal are distinguished by high ductility and corrosion resistance when used in various environments, with the exception of ammonia and sulfur dioxide.

Modern industry produces copper blanks in the form of sheet material, pipes, wire, bars and tires. There are oxygen-free (M0) and deoxidized (M1) copper, products from which are widely used in the electrical, electronic and vacuum industries. In oxygen-free grades, O2 is contained within 0.001%, in deoxidized grades - 0.01%.

There are a lot of grades that are classified according to the purity of the base metal content today: M00, M0, M1, M2 and M3. The M1r, M2r and M3r brands are also common, which are characterized by an oxygen content in the range of 0.01% and phosphorus 0.04%. For example, grades M1, M2 and M3 contain oxygen in the range of 0.05–0.08%.

Copper grade	M00	М0	M0b	M1	M1r	M2	M2r	M3	M3r	M4
Copper content, %	99,99	99,95	99,97	99,90	99,90	99,70	99,70	99,50	99,50	99,00

Impurities in copper alloys

Solid solutions forming with copper

Such impurities include aluminum, antimony, nickel, iron, tin, zinc, etc. These additives significantly reduce electrical and thermal conductivity. The grades that are mainly used for the production of conductive elements include M0 and M1. If antimony is contained in the composition of the copper alloy, then its hot working by pressure is much more difficult.

Impurities that do not dissolve in copper

These include lead, bismuth, etc. Not affecting the electrical conductivity of the base metal, such impurities make it difficult to process it with pressure.

Impurities that form brittle chemical compounds with copper

This group includes sulfur and oxygen, which reduces the electrical conductivity and strength of the base metal. The sulfur content of the copper alloy greatly facilitates its machinability by cutting.

Standards for Copper Alloys

State standards stipulate the rules for marking copper and its alloys, the designation of which corresponds to a certain structure.

The fact that we have one of the grades of copper in front of us is evidenced by the letter "M" in its designation. After the initial letter in the marking of copper and its alloys, numbers (from 0 to 3) follow, conditionally indicating the mass fraction of the base metal in their composition (for example, M3 copper). After the numbers, capital letters follow, by which it is possible to determine how this brand of copper was obtained. Of the technological methods, the following are distinguished:

• cathodic (k);
• a deoxidation method involving a low content of residual phosphorus (p);
• a deoxidation method involving a high content of residual phosphorus (p);
• without the use of deoxidizers - anoxic (b).

Examples of markings of such brands and may look like this: M2r, M1b.

A number of copper grades with unique characteristics are actively used in various industries.

• M0 - this brand is used for the production of conductive elements and for adding to alloys that are of high purity.
• M1 - this brand is also used to produce conductive elements, rolled products of various profiles, bronze, parts for cryogenic equipment, electrodes for, wire and rods (used to perform in an inert gas environment), Consumables for making parts made of copper that do not experience significant loads during operation.
• M2 - this brand allows you to get products that are well processed by pressure. Copper M2 is also used for parts of cryogenic equipment.
• MZ - parts from this grade of metal are produced by the rolling method.

GOST 859-2001, which stipulated the requirements and characteristics of copper alloys, was replaced in 2014 by a new state standard (859-2014), which was recorded by the relevant Order of the Federal Agency for Technical Regulation and Metrology. new standard in its main points it is almost identical to GOST 859-2001.

GOST 859-2001 on copper grades

This state standard document applies to cast and deformed copper semi-finished products, as well as to copper made in the form of cathodes.

What associations does the word metal evoke in you? People with a narrow worldview will say that there is nothing special about this word, but for the majority it is associated primarily with reliability and, for some reason, with a hard blow) Now it’s even hard to imagine how humanity used to get by on such a hardy and almost indestructible substance . But since now all industries are closely connected with metal, namely products made from it, we need a company that will sell rolled metal at affordable prices. One of such useful and responsible companies is Metal rolling in St. Petersburg.

Made from copper grades M1, M1R, M2, M2R, M3, M3R according to GOST 495-92, chemical composition which corresponds to GOST 859.

Among the huge range of product varieties, you can choose the most suitable one for yourself (copper sheet, reinforcing strands, corners, etc.) for you and buy to be sure of its strength, because it is strength that determines 100% of the quality of any metal.

Specifications of Copper Sheet

Each metal alloy has its own individual characteristics that determine their application and service life. Having decided on the appointment, you feel free to choose the right one for yourself, taking into account all the features. For example, a copper sheet is very convenient to use, but titanium sheets are distinguished by good strength and require a good ability to use it.

copper sheet weight

Almost every product that leaves the factory has a standard weight for easy transportation and packaging. Just imagine what would happen if each metal was produced in an arbitrary size. It would make your life very difficult.

Properties of copper sheets.

The physical and mechanical properties of the copper sheet depend on the grade of copper, oxygen content, alloying additives and impurities, but the main characteristics can be noted:

• corrosion resistance

• presentable appearance
• tolerance of sudden changes in critical temperatures without deformation

Copper sheets are 99% base material to match the chemical and physical characteristics of the sheet blank, subjected to fire refining, which removes excess constituents and oxygen.

Application of copper sheet.

Due to its unique properties, copper sheet is actively used:

• in electrical engineering
• mechanical engineering
• instrument making
• shipbuilding
• aircraft industry
• construction
• finishing
• Food Industry
• medicine

Good machinability makes it possible to create complex structural solutions from a copper sheet, to produce parts for electrical appliances and radio equipment by stamping. Copper sheets have proven themselves as roofing material, roofs made of copper sheets do not require additional coating, anti-corrosion properties increase the service life of such a roof up to 100 years.

In interior and exterior decoration, copper sheets are used to create both flat and voluminous, curvilinear interior solutions. After polishing, the copper sheet will shine with gold and will please the eye for many decades.
