Copper alloy M1 has excellent physical characteristics: high electrical conductivity and low (0.018 μΩ) electrical resistivity, which after heat treatment by annealing decreases by another 2.8%. The plastic properties of the alloy make it possible to use it for the manufacture of parts used in fixed joints with operating temperatures up to 250°C

Due to the very low impurity content, the cost of M1 copper is 20% higher than the other popular brand, M2. Various types of rolled copper made from M1 alloy are widely used in cryogenic industries. Due to its thermal stability, its viscosity, strength and plastic properties do not change under extreme temperatures.

Pure copper

Grade M0 contains 99.95% Cu and no more than 0.05% impurities. According to special technical conditions, several grades of vacuum copper and especially oxygen-free pure copper are produced, which is used in the electric vacuum industry. Strips, tapes, rods, and pipes are produced from oxygen-free copper of series A and B. Tapes and rods are made from vacuum pure copper. Rods are produced from pure copper, which is deoxidized with manganese. All these semi-finished products are used in the electrovacuum industry. Oxygen-free pure copper is characterized by a low (-100°C) recrystallization temperature.

Application of M1 copper

M1 copper is widely used for:

• production of current conductors, tin-free bronze rolled products;
• production of rods and wire for welding;
• creation of cryogenic equipment designs;
• production of electrodes suitable for welding copper and cast iron products.

Also, many products are made from M1 copper alloy. The production of each of them has its own characteristics. Copper sheets and tapes are checked for bending. The slabs are also subjected to certain tests. Pipes with a large cross-section are made by pressing. The properties of finished products are checked for compliance with GOST.

Copper grades for electrical engineering and in general

Copper grades consist of the letter “M”, which means copper. This is followed by a number from 0 to 4. Sometimes one of the letters is then found that characterize the method of producing the metal: k - cathode, p - deoxidized with low residual phosphorus, f - deoxidized with high residual phosphorus, b - oxygen-free. Oxygen-free is M0, and deoxidized is M1. There are many grades of copper, let's look at some:

A special grade of copper is M1E. This is electrical copper, which is produced in the form of tires, rods of various diameters and sections. It can be extra hard, hard, semi-hard and soft. The conductivity of soft copper is a couple of percent higher.

Available in the form of tires, rods, circles. The rods, in turn, have a diameter from 5 to 40 mm and a cross-sectional shape - circle, square, hexagon. This type of copper has a limited shelf life - up to a year for soft copper and six months for hard copper.

Copper m1 m2 m3 difference

Due to their properties, various grades of copper are very popular in the industrial environment. This metal is good because it is flexible and, regardless of the operating environment, with the exception of exposure to sulfur dioxide and ammonia, it is resistant to corrosion.

The external distinctive feature of copper is its pink-red color. Depending on the purity, copper is divided into types with the technical designations M1, M2, M3. This metal comes into production in the form of wire, sheets, pipes, and rods.

This is due to different application situations.

Based on its composition, copper is divided into oxygen-free and deoxidized; the symbol is M0 and M1, respectively. Oxygen-free is used in the manufacture of parts for electrical, electronic, and electrovacuum industrial products. O2 in oxygen-free brands is no more than 0.001%, and in deoxidized ones - 0.01%.

The breakdown of copper grades is presented in the table:

Features of production and application

Copper of a chemical composition similar to the domestic M1 grade is produced in many countries with a developed metallurgical industry:

• Japan (JIS standard), USA – C1100, C1220.
• European Union (EN standard) – Cu-ETP.
• England (BS standard) – C106.
• France (AFNOR standard) – Cu-B.
• Italy (UNI standard) – Cu-DHP.

The undoubted leader in the production of various oxygen-free copper alloys - analogues of the domestic M1 grade is the German metallurgical industry. In accordance with DIN and WNR standards, non-ferrous metallurgy plants produce three types of alloys - Ecu57, ECu58, SF-Cu.

The coefficient of friction of metal with lubricant is 0.011, without lubricant - 0.043. There are two categories of alloys according to GOST 1173-2006 in terms of Brinell hardness:

During the casting process, it must be remembered that the linear shrinkage of M1 is 2.1%. Copper melts at a temperature of 1083°C, casting is carried out in the temperature range of 1150-1250°C.

M1 is produced in the form of cast (horizontal casting ingots, GOST 193-79) or deformed (wire rod, TU 1844-01003292517-2004; strip, GOST 1173-2006; annealed and pressed rod, GOST 1535-2006; pipe, GOST R 52318- 2005) semi-finished products. Rolled sheets must be subjected to bending tests. According to the standard, tape up to 5 mm thick must withstand bending until the sides touch. Thicker sheets (6-12 mm) are checked until the sides are parallel.

Semi-finished products produced by cold rolling are tested for bending at temperatures up to 90°C. Cold-deformed copper pipes (soft, semi-hard, hard) are produced using technology that does not affect further performance. They do not defrost and are resistant to rupture when liquid media freeze. Large cross-section pipes are manufactured using pressing technology.

Alloy M1 is used in cryogenic production. It is used to make current conductors, wire, rods and electrodes for automatic welding and gas welding of non-critical joints of cast iron and copper parts. M1 is the main alloy for the production of high quality bronze.

Copper alloy M1 is produced in accordance with GOST 859-2001. This material contains 99.9% copper, as well as other substances: iron, arsenic, nickel, zinc, sulfur, lead, oxygen, bismuth, tin and antimony. This is a highly plastic material with good corrosion resistance. It is highly processed and is part of the manufacturing process for many other metals.

The key alloying elements here are nickel and phosphorus. Copper alloy M1 can be oxygen-free, cathodic, deoxidized with phosphorus or oxygen. At the same time, according to technical parameters, hard and soft copper are distinguished. This alloy is used primarily in the automotive and aircraft industries, as well as in instrument making.
