Copper rods are manufactured in accordance with GOST 1535. For the production of them often is copper grades M1; M2; M3, which corresponds to the chemical composition of GOST 859. The bulk of the market takes a copper rod M1.
It is made by pressing a copper rod, hot deformation, cold deformation. The main advantages of copper bars: plasticity; corrosion resistance; durability; high electrical and thermal conductivity; It is a relatively easy to process. Articles made of copper because of its performance characteristics have been widely used in various industries and sectors of the national economy. Rod copper M1 is used in many areas: instrumentation, manufacturing equipment, structural components, parts, and so on; space and the aviation industry; and Metallurgical and metal-working industry; mechanical engineering; to the energy industry to create a heat-conducting structures, conductors, elements of buildings and so on; copper bar parts used in the manufacture of HVAC equipment, decorative items. Labelled copper rod M1, as well as all long products, indicate the brand, method of manufacture, material condition and other parameters. 1) A method of manufacturing: - D - drawn (cold-); - G - pressed (Hot). 2) Accuracy of manufacturing: - N - normal; - P - increased; - In - high. 3) cross-section form: - KR - round; - HF - square; - SH - hexagon. 4) The state of the material: - M - soft; - P - semi; - T - solid. 5) Length of the product: - ND - Random length; - CD - fold measured length; - BT - coils. Also, copper rod M1 may differ: - AB - for processing on automatic machines; - L - soft state copper rod increased plasticity; - P - semi-solid state of increased plasticity of copper rod; - Y - solid state of increased plasticity of copper rod. For example, DKRVT ND 15 AB M1 GOST 1535-91 indicates that the copper rod cold-M1, with a circular cross-sectional shape, with high precision manufacturing, solid, with a diameter of 15 mm, random lengths, for processing on automatic machines.
