Cooper band M1 has been widely used in mechanical engineering, electrical engineering. It is used in the development of highly efficient heat removal systems due to its excellent thermal conductivity. Brass bands are used as decoration elements in construction.
Production of copper from a cold-rolled strip takes place marks M1 Cu (r) and M2 (r), M3 (p) by rolling the blank into a long strip of rectangular cross section and must comply with GOST 495-92. On the strength characteristics of the copper strip may have a hard, soft or semi-solid state. Also brass band is classified in terms of accuracy of geometrical sizes: normal accuracy on both counts, the accuracy of the normal width and increased thickness, normal accuracy in thickness and increased in width accuracy, high precision on both counts.
Standard sizes of copper GOST 495-92 band are as follows. A copper strip across the width is made from 40 mm to 600 mm, and the thickness of 0.4 to 60 mm. The length of the strip usually ranges from 500 mm to 2000 mm, and the strip produced but random lengths.
What is the difference M1 copper grade of M2 or M3? Compared with them, the M1 copper grade is better due to the percentage of the base metal. Therefore, M1 copper strip has a high ductility, not exposed to corrosive media, and as has already been announced, and has high electrical conductivity.
