M1 copper ingots

M1 copper ingots

Cooper ingot M1 brand used in the production of rolled copper, current conductors, parts of cryogenic equipment, and more. The chemical composition of grades of copper GOST defined 859-2001. M1 comprises Copper at 99.95% of copper, 0.003% of oxygen; 0.002% phosphorus, plus other impurities. Permissible content of impurities in the material to 0.01%. The main property of the M1 copper - high conductivity, as the proportion of impurities is negligible. M1 Copper has a specific electrical resistance at 20 � C equal to 0.01724 mO * m. Subject to appropriate quality copper M1 is characterized by good resistance to corrosion and temperature extremes, excellent ductility. At 20 � C copper M1 has the following properties: - thermal conductivity - 387 W / (m

 

  • deg); - Density - 8940 kg / m3; - Specific heat capacity - 390 J / (kg
  • deg). Casting and technological characteristics of the material: casting temperature from 1150 � C to 1250 � C, melting point - 1083 � C, while linear shrinkage of 2.1%. The hardness of hard and soft alloy according to GOST 1173-2006 is HB 10-1 = 45 MPa and HB 10-1 = 95 MPa, respectively. The coefficient of friction with lubrication is 0.011, no - 0.43. Subject to manufacturing technology copper M1 elongation ? is 30%. M1 corresponds Copper Cu-ETP1 marks, Cu-ETP, E Cu57, Cu-FRTP, SE-Cu, Cu-FRHC, E-Cu, E Cu58, produced according to different standards. CH ingots produced in (non-removed layer top surface) or CS (remote layer) horizontal casting. Pig should be smooth. Distortion along planes be within 0.8% of the length. The surface of the copper ingots must be clean, free of mechanical flaws and unnecessary inclusions, with rounded upper edges of at least 5 mm (possibly removal of the cutter).
