Copper in the M1E grade, defined in the European standard as Cu-ETP produced in the electrolytic refining process - cathodic remelted. It is characterized by high thermal and electrical conductivity, has high plasticity and impact strength. Cu-ETP copper is susceptible to plastic processing (especially in the annealed state), is susceptible to welding, brazing and soldering. Cu-ETP copper is very often used in industry - especially in the production of electrical and electronic components, in the production of cables and wires and in engineering applications.

Pure copper - The flat bar is not coated with any insulator. It serves as a semi-finished product in various branches of the economy.

Application: Jewelry, Artistic jewelry, Handicraft, Modeling, Electronics, Automotive industry, Automation, Welding
