Cobresa S.r.l. Unipersonale is specialized in manufacturing electro-mechanical parts in electrolytic copper from the drawing.

Our long experience in welding copper and copper alloys and continuous search for high performing materials and machinery, guarantee the best quality.
The main business is the production of plant and spare parts for high current conduction made of electrolytic copper, particularly for industrial arc furnaces used for steelmaking, like: Electric Arc Furnaces (EAF), Ladle Furnaces (LF), Electroslag Remelting (ESR, ESRR), Vacuum Arc Remelting (VAR), Oxygen Converters (LD, AOD, VOD), Blast Furnaces, Induction Furnaces, Heat Treatment Furnaces and Forge Furnaces.

We supply bus bars and bus tubes for power transformers and electricity production and distribution plants for the electricity industry.
Each item is produced according customer's designs and technical specifications. We follow each production step from the individual part to the final complete plant assembled and tested in our workshop.

Our plants are supplied complete with electrical insulation, stainless steel and carbon steel parts, anchorage nuts and bolts, flexible copper connection and anything else required for its operation.

We can supply both the complete plant or individual parts.
We make our technical expertise available to support customers during design in order to obtain the best performances.

Here are some examples our supply:

  1. Conducting electrode holder arms.
  2. Secondary circuits for electric arc furnaces and ladle furnaces in copper and aluminium.
  3. Forged copper tips for oxygen and gas insufflation lances.
  4. Complete insufflation lances for oxygen and gas in copper, carbon steel and stainless steel.
  5. Electrolytic copper contact pads for electrode holder arms.
  6. Electrolytic copper clamps for electrodes.
  7. Electrolytic copper cooling boxes for burners.
  8. Burners.
  9. Copper and tubular steel cooling panels for shells and roofs of electric arc furnaces.
  10. Crucibles for ESR, ESRR and VAR plants.
  11. Copper electrodes for ESR, ESRR and VAR furnaces.
  12. Mechanical machining.
  13. Stainless steel and carbon steel structures.
  14. Electrical connections.

Generally, we can supply any mechanical part according to the design.
We also supply maintenance services for damaged parts in our workshop or directly at the customer, if there are problems in transporting the item.

We purchase all semi-finished products used to manufacture our items from leading companies in copper and copper alloy production certified according EN 10204 3.1 and ASTM standards.

Cobresa is certified ISO 9001:2015 by TÜV Rheinland.
