Metallurgical heritage of KME Group: industrial excellence and European tradition

Operating under KME Group S.p.A., the enterprise unites more than a century of advanced metallurgy, specializing in high-purity copper, engineered alloys and semi-finished metal products.

Formed through the union of historic German and Italian metalworks, KME has grown into one of the worlds premier manufacturers supplying precision copper solutions.

Its primary manufacturing operations span Osnabruck and Hettstedt in Germany, Serravalle Scrivia and Fornaci di Barga in Italy, alongside international processing facilities.

The groups engineering capabilities support critical infrastructure sectors worldwide, including electrical power generation, switchgear engineering, automotive manufacturing and architectural building construction.

Manufacturing standards: precision rolling, smelting and copper alloy development

KME maintains an integrated manufacturing cycle employing multi-stage refining that achieves cathode purity up to 99.99 percent with minimal dissolved gas content.

The production of cold-rolled strips, transformer ribbons and industrial foil takes place on specialized rolling mills equipped with continuous optical thickness gauges.

For high-strength copper-nickel and bronze alloys, engineers utilize vacuum induction melting and precision micro-alloying with tin, silicon and beryllium.

This rigorous metallurgical control ensures uniform grain distribution, superior fatigue endurance and stable electrical conductivity during continuous operation in high-current distribution equipment.

Technical selection of KME rolled strips, industrial tubes and busbars

Selecting copper materials from KME / KME Group requires thorough evaluation of mechanical, electrical and thermal requirements.

For low-voltage switchboards and transformer sub-stations, engineers specify solid KM Copper Bars based on rated current density and short-circuit electromagnetic stress limits.

In refrigeration circuits and industrial cooling equipment, technicians specify seamless Serravalle Copper Tubes (SANCO, WICU) offering calibrated diameters and smooth internal bore surfaces that resist hydrodynamic erosion.

For stamped automotive terminals and precision spring contacts, micro-alloyed strips are matched to specified temper grades and forming bend radii.

KME MICO mineral insulated fireproof cables for critical life safety circuits

Mineral insulated cables developed by KME under the MICO brand provide an uncompromising solution for critical fire safety systems, emergency ventilation fans and smoke extraction equipment.

The completely inorganic cable construction features pure copper conductors embedded in high-density magnesium oxide dielectric insulation enclosed within a seamless copper sheath, entirely devoid of polymers or flammable materials.

The cable maintains unbroken electrical power transmission when exposed to direct flames exceeding 1000 C for multiple hours without generating smoke. Factory brass cable glands and hermetic termination seals prevent moisture ingress into the dry mineral powder.

TECU architectural copper systems: exterior cladding and natural weather protection

The TECU architectural product portfolio from KME represents an enduring benchmark in metal roofing and ventilated facade construction, offering an operational lifespan exceeding one century across diverse marine and industrial environments.

Exposed to natural atmospheric conditions, copper develops a dense protective patina that permanently shields the underlying metal from weathering degradation. Architects select from natural pre-oxidized finishes including TECU Classic, TECU Patina, TECU Oxid, TECU Brass, TECU Bronze and TECU Gold.

For large-format panels, lightweight TECU Bond composite cassettes deliver exceptional panel flatness across high-rise modern structures.
