UPCAST® technology is best known for its use to produce oxygen free copper (Cu-OF) rod for electrical applications.


Oxygen free copper

UPCAST® produced oxygen free copper is single phase material with a mere 1-2ppm oxygen in it. The UPCAST® process delivers the cast product directly at its final size without any hot rolling involved. This eliminates the possibility of rolling induced inclusions and minimises the thickness of the surface oxide layer. These factors give UPCAST® oxygen free copper rod superior ductility in addition to its excellent electrical conductivity.

UPCAST® copper rod is well-suited for all electrical applications and has become the preferred feedstock especially for:

  • Fine and multi-wire drawing where ductility requirements are most demanding
  • Enamel wire production where surface finish is of utmost importance
  • Continuous rotary extrusion where tool wear rate is a crucial factor


The majority of UPCAST® lines produce rod – both Cu-OF and alloys. The most commonly cast rod diameter is 8mm – the industry standard for wire and cable. Bigger diameters are cast for manufacturing a variety of products e.g. bus-bars, trolley wires, electroplating anodes etc.


Tubes have been cast with UPCAST® technology already since late 70’s. The rather coarse grain structure attainable at that time restricted their use for the manufacture of fittings. However, now as the result of a highly successful development program it is possible to cast thin-walled tubes with a fine grain structure – UPCAST®-SGTube – suitable for sanitary and ACR tube production.

Alloyed coppers and copper alloys

Typical low alloyed coppers produced with UPCAST® are silver-bearing and phosphor-deoxidized coppers. When casting them in a double-furnace line an automatic alloy feeding system can be incorporated.

There is a wide range of copper alloys that can be cast with UPCAST®. These have traditionally included e.g. brasses and bronzes. As new applications for copper alloys are being developed and new types of copper alloys emerge the utilisation of UPCAST® technology within the copper alloys field is rapidly increasing.

For copper alloys, we recommend the use of separate furnaces for melting and holding to ensure stable and accurate chemical analysis in the cast rod. In these cases both the base metal and the alloying element or elements, are charged into the melting furnace in correct proportions while a homogenized melt is transferred into the holding furnace.

Consistent experience.

All this with reliability built on 40 years of consistent
development work, operational experience
and excellent customer service.

“UPCAST® technology in itself, has always been an environmentally friendly process. Just electricity, compressed air and a cooling water circulation are needed to keep the process running.“
