Endless variety of grades
Whether for cable strips, industrial pipes or mechanical engineering: Aurubis offers the right material for every application. We have our own, very good copper supply and profit from the advantages of a large group. At Aurubis, as an integrated copper producer, the entire process takes place in our own facilities, from smelting the raw materials through to manufacturing continuous cast shapes. This guarantees top quality and the best possible service to you as a client. We offer the following grades:
- Oxygen-bearing copper
- Oxygen-free copper
- Phosphorous-bearing copper
- Silver-bearing copper
- Low-alloyed copper
Oxygen-bearing grades (Cu-ETP1)
These copper grades display a very high conductivity of more than 100 % IACS. Their reformability and recrystallisation properties are very good. However, because of the typical oxygen content of 100 to 300 ppm, Cu-ETP1 is not resistant to hydrogen embrittlement. Oxygen-bearing copper is primarily used in electronics, electrical and mechanical engineering:
- Cable strips, lead frames, industrial strips, transformer strips
- Bus bars
- Commutator segments, matrix material for superconductors
See the complete chartOxygen-free grades (Cu-OFE)
Oxygen-free copper grades are melted and cast in a special process in the absence of oxygen. Apart from their good conductivity, they are at the same time hydrogen resistant and display good reforming behaviour. Typical applications include:
- Conductors for electronic and electrical applications
- Waveguides
- Cavity resonators
- Switches, contacts, base and terminal pins
- Cable strips for underwater cables
- Vacuum seals and anodes for vacuum tubes
- Matrix materials for superconductors
- Components for radar equipment
See the complete chartPhosphorous deoxidised grades (Cu-PHC, Cu-HCP)
These copper grades are deoxidised by means of careful doping using phosphorous, making them hydrogen resistant while at the same time having high electrical and thermal conductivity. In addition, they have good welding properties and robust processing properties. The preferred areas of use are in electrical, electronic and mechanical engineering:
- Conductors for electronic and electrical applications
- Switches, contacts, base and terminal pins
- Commutators
- Moulds for continuous casting
- Pressure vessels
- Current, bus and conductor bars
See the complete chartPhosphorus-bearing grades (Cu-DLP, Cu-DHP, Cu-DXP)
These copper grades contain residual phosphorous, which makes the material hydrogen resistant even during annealing. They have excellent formability and are therefore preferred in the following areas:
- Industrial pipes for HVACR applications
- Conduits
- Facades and roofing in construction and architecture
- Surface technologies
- Electrodes, solder
