APPLICATIONS

Cu-CATH

For semifinished priducts

It must be cast in the casting form for the following workings. It is used in the electric wires and in the valuable alloys productions.

Cu-OF

For the electronic industry and for needs of the highest cold plastic workability. For electric wires and valuable alloys.

Cu-ETP

Cu-DLP

For semi finished products which don’t require electric conductivity, but having a good plastic workability and free from brittleness phenomenon in an reducing environment.

Cu-DHP

Cu-LSTP

For semifinished products of castings

For  conductors in which the Ag highs the copper crystallization temperature.

Cu-HSTP

Cu-FRTP

With no needs of electric conductivity, good changeability and weldability, not fragile in a reducing environment if phosphorus oxidised.

Cu-DPA

High temperatures in an oxidative environment. Plates for furnaces and, generally, for thermic plants, burners, ecc. parts.
