PHP is specailized in supplying the remetling products with low Fe content in order to improve fatigue properties.
PECHINEY RHENALU is used to provide optimum solutions

As cast bars are produced using continuous casting for various application, mainly electrical applications

Aluminium electrolytic capacitors are made of aluminium anode and cathode foils.

Anode foils must have a high and consistent surface capacitance. They are made from high purity foils whose surface is increased by an electrochemical etching treatment.

Cathode foils are usually thinner than anode foils and do not require high purity aluminum.

PHP Froges is a leading producer of high purity plain foil especially suited for etching treatments producing anode capacitor foil. This foil can be delivered in different specifications including various thickness, composition and surface properties. Usage may be low, medium or high voltage capacitors.
Plain cathode foil can also be supplied.
Pechiney is a world leader for aluminum purification, hot and cold rolling processes which are critical for the manufacture of high quality capacitor foil .
