99.999% Pure and Alloyed Al Refined Products
5N products are mainly produced using vertical continuous casting as alloyed materials with an ultra pure basis for the semiconductor industry. Ingots, billets, wires and rolled plates are obtained.

5N5 Aluminum Alloys for sputtering targets (GIGALLOYS 98)
  • Main features of GIGALLOYS 98
    Low impurities content
    Uniformity of composition of alloying elements within the whole ingot
    Homogeneity of the fine grain size (PECHINEY patent)
    Low hydrogen content
    Low content of inclusions
    Low alpha emitters (U, Th) content
  • During several years, PHP has developped new processes and products in order to answer and sometimes anticipate the end users concerns. In order to understand the correlation between the use of our sputtering targets and the steps of manufacturing processes, we propose the total traceability concept with the GIGALLOYS 98 generation

    5N Pure and Alloy Ingots for sputtering targets
    The GIGALLOYS 98 generation is now delivered with the total traceability, available on the PHP extranet.

    5N Miscellaneous
    Several niche markets for 5N material need very specific pure and alloys either for the composition control or the shape. PHP is known for helping the most demanding customers in their market.

    Electrorefining
    Electrorefining (the 3 layers process) is used for refining aluminum for 4N and 5N materials

    5N pure and alloyed Aluminum wires
    Bars, wires and rods are extruded from billets of 5N pure and alloys
    Various dimensions are available : 5 mm (in coil 22 kg) , 9 mm, 40 and 50 mm diameter

    Nuclear Industry
    Nuclear industry is supplied with extremely pure aluminum (5N8 to 6N5) for special applications with very low emitters contents.
    Shapes and dimensions are made on special requirements.

    PECHINEY HIGH PURITY
  • PHP is a worldwide provider of High Purity Aluminum products. Purification, alloying and continuous casting are the main issues of PHP.
  • Purity levels go from high grade Al 99.95% (3N5) for reflectors through 99.99% (4N) for the capacitor market up to 99.9995% (5N5) for the integrated circuits (sputtering targets)
  • Pechiney High Purity is the only worldwide producer who can guarantee traceability for its high purity metal from ore extraction down to the sale of its ultra-pure billets.
    PHP is a division of ALUMINIUM PECHINEY with 100 people between 3 plants:
