MONEL

Monel or "Monel Metal" is the denomination for a series of corrosion resistant alloys with a 67% of Ni content and a 30% of copper content, with trace of Fe, Mn and other elements.

ALPACCA

Alpacca is the denomination for a series of alloys of Cu-Ni-Zn denominated also argentone or argentena, with Zn 15/30% and Ni 10/30%, having good mechanical properties and corrosion resistant. The presence of Ni makes enhances this properties and gives a silver look to the alloys.

In English is named Nickel Silver or German Silver.

The company Ramisa can find and deliver normal Alpacca scrap and special Alpacca alloys.

CONSTANTAN

Is an alloy with 44/46% of Nickel and 54/56 % of copper.
The constantan is an alloy characterised of a particularly stable resistivity at the temperatures change. Some times is possible to alloy it with a little percentage of Mn (1 %).

The constantan is delivered in wire icophoto or strips (0,5 x 300 x 2000 mm). icophoto
