Melchior (alloy) corrosion in air, freshwater and seawater. Increasing content of nickel iron or manganese improves corrosion and cavitation resistance, especially in sea water and atmospheric water vapor. The alloy of 30% Ni, 0.8% Fe, 1% Mn and 68.2% copper is used in maritime shipping, in particular for the manufacture of condenser tubes. Thanks to the nickel, melchior, unlike brass and bronze, has not a yellow but a silver color. Together with high corrosion resistance, this silvery color is preferred for the manufacture of household utensils. Melchior (alloy) In metallurgy, melchior is an alloy of copper, mainly with nickel (5–30%). Its name
Fish and Tin and Copper and Dancers, was set to the song Fish and Tin and Copper. The group had originally performed it as a demonstration dance at the opening ceremony of Lowender Peran in 1997.
