This is because copper surfaces kill dangerous. Nordic gold composed of 89 copper 5 aluminium 5 zinc and 1 tin is a more recently developed aluminium-bronze alloy for coinage.

Zinc melts at 420C and boils at 910C so brazing using an oxy-acetylene torch and a copper-silver filler is a possible alternative to welding being capable of providing joints with adequate mechanical properties and without the porosity problems. The helium-argon mixtures are used for welding of thicker sections. The generation of zinc fume results in welds which are likely to be porous and consequently unacceptable particularly if autogenous welding is attempted.
