摘要

Procedure for obtaining gold alloys of different karats with the same preservation index of their tempering even after each one of them has been subjected one or more times to the action of the torch, characterized essentially by the fact of having any current alloy of gold previously determined for the manufacture of nibs for fountain pens 0 2% to 4% of a metal of much more hardness than the components of said alloy - gold silver and copper - and with a high degree of inoxibility or combination of metals that have said characteristics such as Tungsten Silicon Nickel Chrome or other appropriate and also being added when required the chromaticity of the alloy to obtain an adequate percentage of copper as a colorant, subjecting all this to the temperature corresponding to the melting point of the metal with the highest added hardness.
