PA24 German silver is just a trade name for a group of copper nickel and zinc alloys, the color can vary from white to nickle in color, and range in all hardnesses depending on preperation, some even commonly being used in watch springs.. German silver is graded according to its nickel content with "Extra white metal" being the highest grade. While this trigger guard is not of a high grade it has about the same tinsel strenght as a brass trigger gaurd.. While being worried about melting temps I used 95/5 in the repair and seemed to work amazingly well thanks for the help guys...
