Otto Frei's Plumb gold solders are the same gold content as marked. That means, as opposed to repair solders where gold content is purposely lower than the mark for ease of use, these solders contain the plumb standard, or 14k (.585) gold if marked 14W H for example. These solders are for manufacturing when gold quality standards must be maintained.  Keep in mind that plumb solders flow at higher relative temperatures than repair solders.

All of these solders are Cadmium free.  All of these solders are nickel based white gold solders.
