Solder Compositions Most solders are based on the coloured gold-silver-copper alloys with additions of low melting point metals such as zinc, cadmium, tin and indium to lower the melting range. These additions will tend to whiten the solder alloy and so usually the copper content needs to be increased to compensate.Click to see full answer. Also to know is, can you solder gold with silver solder?When soldering two dissimilar metals together, use the lower temperature metal for soldering. For example, when soldering silver to gold, use silver solder. Using soft or repair solder when sizing.Also Know, what type of solder is used for jewelry? Silver hard solders work for assembling silver jewelry and can also be used to fuse brass and/or copper (as long as you don’t mind the joints being a different color). People also ask, is there gold colored solder? Easy solder paste for use on gold filled, brass, copper, and bronze metals. When polished it puts a bright rich yellow finish without the need for yellow gold plating (raw solder line will appear slightly gray). The solder is cadmium free and comparable to a medium silver solder flow temperature.Is soldering gold the same as silver?Gold solder is available in different colors to match various alloys. Because brass and copper solder, also known as brazing rod, has a high melting temperature and is brittle, silver solder is usually used on these metals as well as on silver.
