German silver is not pure silver. It's actually an alloy comprised of varying ratios of nickel, copper and zinc; and is called nickel silver, paktong silver, or alpacca silver. Proper cleaning can be a challenge, as many cleaning products intended for use on pure silver will not necessaril...
The alloy is preferably clinging to a locating member comprising one of the metals and this then acts to replenish that metal. Replenishment of either metal may be by a controlled feed of pellets to the locating member where they melt in an aperture therein. After treatment may include passing...

A tin-bismuth solder alloy, with specified contents of silver, copper and nickel and/or germanium, is new. A novel solder alloy has the composition (by wt.) <= 21% Bi, <= 4% Ag, <= 2% Cu, <= 0.2% Ni and/or <= 0.1% Ge and balance Sn....
of acompoundfrom its cooling curve, which enabled him to explain systems of mixed crystals. Tammann conducted much research on the mechanical properties of metals during coldworking and found that changes in such properties resulted from a rearrangement of their crystals. This finding, together with...
