yet more precious metal alloys to confuse and annoy

[scrounger d detector collector]

well its been mighty tuff this year what with titanium,steel

and others found.

i try and keep up with current trends and here from a

recent jewelry catalog. comes

ARGENTUIM SILVER WHICH I GUESS IS BETTER

THAN sterling reduced copper content.


HONEYDIUM- A RICH HONEY COLORED blend of metals
w over 50 per cent silver. dont say what the other metals are.-


VALADIUM NO INFO ON

just when i thought i was learning about jewelry

now this ugh

Argentium sterling silver is a modern sterling silver alloy which modifies the traditional alloy (92.5% silver + 7.5% copper) by replacing some of the copper with the metalloid germanium. As it retains the 92.5% silver content of the traditional alloy, it is still referred to as sterling silver.

Argentium silver is the result of research by Peter Johns at the School of Art & Design, Middlesex University. The project began in 1990 with research on the effects of germanium additions to silver alloys. Germanium was discovered to impart the following properties to sterling silver:

Firescale elimination
High tarnish resistance
Precipitation hardening and simple heat-hardening properties
Increased ductility
Increased thermal and electrical resistance (making alloys suitable for welding and laser forming)
Environmental advantages (associated with not having to remove or plate over firescale)
Many of these properties significantly affect the traditional methods of working silver. For instance the absence of firescale eliminates tedious and time-consuming steps required by the silver worker using traditional sterling silver. It also eliminates the need for plating the final product which is often done on manufactured items because of the problems introduced by firescale. Tarnish resistance is of significant importance to both silver workers and the wearer of silver jewellery.

Argentium silver is patented and trademarked by Argentium Silver Company, UK.

[edit] Physical properties
Traditional sterling silver has a solidus melting temperature of 1475°F (802°C) and a liquidus flow point of 1650°F (899°C). The solidus melting point of Argentium sterling silver is 1410°F (766°C) and a liquidus flow point of 1610°F (877°C).

NICE REPLY on the one.

anyone know anything about the other 2 ?

Valadium is apparently a `fine` stainless steel (whatever `fine` means). Honeydium is a mix of silver, copper, zinc and indium (no %s defined).
