Saw a “new” alloy at tucson, a 5% PT / 95% Ag mixture, selling at
about $20 per ounce over respective spot price. visually, looks
pretty much like fine silver.
starts at about 7200 brinell, heat treats to about 7800, melts at
normal sterling temps plus about 100 degrees.
would anyone use this in place of 14/18 kt white?
