Platinum 95% Ruthenium 5%
950 Platinum Ruthenium (950PtRu) is the most widely used platinum jewelry alloy in the United States. With hardness of 130 Vickers, it is malleable enough for easy setting but strong enough to stand up to daily wear. Its natural white color is nearly identical to platinum iridium alloys often seen in antique jewelry.

Pro Tip: 950PtRu has a greater tendency to form porosity during casting than most other alloys, but this is easily healed through Hot Isostatic Pressing (HIP).
