UPMR unveils Sterlium® sterling silver casting grain

Print

United Precious Metals Refining (UPMR) is pleased to introduce Sterlium®, their latest Germanium-based sterling silver casting grain.

Sterlium® is a patented formulation specifically created, based on the demands of the silver jewelry industry for premium tarnish resistance and a snow-white color.   This casting grain is formulated with the element Germanium and other additives, to provide excellent metal fluidity, greater surface hardness for luster and high metal re-usability.  The “spring effect” provided by this metal helps in securing gemstones firmly in place and the whiteness of the metal enhances the brightness of the gemstone.

Sterlium® sterling silver casting grain is recommended to be used in automated or enclosed casting machines.

For more information on Sterlium® or any additional products contact a UPMR representative at 800-999-3463, This e-mail address is being protected from spambots. You need JavaScript enabled to view it or visit www.unitedpmr.com.
