Sterling Silver, Fine Silver & Argentium Casting Grain By The Ounce

Part # 844-90 6 In Stock Weight -- lb / -- g
$98.75
Type： Sterling Silver

Description

Made with certified recycled precious metal. Our silver, gold and platinum is refined from certified recycled content rather than newly mined ore, through refiners audited by outside parties. How we source our metal

Casting grain for melting and pouring into investment molds at the bench, sold by the troy ounce (20 dwt) so you can buy exactly the weight a job needs.

Four alloys are offered, each formulated for jewelry casting with a different balance of purity, durability, and tarnish resistance. Sterling Silver is .925 silver with .075 copper and delivers traditional casting performance. Fine Silver is .999 pure silver for high-purity work. Argentium® 940 PRO is .935 silver with copper and deoxidizers, designed for modern investment casting with tarnish and firescale resistance. Tarnish-Resistant Sterling holds the .925 composition and adds deoxidizers to reduce tarnishing and firescale.

Features

  • Four alloy options to suit a range of casting requirements
  • Sold by the troy ounce (20 dwt) for precise, flexible purchasing
  • Sterling Silver at .925 silver and .075 copper delivers traditional casting performance
  • Fine Silver at .999 offers maximum purity for high-purity applications
  • Argentium® 940 PRO at .935 is designed specifically for modern investment casting with tarnish and firescale resistance
  • Tarnish-Resistant Sterling provides the .925 composition with added deoxidizers to reduce tarnishing and firescale

Notes

No silver alloy is completely non-tarnishing. Tarnish-resistant alloys require significantly less cleaning and maintenance than standard sterling, but some degree of tarnishing may still occur over time.

One cubic inch weighs approximately 5.457 troy ounces in sterling silver and approximately 5.525 troy ounces in fine silver.

Fabulous customer service.

Silver casting grain is silver casting grain. It's nothing special but they took care of me. Good care. I was in a lurch and they took the worry off my plate. I'm talking Otto Frei up to my students and jewelry making friend.

If you need someone to help you out, Otto Frei is where to go.
