• 925 STERLING SILVER CASTING GRAIN •Our 925 sterling silver casting grain offers jewellers a reliable, high-quality material for custom casting applications. Each granule is precisely refined to ensure consistent alloying, excellent flow characteristics, and minimal porosity during the casting process. Available in bulk for professional use, it's ideal for jewellers seeking reliable, ethically sourced silver for casting projects that require precision, durability, and a professional finish. • KEY POINTS •[Solid 925 sterling silver][Ready for lost-wax casting][Excellent fluidity and minimal shrinkage][Ethically sourced and lab certified][Consistent composition and melt quality] • MORE INFO •This casting grain consists of a 92.5% silver content alloyed with 7.5% copper, resulting in the standard sterling silver formula that balances workability, strength, and aesthetic shine. The grain is free from contaminants and refined to promote optimal melt behaviour. It is especially suitable for batch production, artisanal workshops, and custom fabrication processes. The uniform size and shape of the granules help achieve an even, controlled melt and reduce oxidation. • METAL SPECIFICATIONS •[Sterling Silver][Purity: 92.5% Ag, 7.5% Cu][Density: 10.39g/cc][Melting Range: 805–890°C][Hardness HV (Vickers): 70][Hallmarked: N/a] • USAGE & APPLICATIONS •Ideal for lost-wax casting, custom jewellery design, and alloy blending. Whether you're casting rings, pendants, or intricate charms, this grain provides a clean and predictable result with strong mechanical properties and bright polish potential. Use in a controlled environment with proper flux and crucible to maximise finish quality and metal yield.
