High-density tungsten alloy bracelet counterweight

Our tungsten alloy bracelet counterweight blanks are sintered semi-finished workpieces specially developed for producing high-quality premium jewelry bracelets. Manufactured through powder metallurgy using non-magnetic W-Ni-Cu tungsten heavy alloy, these blanks feature ultra-high density, stable physical properties, non-magnetism and excellent machinability.

Jewelry manufacturers can directly perform CNC turning, grinding, polishing, surface plating, engraving and pattern carving on these blanks to craft high-end bracelets with a solid, weighty feel.

1. Non-magnetic W-Ni-Cu Tungsten Alloy
Zero magnetism, no magnetic interference, perfect for wearable high-end jewelry. WNiCu grade is customized for jewellery industry, different from magnetic WNiFe tungsten heavy alloy.

2. High Density & Premium Weight Feeling
High specific gravity delivers solid, luxurious weight sensation for bracelets, bringing unique wearing experience.

3. Excellent Machinability
Semi-finished blank state allows CNC machining, grinding, polishing, engraving and surface coating to realize diversified bracelet designs.
