Tungsten Alloy Jewelry&Watch&Toy Counterweight

Tungsten Alloy Jewelry&Watch Counterweight - Zhuzhou Jiuding Metal Technology Co., Ltd.

Tungsten Alloy Jewelry & Watch Counterweights are high-density eco-friendly embedded weighting parts independently developed and produced by Zhuzhou Jiuding Metal Technology Co., Ltd. This product category covers full-series standard and custom tungsten weighting solutions tailored for high-end fashion jewelry, plated ornaments and precision watch accessories, completely replacing traditional toxic lead counterweights.
We supply three core material grades with precise density tolerance: pure tungsten 19.1±0.15 g/cm³, non-magnetic W-Ni-Cu tungsten alloy 18.5±0.15 g/cm³, and cost-effective W-Ni-Fe tungsten alloy. All materials are lead-free, non-radiative, sweat-corrosion resistant and fully RoHS & REACH compliant, meeting cross-border export standards for Europe, America and other global markets.
Our product range includes tungsten balls, thin discs, sheets, rings, and hot-selling four-leaf clover shaped custom counterweights. Supported by professional powder metallurgy and precision CNC machining, all counterweights feature uniform density, stable weight without long-term drift, smooth burr-free surfaces, and optional polishing, sandblasting, gold plating and rose gold plating finishes. Available in non-magnetic and slightly magnetic options, these weights deliver realistic gold-like heavy hand feel with ultra-small volume, ideal for premium pendants, bracelets, clover-themed jewelry and precision watch case internal weighting. We support sample customization, small-batch trial orders and mass stable supply with complete certification documents.
