Platinum Plumb Solders are a breakthrough for professional jewelers working with high-purity platinum. Unlike traditional platinum solders that contain little to no platinum, these plumb solders are formulated with up to 95% platinum content, ensuring true plumb weight for manufacturing applications where legal purity standards must be met.

These solders directly address problems jewelers have faced for decades with older platinum solders, including porosity, poor seams, and weak color match. The result is a cleaner, stronger, and more reliable solder joint—ideal for high-end platinum jewelry production. Each solder is sold in sheet form weighing approximately 1 DWT.

Features

  • Formulated with up to 95% platinum for true plumb weight compliance
  • Reduces porosity and improves seam integrity compared to traditional platinum solders
  • Strong color match to platinum alloys for seamless, professional results
  • Available in three flow points to suit different manufacturing stages
  • Sold in sheet form for precise, controlled use at the bench
