Otto Frei Platinum Plumb Solders are a breakthrough for professional jewelers. Unlike traditional platinum solders that contain little to no platinum, these new plumb solders are formulated with up to 95% platinum, ensuring true plumb weight for manufacturing applications where legal standards must be met.
Platinum plumb solders address the 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.
