SN100C BAR TRIANGLE 2.5 lbs. BAR SOLDER

SN100C Lead‑Free Bar Solder — 2.5 lb Tri-Bar

SN100C is a next‑generation, lead‑free solder alloy originally engineered by Nihon Superior (Japan) and trusted in high‑volume commercial production since 1999. Unlike standard tin alloys, this material is NOT pure tin — it is a precision‑formulated blend of 99.3% tin, 0.7% copper, and trace additions of germanium and nickel. These micro‑alloying elements dramatically improve performance, stability, and long‑term reliability.

SN100C is widely recognized as one of the most user‑friendly and cost‑efficient lead‑free alloys on the market. Its unique tin‑copper‑nickel‑germanium chemistry delivers:

Exceptionally smooth, bright, and low‑dross solder joints

Superior wetting and flow characteristics compared to standard SAC and SnCu alloys

Reduced copper dissolution, extending pot life and minimizing maintenance

High‑throughput performance proven across wave, selective, and hand‑soldering applications

Lowest cost of ownership among major lead‑free alloys due to reduced dross and longer bath stability

For more than two decades, SN100C has been the go‑to alloy for manufacturers who demand consistent results, clean joints, and long‑term reliability without the cost penalties of silver‑bearing solders.

Ideal for: Wave soldering • Selective soldering • Bar replenishment • Lead‑free manufacturing • High‑reliability assemblies
