Product Overview
99.99% Tin is an ultra-pure tin with a nominal composition of 99.99% Sn, refined to the highest commercially available purity grade with extremely low levels of lead, cadmium, antimony, and copper — the trace elements that most frequently contaminate standard Grade A tin and degrade performance in purity-sensitive applications. Applications requiring 99.99% tin include semiconductor and electronics manufacturing where trace metal contamination affects device reliability; pharmaceutical and food-grade tin chemical synthesis where heavy metal impurity limits are tightly regulated; electroplating bath preparation for high-purity decorative and functional tin plating where bath chemistry is critical; research and development applications requiring a certified pure tin reference material; and tin whisker studies where trace element effects on whisker growth must be controlled. Conflict-free certification and a certificate of analysis are supplied. Forms: 8-20 mesh shot, approximately 1 lb bars, approximately 53 lb pigs, and approximately 5 lb ingots to serve the full range of production and laboratory requirements.
