High purity of 99.0% or more! Brazilian tin ingots that achieve both stable supply and excellent re-dissolution properties | Ideal for electronic components, solder, and plating applications.
Tin (Sn) is a non-ferrous metal with a silvery-white luster, high ductility, re-meltability, and corrosion resistance, making it an essential material in a wide range of industrial fields such as solder, bronze, and plating applications. This product is Grade B (purity over 99.0%) ingots sourced from Brazil, designed in a manageable shape of 20-30 kg units. Impurities such as lead, copper, and iron are strictly controlled, ensuring excellent fluidity and oxidation stability during re-melting and casting. It exhibits high wettability and processing stability, particularly in electronic components, solder alloys, and tinplate, minimizing slag generation during the re-melting process. Chemical analysis (ICP/OES) is conducted for all lots, and quality assurance is performed at an ISO-certified factory. Additionally, an environmentally friendly process utilizing recycled metals is adopted, contributing to CO₂ reduction. We have established a flexible system capable of accommodating everything from research and development to mass production, and as a high-quality, reliable, and environmentally friendly tin from Brazil, demand is expanding across the electronics, metals, and chemicals sectors. Moreover, its adoption as a highly reliable material in the automotive, semiconductor, and electrical fields is progressing, making it a material adaptable to global supply chains. It is also optimal for long-term supply with stable quality and compliance with environmental regulations.
