100% recycled material 3N Polish tin ingots (Low Lead Tin Ingots) | Low lead specification suitable for electronic materials
Tin (Sn) is a non-ferrous metal with excellent ductility, re-meltability, and corrosion resistance, making it an essential foundational material in the fields of solder, electronic materials, and metal processing. This product is a recycled tin ingot of 3N grade (Sn 99.95% or higher) produced in Poland, with raw materials sourced 100% from recycling. No mined materials are used; only recycled materials such as electronic component scrap and metal scrap are collected and re-refined. Through distillation and refining processes, it achieves a low lead specification (Pb below 50ppm), demonstrating high wettability and processing stability for electronic materials and solder applications. It has a proven track record primarily in Europe and is suitable for applications that prioritize being China-free and having a high recycling ratio. Additionally, it features stable fluidity during re-melting, which helps suppress slag generation. Chemical analysis is conducted for every batch, and a quality control system is in place. It can flexibly accommodate everything from research and development applications to mass production scales, and it is increasingly adopted across a wide range of fields as a circular tin material that balances environmental considerations with high reliability.
