Tin Germanium Master Alloy

Allows for easy introduction of high-temperature Germanium to much lower-melting temperature tin-based alloys. Using DKL Tin Germanium Master Alloy is a cost-effective method of introducing Ge to tin-based alloys as using pure Ge may lead to solution and segregation issues. This Master alloy is used predominantly in mass production of high-grade electronic solders such as Nihon Superior SN100C (and the many imitations that have followed).

Our Tin Germanium Master Alloy is made only from 99.9% virgin tin and Germanium, giving a dependable and consistent analysis.

Available in 1% Germanium, balance tin.
