Tin Alloys
Sn–Pb and lead-free tin alloy products traded for soldering, joining and specialised manufacturing—with composition-led supply and documented commercial execution.
Specified compositions for joining and manufacturing.
S.S. International trades tin alloys in selected Sn–Pb and lead-free compositions for qualified manufacturers, solder producers, metal processors and industrial buyers.
Composition, product form, flux requirement, packing and quantity are reviewed for every enquiry. The final chemistry and tolerances are governed by the agreed specification and producer’s certificate of analysis.
From traditional Sn–Pb to lead-free systems.
The portfolio covers common nominal alloy families and selected forms. Availability, tolerances and suitability must be confirmed for each end-use requirement.
Tin–Lead Alloys
Nominal Sn content from 10% to 90%, balanced with Pb according to the selected grade.
Lead-Free Alloys
Selected SAC compositions and Sn–Cu alloy options for approved applications.
Product Forms
Solid bars, ingots, solid wire, flux-cored wire and other agreed forms.
