POS 61 and Sn60Pb40 solder requirements

POS 61 is a legacy tin-lead solder designation commonly associated with approximately 60% tin and the balance lead. Sn60Pb40 is a related composition description, but the names must not be treated as automatic equivalents without checking the governing standard, permitted impurities and ordered form. Tin-lead solder may be restricted in some products or jurisdictions; the buyer is responsible for confirming regulatory and end-use requirements.

Wire, rod and ingot enquiries

State the accepted designation and standard, required form, diameter or section, unit size, quantity and packaging. For solder wire, specify solid or flux-cored construction, flux type and content where applicable. Include liquidus and solidus requirements, impurity limits, test method, traceability and certificate needs. Evek LLC confirms available forms, origin, minimum quantity and commercial terms during quotation.
