U.S. sourcing overview
POS61 is a regional designation for an antimony-free tin-lead solder used in electrical, radio, instrument and tinning applications. A quotation should be based on the exact governing standard, alloy composition, product form and flux requirement rather than the grade name alone.
Product forms and sourcing
Supply can be reviewed for round wire, solid rod, flux-cored tube, ingot, bar and powder, subject to diameter or particle size, flux system, packaging and quantity. State the required form, dimensions, spool or package size, flux percentage, cleanliness and any residue or process restrictions.
Evek LLC reviews each requirement against the requested grade, specification, form, dimensions and quantity. Availability, origin, production route, minimum quantity and certification are confirmed during quotation; website text is not a stock or compliance guarantee.
Specification and substitution
Solders with similar tin content can differ in impurity limits, melting range, flux compatibility, wetting behavior and regulatory suitability. The purchaser must confirm that lead-containing POS61 is permitted for the intended product, workplace and destination and approve any substitute.
The purchaser remains responsible for material selection, design approval and confirmation that the specified material is suitable for the finished component, manufacturing process and service environment.
