High Purity Solder Alloys
Solid Solder Wire

High Purity Solid Solder Wire is manufactured from a grade of solder alloy with purity levels far exceeding the requirements of all national and international standards. Warton Metals manufacture all solid solder wires in High Purity Solder Alloys, using the finest virgin materials available world-wide.

Warton manufacture all alloys in accordance with: ISO 9453:2020, EN 29453, DIN 1707, BS 219, QQS 571E or to the customer's own specification.

Solid solder wire is available in gauges from 10swg (3.25mm) to 34swg (0.234mm).

Solid solder wire is available in lead free alloys with lead alloys available to professionals.
