99/1 Tin-Copper Solder

99/1 tin-copper solder is a lead-free alloy under ASTM B32, formulated for soft soldering on copper pipe and fittings when the project requires avoiding tin-lead alloys. It is a technical and economical option for plumbing, sanitary maintenance, copper networks and capillary joints requiring compatibility with copper fluxes and good filler stability. It differs from 95/5 tin-silver because it does not incorporate silver, which normally positions it as a lower-cost alternative; and from 95/5 tin-antimony because the alloying element is copper, not antimony. The project specification, fluid type and installer's procedure must define whether this alloy is appropriate.

Selection guide

• Choose 99/1 for copper installations requiring lead-free soft solder.
• Compare with tin-silver if the project requires higher mechanical or thermal performance.
• Avoid mixing soft soldering procedures with silver brazing.
• Confirm packaging and compatible flux before starting installation.

Use recommendations

• Clean tube and fitting until the surface is bright and free of grease.
• Apply a uniform layer of flux compatible with the alloy and base metal.
• Heat the fitting, not only the wire or bar, to promote capillary action.
• Let it cool without movement and perform a leak test according to the installation protocol.
