Brazing Alloys

Flux-Coated Brazing Alloys without Cadmium

No need to add flux—these alloys have it built in.

Brazing Alloys without Cadmium

Use these cadmium-free alloys with most metals in general purpose applications.

Brazing Alloys with Cadmium

Use these alloys with most metals in general purpose applications.

High-Strength Brazing Alloys with Cadmium

These alloys create stronger bonds than standard brazing alloys.

Gap-Filling Brazing Alloys

These alloys melt into thicker liquid than standard brazing alloys, which allows them to fill larger gaps.

Brazing Alloys for Furnace Brazing

Brazing Alloys for Tight Gaps

When melted, these alloys form a thin liquid that easily flows into smaller gaps than standard gap-filling brazing alloys.

Corrosion-Resistant Brazing Alloys with Cadmium

Brazing Alloys for Joining Aluminum to Copper

Brazing Alloy Assortments

Start brazing with this assortment that includes alloy without cadmium for joining dissimilar metals, alloy without cadmium for copper and copper alloys, and a jar of flux.

High-Strength Brazing Alloys for Copper

These alloys create stronger bonds than standard brazing alloys for copper.

High-Strength Brazing Rings for Copper

Join copper tubing and tube fittings with a stronger bond than standard brazing rings for copper.

Brazing Alloys for Copper

Use these alloys for general purpose applications.

Gap-Filling Brazing Alloys for Copper

These alloys melt into thicker liquid than standard brazing alloys for copper, which allows them to fill larger gaps.

Brazing Alloys without Cadmium for Carbide Tool Inserts

Also known as trimetal brazing strips, these alloys have silver with nickel alloy sides and a copper core.
