Available in many different presentation forms (rods, flux-coated rods, wires, strips, rings, preforms, pastes and powders), they are very free flowing, ductile and strong.

All these alloys do not contain Cadmium, do not present the Health & Safety concerns associated with Cadmium-Bearing Alloys and are compliant with the RoHS regulation.

They are divided in two categories: alloys with Tin, and alloys without Tin;
Tin being used to lower the melting temperature of the alloy.

When brazing in an oxidizing environment (that is: in air), the use of a proper flux is required.

They can be used to join a wide range of base materials.

Since Cadmium and its oxides are toxic, special safety precautions must be followed during brazing operations (e.g. mechanical ventilation and/or respiratory mask).

The use of these alloys in applications where food, beverages and/or human health in general is involved, is forbidden.

Cadmium bearing brazing alloys alloys have been banned in the European Union since December 2011 and their usage is no more allowed: please contact our technical and commercial staff to get and advice on selecting the most appropriate cadmium-free substitutes.

In particular the addition of Nickel helps in joining difficult-to-braze materials (such as stainless steel, tool steel, tungsten carbide, nickel and nickel alloys, etc. ) and improves corrosion resistance.

Manganese helps in brazing carbides.

Alloys without Zinc are suitable for brazing in oven (some are also suitable for vacuum brazing).

Alloys without Copper are ammonia resistant.

The copper core of the strip absorbs and relieves the stresses caused by the difference in thermal expansion between carbide and base metal, thus helping to prevent cracking.

They are available in standard 1:2:1 ratio, other ratios being available upon request.

They have self-fluxing properties when used on copper and may or may not contain Silver.

A flux is required when joining brass or bronze.

They are available in rods, wires, rings and preforms, pastes and powders.

Ag15CuP is also available in strip form.

Copper-Phosphorous alloys should not be used on ferrous or nickel alloys.

Powders are available in different grain sizes, from coarse to fine.

Pastes can be supplied with and without flux and with various metal content percentages.

To select the most appropriate brazing paste, many factors have to be taken into account, such as: materials to be joined, heating method, type of atmosphere, etc.

- Brasses with addition of Nickel
- High temperature Copper Alloys for special applications
- Electrolytic Copper

All these alloys are economical to use and can generally be supplied in a variety of forms (rods, wires, strips, preforms, powder and pastes).

General purpose brasses can be used for brazing and for the Oxy-Fuel Gas Braze-Welding process, with liquid flux spread through the torch flame.
