Preforms Capabilities:

Characteristics Make-Up:

Silver based Alloys Cadmium Free The following are general purpose brazing alloys, suitable to join easily a wide range of ferrous and non-ferrous base materials (steel, copper, brass, etc.).

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.

Silver based Alloys Cadmium Bearing The brazing alloys presented in this page are very versa-tile, high-strength, free-flowing and exhibit the lowest melting points of all silver based alloys.

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, bever-ages and/or human health in general is involved, is for-bidden.

We recommend to avoid the use of Cadmium Bearing alloys whenever possible and suggest their Cadmium-free substitutes.

NOTE: Alloys with 0,2 % Silicon are available.

Silver Based Alloys Special Applications The following are alloys that, thanks to the addition of spe-cific elements, or to their particular composition, have im-proved characteristics that make them suitable for specific applications or to operate in difficult conditions.

In particular the addition of Nickel helps in joining difficult-to-braze materials (such as stainless steel, tool steel, tung-sten 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.

Copper Sandwiched Alloys Trimetals Trimetals strips consist of two layers of silver brazing alloy clad onto a copper core and are very popular for brazing of carbides onto steel, especially large pieces.

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.

Copper Phosphorous Alloys The Copper-Phosphorous alloys are extensively used to join copper and copper alloy base metals (brass, bronzes).

They have self-fluxing properties when used on cop-per 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.

Brass and Copper Based Alloys This group includes four different categories of high-temp brazing alloys: - General Purpose Brasses

- 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 sup-plied 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.

These brazing alloys are generally used when specifications require good corrosion resistance and/or estreme temperature service properties (both high and subzero temperatures).

Ideal for brazing of stainless steel and ni-ckel based alloys.

They find numerous applications in manufacturing of heat exchangers, diamond tools, and high tech sectors such as aerospace industry.

Available in powder and paste form, brazing is usually performed under a protective atmosphere or under vacuum.
