Active Alloys

ABAs combine braze alloys with active elements to allow for the direct joining of metal to ceramic. Active Braze Alloys are designed for brazing ceramics to metals as well as other nonmetallic components without the need for prior metallization of the contact surface.

Aluminum Alloys

Aluminum brazing filler metals are used to join brazeable aluminum base metals. Silicon and copper are typically added to pure aluminum to lower the melting range and provide a suitable joining material. Magnesium can also be added to aluminum to facilitate wetting.

Copper Alloys

Copper brazing alloys are well known for their excellent resistance to corrosion, high electrical conductivity, and high thermal conductivity and are generally used for brazing carbon and alloy steels, stainless steel, nickel, and copper-nickel. Copper alloys are ductile, wet iron appropriately, and exhibit excellent joint penetration. These alloys are primarily used in furnace brazing with protective reducing atmospheres without a flux. Flux may be required for metals that have constituents with oxides that are difficult to reduce.

Gold Alloys

Excellent corrosion resistance, flow, and wetting. Produces high-strength ductile joints and is suitable for applications with high service temperature requirements. The radiopacity of gold and its alloys facilitate braze joint inspection during nondestructive testing methods.

Platinum Alloys

Platinum is easily transformed into other shapes, such as rods, ribbon, and wire. And, since it is highly resistant to corrosion with a high oxidation temperature, it can withstand most environments without sustaining significant damage or chemical alteration. Platinum-Iridium alloys have the chemical stability of platinum with increased hardness due to the addition of iridium. Platinum-iridium alloys are ductile, malleable and versatile in their manufacturing capabilities. . Platinum-tungsten alloys are used for a range of medical applications due to its relatively high degree of biocompatibility and excellent fatigue resistance.

Nickel Alloys

Used for applications requiring high corrosion resistance and in high-temperature service applications. Common forms include powder, paste, tape, and foil applications.

Palladium Alloys

Used to braze a variety of materials from stainless to metalized ceramics. Good resistance to oxidation and high-temperature strength.

Silphos Alloys

Strong corrosion resistance. Phosphorus presence renders the alloy self-fluxing thus, these alloys do not require a flux when used to braze copper to copper. When brazing copper to brass or brass to brass, a white flux is needed.

Silver Alloys

Cadmium-free silver alloys can produce strong, ductile, and leak-proof joints at lower brazing temperatures than copper or nickel-based alternatives. Cadmium-bearing silver alloys are versatile due to wettability and are used for nearly all nickel, iron/steel, and copper-based alloys

Flux Products

Molten brazing alloys require a clean surface on which to flow if they are to bond properly. Heating metal during the brazing process causes oxide to form on its surface. These oxides, if not removed, will prevent the filler material from flowing completely. A coating of flux applied prior to heating the joint will protect the area from exposure to the air and absorb oxides, which may form on the surface.
