Essentially, the filler materials that are to be used have been formulated to incorporate one of these ‘activating’ elements to form an intermediate layer on the ceramic.

During the brazing procedure the activating element reacts with the ceramic substrate to form a series of highly complex inter-metallic metallurgical phases thus being subsequently wet by the molten filler material. ABA’s should be brazed in vacuum or argon. If brazed in argon, the vapor pressure of elements such as silver should be taken into consideration when programing the peak temperature. ABA’s are best suited for furnaces. Fahrenheit Product Ag Cu Ti Ni In Sn Solidus Liquidus TIPS FOR BRAZING ABAs APA 1 98.4 .6 1738 1758 APA 2 96 4 1780 1780 1.

Flux removes oxides that form during the brazing process. Flux must be used when brazing unless in a controlled atmosphere. Fluxes are supplied in paste, liquid and dry form, including several for spray dispensing. We carry a wide range of flux and flux remover for every brazing and soldering application. P&I White Flux P&I Black Flux APPLICATION Brazing Filler Metal BAg, BCu Brazing Filler Metal BAg, BCu Temperature Range 1050-1600 F Temperature Range 1050-1800 F Flux can be applied in any number of forms Recommended Base Ferrous and non-ferrous Recommended Base Ferrous and non-ferrous including flux paste, powder or pre-made Metals alloys, stainless steels Metals alloys, stainless steels brazing pastes that combine flux with filler and copper and carbide metal powder. Flux can also be applied Application General purpose white Application High temperature black using brazing rods with a coating of flux, or brazing flux paste brazing paste flux; a flux core.

SOFT SOLDERS Soft Solder alloys are ideal for low temperature metal joining. Lead based and lead-free solders in over 100 different alloys available with solid, acid or rosin cores. Soldering flux also available.

P&I also has the ability to draw wire to Slitting capabilities provide customers with Brazing pastes are materials consisting of a customer requirements upon request width flexibility per unique application metal alloy in a powder form that is well mixed with a binder. A brazing flux is typically added to paste to provide protection from oxidation. Pastes can be custom made to customer requirements to improve productivity, repeatability and ease of use in joining applications. The major advantage of brazing paste usage is that it can be dispensed in accurate and controlled volumes. With this level of control, braze joints are able to receive the same amount of paste on each application. BRAZING PREFORMS

A Brazing Preform is any solid shape of filler that can be readily placed in an assembly prior to the heating cycle.

1. Elimination of costly hand feed operations. 2. Accurate control of brazing alloy volume resulting in fewer incomplete joints. 3. Provide access to automated brazing and soldering systems. 4. Uniform wetting and smooth joint appearance.

Preform Capabilities • Ring Coiling Wire Diameters: .005 to .187 all alloys • Ring Diameters: .030” I.D. to 13” O.D. • Straight Cuts and Slugs: .005” diameter to .750” • Stamping: Blanked washers, discs, shims and special shapes .001” thick to .100” thick • Four Slide: An infinite variety of configurations • Cold-Headed Parts: Spheres and Discs • I.P.S. Band Rings: To Naby Specifications RING COILING

P&I’s ring coiling department operates on an individual customer order basis. Each order is statistically controlled (S.P.C) to provide quality assurance to customer specifications.

• Lap Rings are formed with an overlap to allow compression “Cling” within the fitting.

• Gap Rings allow compression “Cling” where wire overlap is undesirable.

• Butt End Rings will not tangle, and lie flat without helix.

• Multi-Turn Rings are used when a joint requires a volume of filler that cannot be provided by a Single Turn Ring.

• Edgewounds are an economical alternative to a washer. They are made by winding flat wire on edge. STAMPINGS

Prince and Izant manufactures custom stamped preforms from over 1,000 tools already on our shelves. Chances are we have existing tooling to meet your specific requirements. If we need to develop new tooling, our precision in-house machine shop keeps cost and lead-time to a minimum.

• Slugs - Normally the most economical preform to manufacture. Slugs can be made from any brazing wire and cut to required length.

• Washers, Discs and Shims - Fabricated from brazing alloy strip and used where joint clearances or joint design prevent the use of wire forms.

• Multi-Slide Parts - Brazing wire and strip can be formed into an infinite variety of configurations to meet customer application requirements.

• Cold-Headed Parts - Primarily spheres and disc shapes. Used in joints of limited access that require a large volume of alloy. The Prince & Izant Companies 12999 Plaza Drive, Cleveland OH 44130 USA princeizant.com [email protected] +1 216.362.7000
