A Critical Piece to the Brazing and Soldering Process: FluxBrazing flux is critical to the brazing and soldering process because it minimizes the oxidation that may form on both the brazing filler metal and the materials being joined. Numerous formulations of flux are available for virtually all metal joining operations. Lucas-Milhaupt Fluxes Meet Every Need and Specialized ApplicationThe majority of common brazing applications are readily met by HANDY FLUX, the general purpose flux that has remained an industry standard for over 70 years. It is a powerful general purpose flux that protects your parts up to 1600F (871C). We also offer fluxes for virtually every specialized application including formulations for high temperature and low temperature applications, furnace and induction brazing, as well as those for automatic flux dispensers.

Lucas Milhaupt carries pre-packaged brazing filler metals, fluxes, and solders, including SIL-FOS. SIL-FOS, the original copperphosphorous brazing alloy, was developed and patented by Handy & Harman in 1931. Distribution Pre-packaged ProductsAvailable either in bulk or pre-packaged lots are filler metals for brazing copper-based alloys (SIL-FOS), steels, stainless, etc. (SILVALOY and EASY-FLO Alloys), as well as low temperature, lead-bearing (SOLDERITE) and no-lead solders (SILVABRITE).

Lucas-Milhaupt and Handy & Harman rank prominently among the worlds leading producers of brazing and soldering filler metal materials and technology. Over 75 years ago, Handy & Harman developed and patented many of the standard brazing and soldering products that are still in use today. Save on Operational Costs, Increase Profitability with Our Brazing Filler Metal AlloysThe following brazing alloys and soldering alloys are available in a wide variety of forms including wire, rod, preformed rings, and foil. They are also available in atomized powder for blending with binder systems for making pastes. By fabricating these materials into a variety of engineered forms, we enable customers to improve their metal joining operations by reducing overall metal-joining costs and improving productivity and quality.

To eliminate the need for separate fluxing, these brazing materials are either cored or coated with a brazing flux. HANDY ONE is a flux-cored brazing material that offers numerous advantages compared to traditional metal-joining methods. It is composed of a brazing alloy in strip form rolled around a powdered flux. A variety of different filler metals and fluxes are available depending upon your temperature requirements and materials to be joined.

In addition to traditional brazing & soldering filler metals and fluxes, we offer complimentary products and unique, specialized products for use in your joining operations. Omni Stop-Off is a brazing aid used to prevent the flow of flux and metal to unwanted areas during brazing. Omni Stop-Off is commonly used in aluminum and silver brazing. Flux coated shims are a new innovative product for brazing difficult joint configurations. Omni Technologies flux coated shims can be used for any butt joints, saddle joints, or schrader valves. Aluminum flux coated shim eliminates pre-fluxing issues associated with conventional washers, pre-depositing of paste alloy, or a difficult wire feed operation.

We have the ability to roll your strip thicknesses not available directly from the mills. This customized service can yield strip in widths up to 6" (152.4mm) and thicknesses down to .001" (.025mm).

Manufactured by high speed machines, rings maintain a true radius and may be partial turn, full turn or multiple turn. Rings inside diameter can range from 12" down to .040" and wire diameters from .125" to .008".

With our extensive inventory of dies, we can respond quickly to your needs. We have over 4, 000 dies available for top-quality stamped parts. We also have the ability to produce custom dies for your application. Our craftsmen produce simple, compound or progressive dies, utilizing high precision equipment to manufacture washers, discs, perforated strip and irregular configurations.

Carbide and diamond dies produce wire diameters from .187" to .005" (4.75mm to .127mm). The ability to draw wire enables us to provide the optimal size filler metal for incorporation into your assemblies. You do not need to waste money and material by brazing with stock sizes of material that may be too large for your assembly. Drawing also yields round, square, half round, rectangular or unusual cross sections.
