The Lomelt Series Brazing Flux range by JO FLUX® is made for silver brazing across a wide range of metals, filler alloys, and heating methods. The range has 8 flux products in powder and paste forms. They have active working temperatures ranging from 450°C to 870°C, which provide fabricators with the option of low, medium and high-temperature brazing work. The applications that are supported by these fluxes include steel, stainless steel, copper, copper alloy, nickel, nickel alloy and carbide.
Lomelt® offers different grades for different brazing conditions. Each grade has its own activity range and product form. This helps users select a flux that fits their filler alloy and heating process.
The range includes:
Lomelt A: General-purpose powder with a 500–800°C activity range.
Lomelt 58: Paste flux with a 565–870°C activity range.
Lomelt Flux Powder: Low-temperature powder active from 450–750°C.
Lomelt 50: Low-temperature paste active from 500–775°C.
Lomelt 55: Medium-temperature paste/powder active from 550–800°C.
Lomelt 59: Medium-temperature flux for extended heating cycles.
Lomelt B: Powder flux with a 600–870°C activity range.
Lomelt 60: High-temperature paste for furnace and induction brazing.
Our Silver Brazing Powder Flux range supports controlled application in many metal-joining processes. Lomelt A, Lomelt Flux Powder, and Lomelt B provide powder options across different temperature ranges. These grades can support good capillary action and filler metal flow when matched with the right brazing alloy.
Key features include:
Powder grades for different working temperatures
Good fluidity and capillary action
Options for steel, copper, stainless steel, nickel, and alloys
Compatibility with BAg and BCuP group filler alloys for selected grades
Lomelt Flux Powder can be mixed with water to form a paste
The choice of powder depends on the filler metal, base metal, joint design, and heating cycle.
Lomelt® paste fluxes offer a practical option for jobs where controlled placement matters. Lomelt 50, Lomelt 58, Lomelt 59, and Lomelt 60 cover different temperature and process needs.
These grades can be selected for:
Flame brazing
Induction brazing
Furnace brazing
Tight-fit and loose-fit joints
Short and extended heating cycles
Steel and stainless-steel components
Copper and copper-alloy assemblies
Nickel and nickel-alloy applications
Selected carbide brazing work
Lomelt 55 offers resistance to overheating, while Lomelt 59 supports extended heating cycles. Lomelt 60 is suited to furnace and induction processes where higher temperature and longer flux stability are needed.
The Lomelt range gives users a broad 450–870°C activity window. Lomelt Flux Powder and Lomelt 50 are both low-temperature grades. The medium-temperature ones are Lomelt 55, Lomelt 59 and Lomelt B. Lomelt 58 and Lomelt 60 address higher temperature needs.
The grade choice assists in maintaining the flux in the brazing process. The flux should match the working temperature of the filler alloy and the base metal being joined.
JO FLUX® is a Silver Brazing Flux Manufacturer focused on fluxes for brazing, soldering, and metal joining. Our Lomelt® Series combines different powder and paste grades for varied industrial requirements. The range is designed around practical process factors such as temperature, filler alloy, base metal, heating method, and joint fit.
For production teams, the Lomelt® range provides multiple flux choices within one product family. This makes it easier to select a grade for the required brazing process instead of using one flux across different applications.
After brazing, flux residues should be removed. Residues from these fluxes can be corrosive, so cleaning with hot water and brushing is recommended for the relevant grades.
