Lomelt A Silver Brazing Flux Powder is a high-activity flux formulated for brazing operations using silver-based filler alloys, especially where strong oxide removal is essential. Designed for use within a working temperature range of 600C to 850C, it offers excellent performance in joining both ferrous and non-ferrous metals, including copper, brass, mild steel, stainless steel, and nickel alloys. The fine powder form allows for easy mixing with water or alcohol to create a smooth paste suitable for brush, dip, or spray applications. Lomelt A flux efficiently dissolves surface oxides and ensures optimal wetting and capillary action of the filler metal, resulting in strong, clean joints with minimal porosity. It adheres well to vertical and overhead surfaces during heating and produces a residue that can be easily cleaned with hot water or mild alkaline solution. Commonly used in HVAC, electrical assemblies, refrigeration systems, and general metal fabrication, Lomelt A is ideal for torch, furnace, or induction brazing processes requiring high joint integrity and repeatable quality.

Lomelt 55 Silver Brazing Flux Powder is a versatile, medium-activity flux designed for brazing with silver-based filler metals in a temperature range of 550C to 800C. Supplied in fine powder form, it is ideal for mixing with water, alcohol, or other suitable carriers to create a paste for brushing, dipping, or automated application. This flux efficiently removes surface oxides and promotes smooth, uniform flow of the filler alloy, ensuring strong, void-free joints. It is suitable for use on copper, brass, mild steel, stainless steel, and other ferrous and non-ferrous metals. Lomelt 55 is commonly used in HVAC assemblies, electrical components, plumbing systems, and general metal fabrication. After brazing, the flux residue is water-soluble and should be cleaned to prevent long-term corrosion. Its consistent performance and ease of application make it ideal for both manual and production-level brazing operations

Lomelt 57 Silver Brazing Flux Paste is a high-performance, medium-activity flux specially formulated for use with silver-based filler metals across a wide range of brazing applications. Active in the temperature range of 550C to 800C, this flux paste ensures efficient oxide removal and promotes excellent wetting and flow of the alloy, resulting in clean, strong, and leak-proof joints. Its smooth paste consistency allows for easy application by brush, syringe, or dipping, making it suitable for both manual operations and automated production processes. Lomelt 57 is compatible with ferrous and non-ferrous metals such as copper, brass, mild steel, stainless steel, and nickel alloys. It adheres well to surfaces during heating, resists spattering, and leaves a minimal, water-soluble residue that can be easily removed post-brazing. Commonly used in HVAC systems, plumbing, electrical assemblies, and precision instruments, this flux delivers reliable, high-quality brazed joints with consistent performance.

Aluminium Brazing Flux Powder is a high-activity, non-corrosive flux formulated to facilitate clean and efficient brazing of aluminum and its alloys. Composed primarily of fluorides and chlorides of alkali and alkaline earth metals, this powder flux effectively removes aluminum oxide layers and promotes wetting of the brazing filler metal. It enables strong, void-free joints at typical brazing temperatures ranging from 500C to 600C. The fine powder form allows for easy application by brushing, dipping, or spraying, and is compatible with various brazing methods including torch, furnace, and induction brazing. Ideal for automotive heat exchangers, HVAC components, and aluminum tubing assemblies, this flux ensures improved flow characteristics, joint integrity, and minimal residue. Post-brazing cleaning is recommended to prevent long-term corrosion, especially in moisture-prone environments.
