Automotive Components

Our portfolio covers six categories: copper-based alloy, cadmium-free silver alloy, cadmium-containing silver alloy, lead-free tin solders, brazing paste and matching fluxes. Product forms include rods, wires, rings, sheets, flux and paste. For automotive thermal management systems, cooling circuits, heat exchangers, fluid lines, and sensor components, our silver-based and copper-based brazing materials achieve high-strength, vibration-resistant metallurgical bonds between copper, steel, brass, and dissimilar metals. The joints withstand long-term temperature cycling and the harsh conditions of the engine compartment. Our lead-free tin-based solders are used in automotive electronic control units (ECUs), sensor terminals, and PCB components, fully complying with international RoHS standards. Matching solder paste and flux ensure stable wetting and consistent weld quality in mass production using gas flame brazing, induction brazing, and furnace brazing processes. 

Recommended products: Cadmium-free silver brazing alloy, copper-zinc brazing alloy, copper brazing alloy, lead-free tin-based solders, and brazing paste.

Electronics & PCB Assembly

With extensive expertise in joining technologies, our company provides six categories of advanced soldering and brazing materials: copper-based brazing alloys, silver-based brazing alloys (both cadmium-free and cadmium-containing), lead-free tin-based solders, brazing pastes, and customized flux systems. Our lead-free tin-based solders are a core solution for PCB wave soldering, reflow soldering, manual soldering, and connector terminal assembly. They feature stable melting temperatures, excellent wetting and spreading properties, and minimize thermal damage to heat-sensitive electronic components, ensuring reliable solder joints in communication equipment, consumer electronics, industrial control boards, and automotive electronics. For higher-strength electronic packaging and terminal connections, our cadmium-free silver-based and copper-based alloys provide robust workpiece bonding. Our specially formulated brazing pastes and fluxes are low-residue and suitable for high-density HDI circuit boards and precision electronic components. All products comply with RoHS and international lead-free standards. 

Recommended products: Lead-free tin-based solders, low-silver cadmium-free silver alloy, and electronic-specific fluxes.

Mechanical & Hardware

Leveraging advanced metallurgical expertise, we offer a full spectrum of brazing and soldering materials designed for modern industrial manufacturing. Our product portfolio includes copper-based brazing alloys, silver brazing alloys in both cadmium-free and cadmium-containing formulations, lead-free tin solder alloys, brazing pastes, and dedicated flux solutions. Available in customized forms including rods, wires, rings, sheets, fluxes and pastes, our materials ensure superior bonding performance, reliability, and process efficiency across a broad range of industrial applications. Valves, pipe fittings, tool assemblies, bathroom hardware, and general mechanical assemblies often require connections between copper, brass, carbon steel, and stainless steel. Our copper-based and silver-based brazing materials replace complex mechanical fastening methods, providing high brazed strength, good toughness, and excellent corrosion resistance. Phosphor-copper brazing alloys act as self-fluxing agents for copper-copper joints, while silver-containing brazing rods and rings offer superior flowability and gap-filling properties for joining dissimilar metals. Matching brazing pastes and fluxes effectively remove oxide films and improve wetting, suitable for flame brazing, furnace brazing, and induction brazing processes, ensuring consistent quality in high-volume hardware manufacturing.

Recommended products: Phosphor-copper brazing alloy, copper-zinc brazing alloy, silver-based brazing alloy, and matching flux.
