Core Advantages of Flame Brazing with XINRUI
Superior joints through material science, automation-ready product forms and full industrial-chain support
Join Dissimilar Metals with Confidence
Flame brazing creates strong, leak-tight bonds between copper, brass, steel and aluminum — joints that brazing often cannot achieve. XINRUI filler metals and fluxes are formulated for reliable wetting and flow across dissimilar-metal assemblies.
Automation-Ready Product Forms
From flux-cored wires and rings to pastes and dispensable alloys, XINRUI product forms feed directly into manual torches, rotary tables and robotic brazing lines — raising production speed and consistency for every customer.
Lower Heat, Less Distortion
Brazing temperatures are far lower than brazing, so even thin-walled, complex aluminum heat exchangers stay flat and dimensionally stable — protecting precision components and reducing rework.
One-Stop Brazing Product Range
From automated brazing equipment to filler metals, fluxes and torch-side tools — everything your flame brazing process needs, from one supplier.
Al-Al & Cu-Cu Brazing Material
Aluminum-silicon filler metals, aluminum and copper-aluminum flux-cored wires, rings and pastes for aluminum-to-aluminum and copper-to-aluminum joining.
Aluminum Flux
Halide and fluoroaluminate aluminum brazing fluxes - powders, pastes and premixes engineered for clean, oxide-free aluminum joints.
Brazing Equipment
Automated flame brazing machines for mass production - stationary, rotary, conveyor, single/double-station, G/C commercial, robot and dedicated continuous lines for all-aluminum heat exchangers.
Brazing Tool
Complete torch-side equipment: flux vaporizers and generators, FLOTRON, digital wire feeders, flashback arrestors, pressure reducers, precision flow controllers, igniters, nozzles and hoses.
Silver-Copper Brazing Material
Silver-based and copper-based filler metals, flux-coated brazing rings and copper-silver alloy pastes for reliable joining of copper, brass and steel.
