In the manufacturing of automotive components such as engines, gearboxes, and thermal management systems, brazing material factories supply corresponding brazing materials. For instance, copper-based brazing fillers can be used for welding certain copper components in engines; aluminum-based brazing fillers can be applied to the brazing of thermal management system components like automotive compressors, microchannel radiators, and valves; and silver-based brazing fillers are suitable for welding high-precision and high-reliability connection parts.
