Hongfeng has a series of independently developed welding pastes, suitable for air brazing (induction welding, resistance welding, etc.) and vacuum brazing under various conditions, mainly including silver-based welding paste, copper-based welding paste, nickel-based welding paste, aluminum-based welding paste, etc.
The above products are available in 30cc needle cartridges and 1KG cans.
There is less spreading during brazing and good adhesion during high-temperature brazing. Thus, it is applicable to vacuum brazing of stainless steel with higher melting point and brazing in furnace under protective atmosphere, such as brazing of heat exchanger.
It is applicable to copper alloy brazing with lower meting point requirements, such as brazing of VC copper plate in electronic products.
It is used for corrosion and high temperature resistant base metal brazing, such as oil cooler, electric heat tube, etc.
It is applicable to 3-series aluminum brazing, such as automobile oil coolers, home appliance support structures, building materials, etc.
The above products are available in 30cc syringe, 1KG, and 10KG cans.
