In an application method of a solid brazing material, while being rotated, the solid brazing material is brought into contact with an aluminum plate material, thereby applying the solid brazing material to the aluminum plate material.

Method of applying solid brazing material, method of producing coated workpiece, application apparatus, and roll-shaped solid brazing material

A brazing material for brazing aluminum or an aluminum alloy includes fluoride-based flux, a solidifying agent, and an organic viscosity reducing agent and is solid at 25° C.

Brazing material, brazing member, heat exchanger, and producing method of brazing member

The present invention provides a brazing material application method that can stably discharge a brazing material containing a fluoride-based flux over a long period of time. The brazing material application method of the present invention includes: a supply step of supplying a liquid brazing material containing a fluoride-based flux to a liquid chamber of a discharge apparatus that is configured to have the liquid chamber having a discharge channel, a plunger disposed in the liquid chamber movably forward and backward, and a drive device for moving the plunger forward and backward and to satisfy a predetermined relationship; and an application step of discharging the brazing material in the liquid chamber from the discharge channel by moving the plunger toward the discharge channel of the liquid chamber by the drive device, and applying the brazing material to a metal member.

Brazing material application method and manufacturing method of metal member for brazing

A brazing material for brazing aluminum or an aluminum alloy includes fluoride-based flux, a solidifying agent, and a coating film uniformity agent, and is solid at 25&#xb0; C.

Brazing material, brazing member, and heat exchanger

A brazing composition contains 1 part by mass or more and 10 parts by mass or less of Zn powder, 1 part by mass or more and 5 parts by mass or less of Si powder, 3 parts by mass or more and 10 parts by mass or less of K&#x2014;Al&#x2014;F flux, 1 part by mass or more and 3 parts by mass or less of (meth)acrylic resin, wherein the mass ratio (Zn/Si) of Zn powder relative to Si powder is 1 or more and 5 or less.
