Abstract

PURPOSE:The noble metal braze which comprises working every constituting component composed of noble metals to a thin plate or powder and constituting these to sheet-form through bonding such as cladding, thermocontact-bonding, etc. and which is capable of reducing the number of steps and stabilizing quality at the welding. CONSTITUTION:The noble metal braze comprising bonding an Au thin plate 1, Ag thin plate 2, Cd thin plate 3 and Zn thin plate 4 respectively through contact-bonding and keeping the alloy layer between each adjoining thin plate at the minimum thickness range is made. When this braze is used, the thin plate 4 first begins to melt at its melting point. Next, the alloy which has become eutectic composition at the boundary of the thin plate 4 and thin plate 3 melts and the thin plate 4, thin plate 3, thin plate 2 and thin plate 1 subsequently keep melting in this order while alloying. Namely, the directivity where the braze flows has the characteristic that the braze begins to melt from the thin plate direction and therefore this braze may be effectively used for controlling the braze flow characteristic near the brazed part being heated while being passed in the continuous furnace.
