Solder Flush Gold Sheet - Umicore Precious Metals
Manufacturers can use this unique product to solder assemblies without manually applying solder to the parts. This results in considerable time savings and uniform soldering. Solder flush sheet is available as a combined 88% substrate/12% solder flat product. The solder cladding is continuous across the gold base and contains the same proportional amount of gold as the base, therefore not changing the final karat quality. The solder is cadmium free. Available dimensions Width: up to 2” *Other dimensions available upon request. Firing information Solder flush sheet items can be bonded using either a furnace or a torch. In both cases a reducing atmosphere and clean surfaces are recommended. When using a furnace, final parameters will be based on furnace specifics (thermal profile), the mass of the pieces loaded, as well as the temperature of the pieces when loaded. To get the solder to run, parameters must be set to allow sufficient time at temperatures above the solder liquidus. To avoid excessive grain growth in the base, this same set of parameters should involve temperatures well below the base solidus.
