Silver-copper eutectic brazes have melting temperatures between 1100°F and 1650°F. Aluminum braze, the least common, has a melting temperature of 1050°F to 1140°F. Copper braze, the least expensive, has a melting temperature of 1300°F to 2150°F. (p1)
CuSil is a tradename for an alloy of 72% silver and 28% copper (± 1%) marketed by Morgan Advanced Materials. It is a eutectic alloy primarily used for vacuum brazing . [ 1 ] CuSil should not be confused with the similarly named Cusil-ABA, which has a different composition (Ag – 63.0%, Cu – 35.25%, Ti – 1.75%)
At high temperature applied for long time, the zinc diffuses away from the joint. The resulting joint does not present a mechanical weakness and is corrosion-resistant. The technique is known as diffusion soldering. [15] Fluxless brazing of copper alloys can be done with self-fluxing filler metals.
Readily dissolves silver, gold and to less but still significant extent many other metals, e.g. copper; this is a particular concern for tin-rich alloys with higher melting points and reflow temperatures. Zinc lowers the melting point and is low-cost. However, it is highly susceptible to corrosion and oxidation in air, therefore zinc-containing ...

Tin-silver-copper (Sn-Ag-Cu, also known as SAC), is a lead-free alloy commonly used for electronic solder. It is the main choice for lead-free surface-mount technology (SMT) assembly in the industry, [ 1 ] as it is near eutectic , with adequate thermal fatigue properties, strength, and wettability. [ 2 ]
