HARRIS® 0
Low-cost alloy for many copper-to-copper applications where good fit-up can be maintained and brazing temperature is not critical.

STAY-SILV®  5 AND STAY-SILV®  6
Medium-range alloys, Stay-Silv®  5 is useful primarily where fit-up cannot be tightly controlled. Stay-Silv®  6 is slightly more fluid and can be used where closer tolerances are available. Both alloys are somewhat more ductile than Harris®  0.

STAY-SILV® 15
The industry standard for air conditioning and refrigeration applications. Still widely used, but now often replaced by Dynaflow®  in many HVAC/R applications.
