2% Ag 7% P 91% Cu |
AWS A5.8 BcuP-6 | 1190°F 643°C |
1450°F 788°C |
For copper or brass. Sluggish flow, used for joints with wider clearance. Recommended joint clearance . 003 - .005” (.076 - .127 mm).designed to broaden melting range of Harris 0, and has proven useful in some specific applications where mechanical properties are less critical. | .050" x 1/8" x 20" (1.27 mm x 6.35 mm x 508 mm) - 28 Stick Tube |
STAY-SILV® 5 |
5% Ag 6% P 89% Cu |
AWS A5.8 BcuP-3 | 1190°F 643°C |
1500°F 816°C |
For copper or brass. Used to bridge gaps where close fit-up cannot be maintained. Recommended joint clearance . 003 - .006” (.076 - .152 mm).well suited where close fit-up cannot be maintained. | .050" x 1/8" x 20" (1.27 mm x 3.18 mm x 508 mm) - 28 Stick Tube |
STAY-SILV® 15 |
15% Ag 5% P 80% Cu |
AWS A5.8 BcuP-5 | 1190°F 643°C |
1475°F 802°C |
For copper or brass. Useful for wide clearances. Recommended joint clearance . 002 - .006” (.076 - .152 mm). excellent for situations in which close fit-up does not exist, and where thermal expansion and service vibration are involved. |
.050" x 1/8" x 20" (1.27 mm x 3.18 mm x 508 mm) - 28 Stick Tube |
STAY-SILV® 35 |
35% Ag 33% Zn 32% Cu |

1350°F 732°C |
Use with ferrous and nonferrous based metals. Moderate temperature and good ductility.Safety-Silv® 35 joints are strong, ductile with brazing temperatures only slightly higher than cadmium-bearing 30 and 35 silver alloys. | 3/32" x 18" (2.38 mm x 457.20 mm) 15 t.o. (467 g) - 1 Tube |
DYNAFLOW® |
6.1% Ag 6% P 87.9% Cu |
-------- | 1190°F 643°C |
1465°F 796°C |
Premium alloy for copper or brass. Recommended joint clearance .003 - .006” (.076 - .152 mm).It has excellent strength and ductility. It can be used as a replacement for 15% silver. Perfect for brazing both tight and loose fitted applications. It is a great choice for HVAC/R technicians. | .050" x 1/8" x 20" (1.27 mm x 3.18 mm x 508 mm) - 28 Stick Tube |
