SIL-FOS® 15

(Formally SILVALOY® 15) For use where close fit-ups cannot be maintained and joint ductility is important. Recommended joint clearance: .002 to .005 (.051 mm to .127 mm). Slow flow. The only phos/copper silver filler metal available in strip or sheet form.

SIL-FOS® 18

A ternary eutectic filler metal for joints where good fit-up can be maintained and low melting point is of prime importance. Clearance: .001 to .003 (.025 mm to .076 mm). Very fast flow.

SIL-FOS® 2M

(Formally SILVALOY® 2M) Has ability to fill moderate gaps in poorly fitted joints. More ductile than FOS-FLO® or SIL-FOS® 2. Intended for use on copper tube headers and similar applications where a sleeve fit is not practical. Recommended joint clearance: .002 to .005 (.051 mm to .127 mm). Slow flow.

SIL-FOS® 5

(Formally SILVALOY® 5) Designed primarily for those applications where close fit-ups cannot be maintained. It has ability to fill gaps and form fillets without adversely affecting joint strength. Recommended joint clearance: .003 to .005 (.076 mm to .127 mm). Slow flow.

SIL-FOS® 6

(Formally SILVALOY® 6F) A very fluid filler metal for close fit-up work. Low melting range makes it ideal where temperature is a factor. Recommended joint clearance: .001 to .003 (.025 mm to .076 mm). Fast flow. Lowest melt and flow in the minimum silver class.
