Sil-Fos- The Original Copper/Phosphorus Alloy
Product Announcement from Lucas Milhaupt Global Brazing Solutions
SIL-FOS® Saves You Time and Money Before Brazing
SIL-FOS® alloys are Copper-based filler metals that are self-fluxing on copper by virtue of their phosphorous content. Because of their self-fluxing nature, you save time and money by eliminating the steps necessary to flux a joint before brazing. However, copper alloys such as brass and bronze should be fluxed with HANDY FLUX™ or Sure Flo Brazing Flux to assure a sound braze joint.
While this filler metal is widely used in the air conditioning and plumbing industries, it is not recommended for ferrous or nickel based materials because the joint will become brittle and may fail. The SIL-FOS® Alloys vary in silver content from 18% to 2% and the percentage of silver and phosphorous does change the melt and flow characteristics of the filler metal.
SIL-FOS® Available in the Following Materials
Our alloys are available in wire and rod, powder and paste, and preformed rings and shapes. Some SIL-FOS® alloys are available in strip as well.
