CI- 50150 15. 5 16. 5 18 - BAg- 1a 625 635 9. 5widely accepted for its low soldering temperature & good flow.

CI- 45145 15 16 24 - BAg- 1 605 620 9. 4essentially equal to CI- 501, but with 5% less silver.

CI- 42142 17 17 24 - 620 650 9. 542% silver with melting range 620- 650? C.

CI- 40140 17 17 26 - 620 650 9. 3melting range between 620- 650? C, but just need 40% silver.

CI- 35135 26 21 18 - BAg- 2 605 700 9. 2slightly higher soldering temperature and rapid heating.

CI- 30130 27 23 20 - BAg- 2a 610 710 9. 2an economic product.

CI- 25125 35 27 13 - BAg- 27 620 745 8. 8with higher content of zinc & cadmium. need more

attention during the soldering.

CI- 20120 40 25 15 - 605 765 8. 8good fluidity and is suitable for color match with brass.

CI- 500950 15. 5 15. 5 16 3BAg- 3 630 690 9. 4good corrosion resistance in marine environment & caustic

media. With nickel, largest use is to braze carbide tool.
