* Conductive Glasses

NOTES:
1.  For crystallizing glasses, the contraction coefficient is measured from the recommended sealing temperature to 25 C.
2.  The annealing point and the softening point apply only to the vitreous glasses.
3.  These temperatures can be tolerated for up to ten (10) minutes.
4.  ASTM Metal Designations:
     F-15        29% nickel, 17% cobalt, 53% iron (eg. KOVAR, RODAR, THERLO)
     F-29        Copper clad - 42% nickel, iron (eg. Dumet)
     F-30        Nickel-iron alloys - 42% nickel, 44% nickel, 46% nickel, 49% nickel, 52% nickel
     F-31        42% nickel, 5.5 - 6% chromium, balance iron (eg. Sylvania #4, Carpenter #425)
     F-256      18% chromium, 82% iron (eg. #430 alloy)
     F-257      28% chromium, 72% iron (eg. #446 alloy)
