Glass Recommendations for No. 52 Alloy
Glass for Hermetic Seal with No. 52 Nickel-Iron Alloy
|Composition:||52% Nickel, Balance Iron|
|Coefficient of Thermal Expansion:||95 x 10-7 / °C|
|Seal Type||Recommended Elan Glass||Equivalent Glasses|
|Matched||11 or 05||9010
No. 52 alloy is the quintessential go-to alloy for compression sealing pins. It has 52% nickel with iron balance. Its linear expansion up to 525 °C that closely matches that of soft glasses makes it an ideal candidate for Elan 13 and stainless steel housing in a wide range of applications from microwave switches to aerospace electronic seals.
