| Material Summary: | ||||
|
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. |
