Alloy #52 is a 50/50 nickel-iron alloy developed for glass-to-metal seals. The alloy's rate of thermal expansion is virtually constant to a temperature of about 1050 non standard kovar alloy electronic component#176;F (565 non standard kovar alloy electronic component#176;C) and is often used as a pin material in compression seals. Plain carbon steel is the most common non alloy used in hermetic applications. It has the

Hermetic Waveguide and Sight Windowsusing the radiation from a focused, energy-dense, beam of infrared light. This non-contact welding process minimizes thermal and mechanical stresses, and provides an extremely small heat-affected zone, ensuring components or electronic packaging are exposed to the least-hostile welding environment possible.

Standard lead time is 2 weeks. Kovar alloy is a vacuum melted, iron-nickel-cobalt, low expansion alloy whose chemical composition is controlled within narrow limits to assure precise uniform thermal expansion properties. Extensive quality controls are employed in the manufacture of this alloy to ensure uniform physical and mechanical properties
Lead Frames Microelectronic Components Hermetic Typically made of Kovar, lead frames may or may not be plated when finished. They are manufactured with a chemical etching process and are generally attached to glass or ceramic. With our decades of experience in supporting hermetic packaging performance, we are the perfect partner to help you identify the best solution for your application.

Of all the low expansion alloys, Alloy 42 (42% nickel, balance iron) has the thermal expansion coefficient closest to that of alumina, and is often used in glass-metal seals.
kovar glass, kovar glass Suppliers and Manufacturers at Kovar alloy has been used for making hermetic seals with the harder Pyrex glasses and ceramic materials. Every year we have over 8000 tons output including wires, bars, strips, sectional materials, non-standard products and so on.
The four non-copper pins are made from 52 Alloy, a metal used for glass or hermetically sealed assemblies. Pictured sizes range from 0.030 to 0.093 diameter by 0.5 to 0.75 long, but are available in diameters ranging from 0.020 to 0.156, and lengths from 0.200 to over 5.
