Invar 36<\\\/h3>\\n

\\n A 36% nickel-iron alloy with the lowest coefficient of thermal expansion of any commercially available metal (approx. 1\\\/10th that of carbon steel) from cryogenic temperatures up to 400\\u00b0F.\\n <\\\/p>\\n

Invar 42<\\\/h3>\\n

\\n A 42% nickel-iron alloy designed with a constant rate of thermal expansion that matches silicon chips, glass, and alumina ceramics. Critical for electronic packaging and hermetic sealing.\\n <\\\/p>\\n

Why Controlled Expansion Matters?<\\\/h3>\\n

\\n Most metals expand significantly when heated. In precision instruments, this expansion causes misalignment. In electronics, the mismatch between a metal chip frame and the silicon chip causes cracking.\\n <\\\/p>\\n

\\n Invar Alloys<\\\/strong> solve this. Invar 36<\\\/strong> essentially does not expand at all near room temperature. Invar 42<\\\/strong> expands at a specific, controlled rate to move exactly in sync with electronic components.\\n <\\\/p>\\n <\\\/div>\\n\\n
