Invar\u00ae \/ Leghe ad espansione controllata<\/h1>\n

\n Una famiglia specializzata di leghe di nichel-ferro progettate per avere un coefficiente di espansione termica (CTE) eccezionalmente basso o controllato. \u00c8 essenziale per le applicazioni di precisione in cui la stabilit\u00e0 dimensionale \u00e8 fondamentale.\n <\/p>\n <\/div>\n\n

Invar 36<\/h3>\n

\n Una lega di nichel-ferro 36% con il pi\u00f9 basso coefficiente di espansione termica di qualsiasi metallo disponibile in commercio (circa 1\/10 di quello dell'acciaio al carbonio) da temperature criogeniche fino a 400\u00b0F.\n <\/p>\n

Invar 42<\/h3>\n

\n Una lega di nichel-ferro 42% progettata con un tasso di espansione termica costante che si adatta ai chip di silicio, al vetro e alla ceramica di allumina. \u00c8 fondamentale per l'imballaggio elettronico e la sigillatura ermetica.\n <\/p>\n

Perch\u00e9 l'espansione controllata \u00e8 importante?<\/h3>\n

\n La maggior parte dei metalli si espande notevolmente quando viene riscaldata. Negli strumenti di precisione, questa espansione causa un disallineamento. Nell'elettronica, la mancata corrispondenza tra il telaio di un chip metallico e il chip di silicio provoca incrinature.\n <\/p>\n

\n Leghe Invar<\/strong> risolvere questo problema. Invar 36<\/a><\/strong> in sostanza non si espande affatto a temperatura ambiente. Invar 42<\/a><\/strong> si espande a una velocit\u00e0 specifica e controllata per muoversi esattamente in sincronia con i componenti elettronici.\n <\/p>\n <\/div>\n\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
