APAKAH MAKSUD CONSTANTAN dalam CORSICA?
Constantan
Constantan adalah aloi tembaga-nikel yang biasanya terdiri daripada tembaga 55% dan nikel 45%. Juga dikenali sebagai Eureka, Advance dan Feri. Ciri utamanya ialah ketahanannya, yang tetap dalam pelbagai suhu. Aloi lain yang mempunyai koefisien suhu yang rendah juga diketahui, seperti manganin.
Definisi constantan dalam kamus Corsica
Takrif constantan dalam kamus adalah aloi tembaga dan nikel. Ia mempunyai ketahanan tinggi yang tidak banyak berubah dengan suhu dan digunakan dalam perintang dan, dengan tembaga, dalam termokopel.
