Kovar/UNS K94610

Fa'amatalaga Puupuu:

Kovar (UNS K94610), o se nickel-iron-cobalt alloy e iai le tusa ma le 29% nickel ma le 17% cobalt. O ona uiga fa'alauteleina o le vevela e fetaui lelei ma tioata borosilicate ma alumina ituaiga keramika. O lo'o gaosia i se va'aiga kemisi vavalalata, e maua mai ai mea e mafai ona toe fa'afo'isia lea e matua talafeagai ai mo fa'amaufa'ailoga tioata-i-u'amea i fa'aoga tetele, po'o le fa'atuatuaina e sili ona taua. O mea fa'amaneta o Kovar o lo'o pulea fa'atatau i lona tu'ufa'atasiga ma le fa'aogaina o le vevela.
