FeNi Nickel Iron Alloy Precision 0.5mm Invar 36 Waya Yechisimbiso Chaizvo Chiridzwa
FeNi Nickel Iron alloy chaiyo 0.5mmInvar 36 WireYeChisimbiso Chakarurama Chekushandisa
INVAR 36iri nickel-iron, yakaderera kuwedzera alloy ine 36% nickel.Iyo inochengetedza inenge yakadzikama Dimensions Pamusoro pehuwandu hwemazuva ose ekushisa kwemhepo, uye ine yakaderera coefficient yekuwedzera kubva kune cryogenic tembiricha kusvika kune 500 ° F. Iyo alloy inochengetedzawo simba rakanaka uye kusimba pakupisa kwe cryogenic.
INVAR 36inogona kupisa uye kutonhora yakaumbwa uye yakagadzirwa uchishandisa maitiro akafanana ne
austenitic simbi isina tsvina.INVAR 36 inokwenenzverwa uchishandisa Filler Metal CF36 inova
inowanikwa muwaya isina chinhu kune ese ari maviri GTAW uye GMAW maitiro.
