Nickel chromium kupesana neiyo alloy resistohm 40 kurwisa ribbon ni40cr20 yemagetsi heire aya waya waya
Ni90cr20is autenitic nickel-chromium alloy (nicr alloy) yekushandisa pakupisa kusvika kune 1100 ° C (2010 ° F). Iyo Alloy inoonekwa neyakanyanya kuramba uye yakanaka oxidation kuramba. Iyo ine yakanaka ductilility mushure mekushandisa uye yakanakisa allability.
Chaizvoizvo zvikumbiro zve ni40cr20 ihusiku-dzehusiku vapfuti, dzimba dzekutengesa, dzinotakura hutsinye, dzimba dzinorema dziratidzo uye fan heaters. Iyo Alloy inoshandiswawo kune inopisa tambo uye tambo heaters mune defrosting uye de-icing zvinhu, magumbeze emagetsi, zvigaro zvemotokari, basebard hiters uye pasi heaters, resistors.
