Ko te K93600 Invar36 Riipene Whakawhanui Waea Papatahi
(Ingoa Nui: Invar, FeNi36, Invar Standard, Vacodil36)
4J36 (Invar), e mohiotia katoatia ana ko FeNi36 (64FeNi i te US), he koranu nika-rino rongonui mo tona whakarea iti o te roha wera (CTE, α ranei).
Ka whakamahia te 4J36 (Invar) ki nga waahi e hiahiatia ana kia mau tonu te rahi, penei i nga taputapu totika, nga karaka, nga inenga ngokingoki ruru, nga papa whakaata-a-whakaata, nga maru i roto i nga motuka, me nga mataaratanga antimagnetic. I roto i te ruri whenua, i te wa e mahia ai te taumata o te taumata tuatahi (te tino tika), ko nga kaimahi Taumata (te rakau taumata) he mea hanga ki te Invar, hei utu mo te rakau, te muka karaihe, me etahi atu konganuku. I whakamahia nga struts invar i etahi piston hei whakawhāiti i te roha wera i roto i o ratou puoto.
4J36 whakamahi oxyacetylene fehokotaki'anga, fehokotaki'anga pewa hiko, fehokotaki'anga me ētahi atu tikanga fehokotaki'anga. I te mea ko te whakarea o te roha me te hanganga matū o te koranu e hono ana me karohia na te mea ka puta he huringa i roto i te hanganga koranu, he pai ake te whakamahi i nga konganuku whakakikorua ki te 0.5% ki te 1.5% o te titanium. whakaiti i te porosity weld me te kapiti.
