Nkenke Alloy Iron Nickel waya Invar / Vacodil36/ Feni36 maka iko akara
Invar/ Vacodil36/Feni36Waya maka iko mkpuchi
Nhazi : ọnụọgụ dị ala nke alloy mgbasawanye thermal
Ngwa: A na-eji Invar ebe achọrọ nkwụsi ike dị elu, dị ka ngwa nkenke, clocks, seismic creep gauges, TV shadow-mask frames, valves na moto, na elekere antimagnetic. N'ime nyocha nke ala, mgbe a ga-eme ọkwa ọkwa nke mbụ (nke dị elu), mkpara ndị a na-eme ka ọ dị larịị bụ nke Invar, kama osisi, fiberglass, ma ọ bụ ọla ndị ọzọ. A na-eji invar struts mee ihe na ụfọdụ piston iji gbochie mgbasawanye ọkụ ha n'ime cylinders ha.
