K93600 Invar36 Ribbon Precision Expansion Alloy Flat Silig
(Magaca guud: Invar, FeNi36, Invar Standard, Vacodil36)
4J36 (Invar), sidoo kale loo yaqaano guud ahaan FeNi36 (64FeNi gudaha Maraykanka), waa daawaha nikkel-birta oo caan ku ah iskudarkeeda hoose ee ballaarinta kulaylka (CTE ama α).
4J36 (Invar) waxaa loo isticmaalaa halka loo baahan yahay xasilooni cabbir sare, sida qalabyada saxda ah, saacadaha, cabbiraadaha seismic ee gurguurta, fareemada hadh-maskarka telefishinka, matoorada matoorada, iyo saacadaha antimagnetic. Sahanka dhulka, marka heerka kowaad (sax-sare) la samaynayo heerka sareynta, shaqaalaha Heerka (usha heerka) ee la isticmaalo waxay ka samaysan yihiin Invar, halkii laga samayn lahaa alwaax, fiberglass, ama biro kale. Invar struts ayaa loo adeegsaday qaar ka mid ah pistons si loo xaddido fidinta kulaylka ee gudaha dhululubadahooda.
4J36 waxay isticmaashaa alxanka oxyacetylene, alxanka korantada, alxanka iyo hababka kale ee alxanka. Maaddaama isku-dhafka balaadhinta iyo ka kooban kiimikada ee daawaha ay la xiriirto waa in laga fogaadaa sababtoo ah alxanka ayaa keenaya isbeddel ku yimaada halabuurka daawaha, waxaa la doorbidaa in la isticmaalo biraha alxanka alxanka Argon arc oo doorbidaya ka kooban 0.5% ilaa 1.5% titanium, si yaree porosity alxanka iyo dildilaaca.
