Vala/ Vacodil36 /I-Feni36Ucingo lwengilazi ebopha uphawu
Ukuhlukaniswa: I-coefficient ephansi ye-thermal expnsion alloy
Isicelo:ValaIyasetshenziswa lapho kudingeka khona ukuqina okuphezulu okuyisisekelo, njengezinsimbi zokunemba, amawashi, ama-gauges ama-saissor, ama-television Shadow-mask, ama-valves kumawashi e-antimagnetic. Ekuhlolweni komhlaba, lapho i-oda lokuqala (ukunemba okuphezulu) ukunyusa izinga lentengo kufanele kwenziwe, izinduku ezisetshenziswayo ezisetshenzisiwe zenziwe nge-invar, esikhundleni sezinkuni, noma ezinye izinsimbi. Ama-invar struts asetshenziswa kwamanye ama-pistons ukukhawulela ukwanda kwawo okushisayo ngaphakathi kwamasilinda awo.

Ama-retant ayisisekelo ngokomzimba kanye nezindawo zemishini ze-alloy:
Ubudeqi: γ = 8,1 g / cm3;
Ukumelana nogesi: ρ = 0,78 OHM MM2? / m;
Izinga lokushisa lephuzu le-curie: θs = 230 ° C;
Modulus of elasticity e = 144 KN / MM2;
