Kakaretso ea Sehlahisoa:
Terata ea motsoako oa 4J29, e tsejoang hape e le motsoako oa ho tiisa oa Fe-Ni-Co kapa terata ea mofuta oa Kovar, e sebelisoa haholo lits'ebetsong tse hlokang ho tiisoa ha khalase ho tloha ho tšepe ho ea ho khalase. E na le hoo e ka bang 29% ea nickel le 17% ea cobalt, e leng se e fang katoloso e laoloang ea mocheso e tsamaellanang haufi-ufi le khalase ea borosilicate. Sena se etsa hore e be ntle bakeng sa tšebeliso liphaepheng tsa elektroniki, li-relay tsa vacuum, li-sensor tsa infrared, le likarolo tsa sehlopha sa lifofane.

Sebopeho sa Thepa:

• Nikele (Ni): ~29%

• Cobalt (Kopo): ~17%

• Tšepe (Fe): Tekanyo

• Dielemente tse ding: palo e nyenyane ya Mn, Si, C, jj.

Katoloso ea Thermal (30–300°C):~5.0 x 10⁻⁶ /°C
Botenya:~8.2 g/cm³
Ho hanyetsa:~0.42 μΩ·m
Matla a tšepe:≥ 450 MPa
Ho lelefatsa:≥ 25%

Boholo bo fumanehang:

• Bophara: 0.02 mm – 3.0 mm

• Bolelele: hodima di-spool, di-coil, kapa bolelele ba ho kgaola ha ho hlokahala

• Bokaholimo: E khanyang, e boreleli, ha e na oxidation

• Boemo: E huloa ka hare kapa e batang

Likarolo tsa Bohlokoa:

• Ho tsamaisana hantle ha katoloso ea mocheso le khalase e thata

• E loketse ho kwala ka har'a sekwahelo lits'ebetsong tsa elektroniki le tsa lifofane

• Ho tjheseletsa hantle le ho nepahala ho phahameng

• Matla a makenete a tsitsitseng tlas'a maemo a fapaneng a tikoloho

• Li-diameter tse ikhethileng le likhetho tsa ho paka lia fumaneha

Likopo tse Tloaelehileng:

• Li-relay tsa vacuum le li-relay tse koetsoeng ka khalase

• Sephutheloana sa infrared le disebediswa tsa microwave

• Liphepelo le lihokelo tsa khalase ho tloha ho tšepe

• Li-tube tsa elektroniki le li-sensor tse ka sebelisoang ho laola

• Likarolo tsa elektroniki tse koetsoeng ka thata sefofaneng le ts'ireletsong

Sephutheloana le Thomello:

• E fumaneha ka li-spool tsa polasetiki, li-coil, kapa mekotla e koetsoeng ka vacuum

• Ho paka ho thibela mafome le ho thibela mongobo ka boikhethelo

• Thomello e fumaneha ka sefofane, leoatle, kapa ka potlako

• Nako ea ho tlisa: Matsatsi a 7-15 a mosebetsi ho latela bongata

Ho Sebetsana le ho Boloka:
Boloka tikolohong e omileng, e hloekileng. Qoba ho pepesehela mongobo kapa lik'hemik'hale. Ho ka hlokahala ho e qhaqha hape pele ho e koala ho netefatsa hore e tlamahane hantle le khalase.
