Pfupiso yeChigadzirwa:
Waya ye4J29 alloy, inozivikanwawo seFe-Ni-Co sealing alloy kana kuti waya yerudzi rweKovar, inoshandiswa zvakanyanya mukushandiswa kunoda girazi-ku-metal hermetic sealing. Ine inenge 29% nickel uye 17% cobalt, iyo inoita kuti iwedzere kupisa zvakanaka inoenderana negirazi reborosilicate. Izvi zvinoita kuti ive yakakodzera kushandiswa mumachubhu emagetsi, vacuum relay, infrared sensors, uye zvikamu zveaerospace.

Kuumbwa Kwezvinhu:

• Nickel (Ni): ~29%

• Cobalt (Co): ~17%

• Simbi (Fe): Kuenzana

• Zvimwe zvinhu: zvisaririra zveMn, Si, C, nezvimwewo.

Kuwedzera kwekupisa (30–300°C):~5.0 x 10⁻⁶ /°C
Kuwanda:~8.2 g/cm³
Kuramba:~0.42 μΩ·m
Simba reKusimba:≥ 450 MPa
Kureba:≥ 25%

Saizi Dziripo:

• Dhayamita: 0.02 mm - 3.0 mm

• Kureba: pazvipunu, macoil, kana urefu hwekucheka sezvinodiwa

• Pamusoro: Yakajeka, yakapfava, isina oxidation

• Mamiriro: Yakadhonzwa kana kuti yakatorwa ichitonhora

Zvinhu Zvikuru:

• Kuenderana kwakanaka kwekuwedzera kwekupisa negirazi rakaoma

• Yakanakira kuvharwa kwemhepo mukushandiswa kwemagetsi uye mundege

• Kugona kusundira zvakanaka uye kunyatsorongeka kwepamusoro

• Zvimiro zvemagineti zvakagadzikana pasi pemamiriro akasiyana-siyana ezvakatipoteredza

• Madhayamita akagadzirwa nemaoko uye sarudzo dzekurongedza dziripo

Maitiro Akajairika:

• Zvishandiso zvemagetsi zvinoburitsa mhepo uye zvinoburitsa girazi zvakavharirwa

• Kurongedza michina ye infrared uye microwave

• Zvinobatanidza girazi kubva kusimbi kuenda kugirazi

• Machubhu emagetsi uye masensa emagetsi

• Zvikamu zvemagetsi zvakavharwa nemhepo mundege nekudzivirira

Kurongedza & Kutumira:

• Inopihwa mumapurasitiki, macoil, kana mabhegi akavharwa ne vacuum

• Kurongedza kunodzivirira ngura uye kunodzivirira hunyoro zvinosarudzwa

• Kutumirwa kunowanikwa nendege, gungwa, kana nekukurumidza

• Nguva yekutumira: Mazuva ekushanda manomwe kusvika gumi nemashanu zvichienderana nehuwandu

Kubata uye Kuchengeta:
Chengeta munzvimbo yakaoma uye yakachena. Dzivisa hunyoro kana kusangana nemakemikari. Kubatanidzazve girazi kunogona kudiwa usati wavhara kuti uve nechokwadi chekuti rinobatana zvakanaka negirazi.
