Zita reChigadzirwa:
Waya yeAlloy Inovhara Girazi 4J28 | Waya yeAlloy yeFe-Ni | Zvinhu Zvakapfava zveMagineti

Zvinyorwa:
4J28 (Fe-Ni Alloy, Kovar-rudzi rweKovar-Girazi-Sealing Alloy)

Magadzirirwo:
Inowanikwa mudhayamita dzakasiyana (0.02 mm kusvika 3.0 mm), urefu hunogona kugadziriswa

Mashandisirwo:
Kuvhara girazi kubva kusimbi kuenda kugirazi, machubhu emagetsi, masensa, zvikamu zve vacuum, nezvimwe zvishandiso zvemagetsi zvakanyatsonaka

Kurapa Kwepamusoro:
Nzvimbo yakajeka, isina oxide, yakakweshwa kana kuti inotonhorera

Kurongedza:
Fomu reCoil/Spool, kuputira kwepurasitiki, bhegi rakavharwa ne vacuum kana kurongedza kwakagadzirirwa iwe kana ukakumbira

Tsananguro yeChigadzirwa:

Waya ye4J28 alloy, inozivikanwawo seWaya yeFe-Ni alloy, chinhu chine magineti akapfava uye chinovhara girazi nemagirazi. Nemusanganiswa wacho une simbi uye inenge 28% nickel, inopa girazi reborosilicate rinokura zvakanaka, zvichiita kuti rishandiswe zvakanyanya mukupakata kwemagetsi uye mukuvhara girazi nesimbi.

Waya ye4J28ine hunhu hwakanaka hwekuvharira, kushanda kwemagineti kwakasimba, uye hunhu hwemakanika hwakavimbika. Inoshandiswa zvakanyanya mumachubhu emagetsi, kurongedza mumhepo, dzimba dze semiconductor, uye zvikamu zvemuchadenga nemauto zvinovimbika zvakanyanya.

Zvimiro:

• Kuvhara Girazi neSimbi Kwakanaka Kwazvo: Kuenderana kwakanaka kwekuwedzera kupisa negirazi reborosilicate kune zvisimbiso zvakasimba, zvinopisa

• Zvimiro Zvakanaka zveMagineti: Zvakakodzera kushandiswa kwemagineti kwakapfava uye mhinduro yakasimba yemagineti

• Kunyatsojeka Kwakakwirira: Inowanikwa muhupamhi hwakatsetseka, inodhirowa zvakanyatsonaka kune zvikamu zvemagetsi zvinonzwa

• Kuramba Kuoxidation: Nzvimbo yakajeka, isina oxidation, yakakodzera vacuum uye chisimbiso chakavimbika kwazvo

• Zvinogoneka Kugadziriswa: Zviyero, kurongedza, uye mamiriro epamusoro zvinogona kugadziriswa zvichienderana nezvinodiwa nevatengi

Mashandisirwo:

• Machubhu emagetsi nemidziyo yekutsvaira mhepo

• Magirazi akavharwa kubva kusimbi kuenda kugirazi uye masensa

• Mapakeji eSemiconductor uye e-hermetic

• Zvikamu zvemagetsi zvemuchadenga nemauto

• Zvikamu zve optical uye microwave zvinoda kuenderana kwakanyatsonaka kwekuwedzera kwekupisa
