1. Muaj pes tsawg leeg
Kovar alloy: Feem ntau muaj txog 29% npib tsib xee, 17% cobalt thiab 54% hlau.
Invar alloy: Feem ntau muaj txog 36% npib tsib xee thiab 64% hlau25.
2. Kev Ua Haujlwm
Thermal nthuav tawm coefficiention: Lub thermal nthuav kev coefficient ntawm Kovar Alloy yog 4.57x10⁻⁶m / MK, thiab lub thermal expar kev cuam tshuam ntawm kev cuam tshuam tsuas yog 1.2x10⁻⁶m / MK4.
Melting taw tes thiab ntom: lub ntsiab lus melting ntawm Kovar Alloy yog 1430 Qib thiab qhov ceev yog 8800KG / ML; Lub ntsiab lus melting ntawm cov khoom sib txuas yog txog 1425 degree thiab qhov ceev yog 8100kg / ml4.
Lub zog sib nqus: Kovar Alloy muaj cov lus teb sib nqus, tsis sib thooj alloy yog cov hlau nplaum me me, nrog cov hlau nplaum qis thiab hysteresis.
3. Ua nyuaj
Kovar alloy: kev ua haujlwm zoo ua tau zoo, tuaj yeem tsim tau yooj yim los ntawm kev txias dov, kub dov, nias thiab Forging.
Invar alloy: vim nws lub siab tawv thiab tawv, nws yog qhov nyuaj rau kev ua.
4. Daim ntawv thov teb
Kovar alloy: Nrog rau cov cua sov nthuav tawm cov coefficient zoo li cov khoom siv hluav taws xob zoo ib yam, cov khoom siv hluav taws xob, cov tshuab hluav taws xob, cov tshuab raj, cov titters thiab lwm thaj teb.
Invar Alloy: Nrog nws cov khoom lag luam tsawg kawg ntawm cov coefficient, xws li cov khoom siv kho tshiab, lub siab-precision seem hauv Aerospace, thiab lwm yam.
