Kev ua tau zoo, kev xaiv cov khoom siv, thiab kev siv cov hlau hauv qab yog raws li hauv qab no:
Brass Bellows (H80 H -} 60℃-+100 degree): Tsis tshua muaj elasticity, loj hysteresis thiab aftereffect, zoo brazing zog. Haum rau siv los ntsuas cov ntsiab lus hauv cov xov xwm uas tsis yog corrosive thiab cov cuab yeej uas yuav tsum tau ua kom tsawg.
Tin Bronze Bellows (QSn6.5-0.1 × -60℃-+100 degree): Zoo elasticity, lub zog, thiab corrosion kuj; qis hysteresis thiab elastic aftereffect; zoo brazing khoom. Dav siv los ntsuas cov ntsiab lus.
Beryllium Bronze Bellows (QBe2 P -}60℃-+150 degree): Tsis tshua muaj hysteresis thiab elastic aftereffect, siab elastic stability, corrosion resistance, non{5}}magnetic. Feem ntau siv nyob rau hauv high-precision ntsuas ntsuas.
Stainless Hlau Bellows (1Cr18Ni9Ti G -194℃-+400 degree): Siab dabtsi yog khoov qaug zog thiab corrosion kuj; zoo weldability. Nws tuaj yeem siv los ntsuas, sib khi, sib txuas thiab them nyiaj hauv cov xov xwm corrosive.
