Cov txiv ntseej yog tsim los ntawm cov hlau tsis muaj hlau, cov hlau tsis muaj steel, tooj liab alloys, aluminium alloys, thiab hlau alloy, thiab lwm yam. Cov ntaub ntawv sib txawv tsim nyog rau qhov chaw ua haujlwm sib txawv thiab cov kev xav tau ntawm kev ua haujlwm.
Hom thiab cov yam ntxwv ntawm cov khoom siv:
Cov pa roj carbon steel: Tus nqi qis thiab lub zog siab, nws yog cov khoom siv feem ntau siv rau cov txiv ntoo zoo tib yam. Nws feem ntau yog kho nrog galvanizing lossis blackening los txhim kho xeb tiv thaiv, haum rau kev lag luam thiab kev tsim kho.
Stainless hlau: zoo heev corrosion kuj thiab zoo nkauj. Cov qib sib xws yog 304 thiab 316. Tsim nyog rau ib puag ncig uas yuav tsum tau ua kom huv huv, xws li cov av noo, sab nraum zoov, lossis cov tshuab ua zaub mov.
Copper alloys (xws li H59 tooj dag): Muaj hluav taws xob zoo thiab thermal conductivity thiab corrosion kuj. Feem ntau siv nyob rau hauv cov khoom siv hluav taws xob, li qub, cov kav dej, thiab kev txhaj tshuaj - cov molded inserts, tshwj xeeb tshaj yog tsim rau cov ntawv thov uas xav tau kev tiv thaiv xeb thiab hluav taws xob conductivity.
Aluminium alloys: Lub teeb yuag thiab corrosion- tiv taus, tab sis muaj zog tsawg. Feem ntau yog siv hauv aerospace, cov khoom siv hnyav, thiab lwm yam uas yuav tsum tau txo qhov hnyav.
Alloy steel: Nws lub zog thiab siab -kub tsis kam yog txhim kho los ntawm kev ntxiv cov khoom xws li chromium thiab molybdenum. Nws feem ntau yog siv los ua lub ntsuas phoo rau siab - lub zog bolts thiab haum rau hnyav - lub luag haujlwm thiab siab - qhov kub thiab txias ua haujlwm.
