Tungsten carbide Seats thiab Valves yog siv rau hauv ntau yam roj thiab roj foob, oilfield li qub, Coal chemical kev lag luam. Nyob rau lub sijhawm ua haujlwm ntev thiab hnyav, tungsten carbide valve yog qhov kev xaiv zoo tshaj plaws. Nyob rau tib lub sijhawm, tungsten carbide valve thiab lub rooj zaum muaj qhov zoo hauv qab no: tsis tshua muaj suab nrov thiab siab hnav-tiv taus; siab hardness, siab compressive zog; Zoo tshuaj stability thiab tsis tshua muaj kev cuam tshuam toughness; tsawg expansion coefficient; thermal conduction thiab hluav taws xob conduction.
