Iridium Hlau thiab Qws Description
Iridium yog lub npe hu rau nws hardness, brittleness, thiab siab melting point. Iridium qib siab nruj thiab tsis kam ua rau deformation ua rau nws nyuaj rau tshuab, tsim, lossis ua haujlwm. Txawm li cas los xij, nws pom ntau daim ntawv thov uas lub zog siv tshuab yog qhov tseem ceeb hauv qee qhov kev mob hnyav heev.
Iridium hlau yog feem ntau corrosion-resistant hlau. Nws feem ntau yog siv rau kev siv hluav taws xob xws li filaments thiab cua sov.
Iridium pas nrig yog siv los ua cov khoom siv rau kev thov heev hauv ib puag ncig corrosive heev. Txawm li cas los xij, machining iridium yog qhov nyuaj heev vim nws qhov tawv tawv. Cov kab loj dua iridium rods yog siv los ua cov ntsaws ntsaws.
Dhau li ntawm ntshiab iridium hlau, SSC kuj muab iridium-rhodium alloy hlau (Ir/Rh10) qhov loj ntawm 0.2 mus rau 0.7 hli thiab platinum-iridium alloy hlau (Pt/ Ir10, Pt/Ir20) qhov loj ntawm 0.045 txog 6.0 mm.
