ASTM F1537 Co-28cr-6mo Alloy Bar
Khoom Description
Lub Co-28Cr-6Mo alloy ib txhij muaj qhov tshwj xeeb hnav tsis kam, corrosion kuj, thiab cov khoom tsis sib nqus-zoo uas tau txais nws lub npe ntawm "King of Medical Metals." Tom qab ntau xyoo ntawm kev ua haujlwm nrog cov khoom siv no, peb pawg neeg muag khoom thiab kev lag luam ntawm Lork Group tau los txog qhov tseeb: thaum nws ua haujlwm raws li "tus qauv kub" rau cov khoom siv hauv kev kho mob pob qij txha, cov teeb meem rau kev nkag mus rau nws cov kub ua hauj lwm thiab machining yog tiag tiag formidable.
Co-28Cr-6Mo (UNS R31537/R31538, ASTM F1537, ISO 5832-12) yog ib qho forged cobalt-chromium-molybdenum alloy tshwj xeeb tsim los rau kev cog qoob loo orthopedic. Nws tsis ua rau muaj kev tsis lees paub tom qab kev phais implantation los yog tsis muaj corrosion, thiab nws tsis cuam tshuam nrog magnetic resonance imaging (MRI) scans. Nws yog qhov tseeb ntawm cov khoom siv no uas yog siv los tsim cov khoom sib txuas ntawm cov pob qij txha thiab lub hauv caug-qhov chaw uas tsis tu ncua rau kev sib txhuam hnub thiab hnub tawm. Txawm hais tias cov hlau tsis zoo tib yam yuav ua tsis tiav vim hnav tom qab ob peb xyoos ntawm kev siv, cov khoom no khaws nws cov haujlwm tag nrho txawm tias tom qab siv sijhawm ntau xyoo ntawm kev puas tsuaj.
Nws cov kev siv ib txwm muaj xws li: pob qij txha femoral taub hau thiab stems, lub hauv caug tibial toj siab, txha nraub qaum sab hauv kho rods, kho hniav cog, thiab cov cuab yeej phais.
Standards thiab Qib Supplied
Tus neeg siv khoom tab tom nrhiav Co-28Cr-6Mo (Chemical Composition Designation) alloy tuav; Lork Group yuav tsum tau lees paub cov qauv thiab qib uas peb muaj peev xwm muab tau.
