Titanium alloys tau lees paub thoob ntiaj teb raws li "Space Metals" thiab "Marine Engineering Metals" vim tias lawv cov kev sib xyaw tshwj xeeb ntawm lub teeb yuag, muaj zog txhua yam, superior corrosion kuj, thiab zoo heev high / low temperature stability.
Niaj hnub no, titanium tau dhau los ua cov khoom siv engineering tsis tseem ceeb hauv kev tsim hluav taws xob hauv aerospace, automotive systems, kho mob cog, offshore engineering, precision zog khoom, thiab additive manufacturing industries.
Ntawm tag nrho cov khoom siv titanium, titanium castings ua lub luag haujlwm tseem ceeb tshwj xeeb vim tias lawv tuaj yeem tsim cov geometries nyuaj, kev sib xyaw ua ke, thiab ze rau -net- cov khoom zoo uas nyuaj los yog kim kom ua tiav los ntawm forging lossis machining.
Txawm li cas los xij, ib qho tseeb tseem tsis hloov pauv hauv ntiaj teb kev lag luam titanium:
Lub sijhawm ntev - kev ntseeg siab ntawm titanium castings yog nyob ntawm ob yam: kev xaiv cov alloy thiab tag nrho - spectrum zoo soj ntsuam.
Rau lub hom phiaj- cov ntawv thov tseem ceeb, txawm tias me me hauv qhov pore, cov ntsiab lus tsis muaj oxygen, lossis microcrack tuaj yeem ua rau qaug zog tsis ua haujlwm, kev tawm tsam corrosion, lossis kev pabcuam ntxov ntxov.
Tias yog vim li cas cov neeg yuav khoom thoob ntiaj teb tsis tsuas yog thov rau titanium castings -
lawv nug txog:
Certified titanium foundry ntau lawm
Traceable raw khoom tswj
100% NDT cov ntaub ntawv tshuaj xyuas
