Ti6Al7Nb Titanium Bars

Ti6Al7Nb yog lub siab -lub zog, corrosion-resistant alpha-beta titanium alloy. Nws tau tsim los ua ib qho kev txhim kho biomedically hloov mus rau ntau hom Ti6Al4V alloy, tshwj xeeb tshaj yog rau daim ntawv thov kev phais. Qhov sib txawv tseem ceeb yog kev hloov pauv ntawm qhov muaj feem cuam tshuam nrog Vanadium (V) nrog ntau biocompatible Niobium (Nb).

Lub "6Al7Nb" nyob rau hauv lub npe qhia nws nominal tshuaj muaj pes tsawg leeg: 6% Aluminium (Al);

7% Niobium (Nb); Sib npaug Titanium (Ti).

Ti6Al7Nb titanium tuav yog khoom plig rau cov nram qab no ua ke ntawm cov khoom:

• Biocompatibility zoo heev:Qhov no yog nws qhov zoo tshaj plaws. Niobium yog inert heev thiab tsis yog - tshuaj lom nyob rau hauv tib neeg lub cev, ua rau nws zoo kawg nkaus haum rau ntev - lub sij hawm phais implants. Nws tsis ua rau muaj kev cuam tshuam tsis zoo thiab sib haum nrog lub cev nqaij daim tawv thiab kua dej.
• High Specific Strength:Nws muaj lub zog zoo heev - rau - qhov hnyav piv, piv rau Ti6Al4V. Nws muaj zog npaum li ntau cov hlau tab sis txog 45% sib dua, uas yog qhov tseem ceeb rau kev txo qhov hnyav ntawm cov khoom cog thiab cov khoom siv dav hlau.
• Qhov zoo tshaj plaws Corrosion Resistance:Zoo li feem ntau cov titanium alloys, nws tsim ib tug ruaj khov, adherent, thiab tiv thaiv oxide txheej (feem ntau TiO₂) ntawm nws nto. Cov txheej no ua rau nws tiv taus corrosion hauv ntau qhov chaw, suav nrog cov tshuaj chloride- muaj cov xov xwm (xws li cov kua hauv lub cev thiab dej hiav txwv).
• Zoo Fatigue Resistance:Nws tuaj yeem tiv taus ntau zaus ntawm kev ntxhov siab, uas yog qhov tseem ceeb rau kev cog qoob loo xws li lub duav stems thiab cov pob txha pob txha uas yuav tsum tau thauj khoom tas li.
• Tsawg Modulus ntawm Elasticity:Nws modulus nyob ze rau ntawm tib neeg cov pob txha dua stainless hlau los yog cobalt -chromium alloys. Qhov "modulus matching" no pab txo kev ntxhov siab tiv thaiv, ib qho tshwm sim uas cov cog cog qoob loo ntau dhau, ua rau cov pob txha uas nyob ib sab tsis muaj zog thiab resorb.
• Fabricability zoo:Ti6Al7Nb tuav tuaj yeem ua tshuab, forged, thiab kub- tsim, txawm hais tias lawv xav tau cov txheej txheem tshwj xeeb rau titanium alloys kom tsis txhob ua haujlwm hnyav thiab cov cuab yeej hnav.

Cov khoom ntawm Ti6Al7Nb titanium tuav ua rau lawv zoo tagnrho rau kev thov hauv kev kho mob thiab biomedical sectors.

Hip Joint Prostheses:

Femoral stems thiab taub hau.

Knee Joint Hloov.

Pob txha Screws, Phaj, thiab Nails:

Rau kev raug mob thiab txha caj qaum.

Kev Kho Hniav.

Critical Surgical Instruments.

• ASTM F1295 Cov Lus Qhia:Txuj kev qhia tshwj xeeb rau Wrought Ti-6Al-7Nb Alloy rau kev phais kev phais.
• ISO 5832-11:Implants rau kev phais - Wrought titanium 6-aluminium 7-niobium alloy.

Ti6Al7Nb titanium tuav yog ze rau - alloy engineered tshwj xeeb rau kev phais cov ntawv thov. Los ntawm kev hloov cov tshuaj lom vanadium hauv Ti-6Al-4V nrog niobium, nws muab lub zog tshwj xeeb, txo qis elastic modulus, zoo biocompatibility thiab superior corrosion kuj nyob rau hauv lub cev kua. Nws yog tsuas yog vanadium-dawb titanium bar alloy pom nyob rau hauv ISO 5832-11 thiab ASTM F1295. Nws lub luag haujlwm hauv kev kho mob yog tsim kom zoo thiab tseem ceeb rau niaj hnub orthopedic thiab kho hniav phais.
