Product Description Product DescriptionIntroductionThe Ti-6Al-7Nb is an Aluminium - Niobium alpha-beta alloy. Its biocompatibility and mechanical properties are superior to those of the Ti-6Al-4V. This alpha-beta titanium alloy came up in 1977 by a team of researchers in Switzerland. Their aim was to create a titanium alloy that would meet the demands of the medical and surgical sectors.CompositionChemical Composition LimitsWeight %AlNbTaFeOCNHTiTitanium 6Al-7nb5.5-6.66.5-7.50.50 max0.25 max0.20 max0.08 max0.05 max0.009 maxBal PropertyMinimum Value (S.I.)Maximum Value (S.I.)Units (S.I.)Minimum Value (Imp.)Maximum Value (Imp.)Units (Imp.)Atomic Volume (average)0.010.011m3/kmol610.237671.261in3/kmolDensity4.514.53Mg/m3281.55282.799lb/ft3Energy Content7501250MJ/kg81254135423kcal/lbBulk Modulus111142GPa16.099220.5953106 psiCompressive Strength10741086MPa155.771157.511ksiDuctility0.10.15 0.10.15NULLElastic Limit895905MPa129.809131.259ksiEndurance Limit559564MPa81.07681.8012ksiFracture Toughness6875MPa.m1/261.883268.2535ksi.in1/2Hardness27002900MPa391.602420.61ksiLoss Coefficient0.0010.002 0.0010.002NULLModulus of Rupture984.5995.5MPa142.79144.385ksiPoisson's Ratio0.350.37 0.350.37NULLShear Modulus3641GPa5.221365.94655106 psiTensile Strength9951005MPa144.313145.763ksiYoung's Modulus100110GPa14.503815.9541106 psiGlass Temperature K °FLatent Heat of Fusion360370kJ/kg154.771159.071BTU/lbMaximum Service Temperature600650K620.33710.33°FMelting Point18001860K2780.332888.33°FMinimum Service Temperature0 K-459.67 °FSpecific Heat540560J/kg.K0.4178830.433361BTU/lb.FThermal Conductivity78W/m.K13.104214.9763BTU.ft/h.ft2.FThermal Expansion89.810-6/K14.417.6410-6/°FBreakdown Potential MV/m V/milDielectric Constant NULLResistivity12615810-8 ohm.m12615810-8 ohm.mEnvironmental Properties Resistance Factors1=Poor 5=ExcellentFlammability5Fresh Water5Organic Solvents5Oxidation at 500C4Sea Water5Strong Acid4Strong Alkalis4UV5Wear3Weak Acid5Weak Alkalis5ProductionTi-6Al-7Nb is produced by powder metallurgy methods. The most common methods are hot pressing, metal injection mouldering and blending and pressing. In the production of Ti-6Al-7Nb, usually a sintering temperature between 900-1400o C is used. Altering the sintering temperature gives the Ti-6Al-7Nb different properties such as different porosity and microstructure. It also gives a different composition between alpha, beta and alpha+beta phases. In the recent years Ti-6Al-7Nb alloys could also be made by different 3D-printer technique such as SLM and EBM.Heat treatmentHeat treatment of titanium is demonstrated to have significant influences on reducing the residual stresses, improving the mechanical properties (i.e. tensile strength or fatigue strength by solution treatment and ageing). Moreover, heat treatment provides an ideal combination of ductility, machinability and structural stability due to the differences in microstructure and cooling rates between α and β phases.[11]The cooling rate have an impact of the morphology . When the cooling rate is reduced for example from air cool to slow cooling, the morphology of the transformed α increases in thickness and length and is contained within fewer, larger α colonies.[12] The α colony size is the most important microstructural properties due to its influences the fatigue properties and deformation mechanics of β processed α+ β alloys. Physical properties of Ti6Al7NbUsual state: solidColour: silver-whiteMelting point: 1720°CMolar volume: 10.64.10-6m3/molDensity: 4,507 g/cm3Electrical conductivity: 2.34.106S/mThermal conductivity: 21.9W/(m?K)Coefficient of thermal expansion: 8.5.10-6/°CApplicationsTi6Al7Nb has a wide range of applications in the medical field, especially in the production of orthopedic implants and dental restorations.Ti6Al7Nb alloy is a new type of medical titanium alloy, similar to the Ti-6Al-4V alloy widely used in clinical practice, and both belong to the α+β type titanium alloy. However, Ti6Al7Nb alloy replaces the toxic vanadium element (V) in Ti-6Al-4V alloy with the non-toxic element niobium (Nb), so it not only avoids the potential harm that the V element may bring, but also retains the high strength characteristics comparable to Ti-6Al-4V alloy. In addition, the Nb element also gives Ti6Al7Nb alloy the advantages of high hardness, corrosion resistance, good ductility, thermal stability and chemical stability.In medical applications, Ti6Al7Nb alloy is mainly used to make orthopedic implants, such as artificial joints. Its excellent mechanical properties and corrosion resistance enable the implant to remain stable in the body for a long time, reduce patient discomfort and improve treatment effects. At the same time, because Ti6Al7Nb alloy has good biocompatibility and can interact harmoniously with living tissues without causing harmful reactions, it is particularly suitable for use inside the human body.In addition to orthopedic implants, Ti6Al7Nb alloy has also received widespread attention in the field of dentistry. It can be used to make dental products such as crowns and dentures to meet patients' dual needs for beauty and function. In addition, with the development of additive manufacturing technologies such as 3D printing, Ti6Al7Nb alloy has also shown great potential in the manufacture of dental implants with complex geometries or composed of reticular structures.In order to improve the performance of Ti6Al7Nb alloy in medical applications, researchers have also studied its surface modification technology. Through oxidation, electrophoretic deposition, ion implantation and other methods, the corrosion resistance, wear resistance and biocompatibility of Ti6Al7Nb alloy can be improved, further broadening its application range in the medical field.
