产品型号：

Product Features

Titanium-tantalum alloy powder is a new type of functional material with titanium (Ti) as the matrix and tantalum (Ta) as the main alloying element. The typical components are Ti-20TA and Ti-30Ta (by mass fraction), and its properties can be regulated by adding elements such as niobium (Nb), zirconium (Zr), and oxygen (O). It features high sphericity and excellent fluidity, controllable particle size, high purity and low oxygen content, high melting point and high-temperature stability, high strength and good plasticity, corrosion resistance and biocompatibility, low density and high specific strength, and other superior properties. It is mainly used in 3D printing additive manufacturing, powder metallurgy, hot isostatic pressing, etc., and can be applied in fields such as aerospace, energy and nuclear industry, electronics and advanced manufacturing, and biomedicine.

Product details

Titanium-tantalum alloy

I.Characteristics

Low density and high specific strength: Density 6.5-10.5 g/cm³ (much lower than pure tantalum 16.6 g/cm³), tensile strength 800-1200 MPa, elongation 15%-25%, combining the light weight and high strength of titanium alloys with the high-temperature resistance of tantalum.

Outstanding corrosion resistance: The addition of tantalum enables the alloy to perform exceptionally well in extreme corrosive environments such as aqua regia, concentrated nitric acid, and high-temperature hydrochloric acid (>150℃), with a corrosion rate of ≤ 0.01mm/year, far exceeding that of pure titanium and Ti-6Al-4V alloys.

Excellent biocompatibility: The naturally formed TiO₂ -TA ₂O₅ composite oxide film on the surface (with a thickness of 5-10 nm) has extremely low cytotoxicity, a hemolysis rate of < 0.1%, and better bone binding ability than pure titanium, meeting the ISO 10993 biosafety standard.

Wide temperature range adaptability: The operating temperature range is from -253 ℃ (in liquid hydrogen environment) to 800℃. There is no brittle transformation at low temperatures, and the high-temperature oxidation resistance is three times that of pure titanium (the oxidation weight gain at 700℃ is ≤5 mg/cm²).

II.Physical Properties

Sphericity and fluidity: The sphericity of the gas atomized powder is ≥95%, the proportion of satellite spheres is < 3%, and the Hall flow rate is ≤12 s/50g. It is suitable for additive manufacturing technologies such as laser selective melting (SLM) and electron beam melting (EBM).

Particle size distribution: Common particle size ranges are 15-53μm (additive manufacturing) and 50-150μm (powder metallurgy). The particle size uniformity index (span factor) is ≤1.5. The bulk density is 3.5-5.0 g/cm³, and the tapped density is 5.5-7.0 g/cm³.

Purity control: Oxygen content ≤1000 ppm (medical grade) /2000 ppm (industrial grade), nitrogen content ≤100 ppm, carbon content ≤50 ppm, total amount of impurity elements (Fe, Ni, W) < 0.1%.

III.Application Fields

1.Additive manufacturing (3D printing) : It is used to manufacture complex-structured metal parts, such as aerospace components, industrial molds and consumer goods.

2.Chemical Engineering and Marine Engineering: It is used for manufacturing corrosion-resistant equipment and catalyst carriers.

3.Electronic Information and Energy: It is used in the manufacture of current collectors for lithium-ion batteries and fuel cells.
