TC4 ELI Powder

TC4 ELI powder is a titanium alloy known for its exceptional mechanical properties and biocompatibility. It is a variant of Ti-6Al-4V alloy, specifically developed for critical applications in industries such as aerospace, medical, automotive, and sports equipment manufacturing. TC4 ELI powder exhibits enhanced purity and reduced interstitial elements, making it highly desirable for various advanced applications.

TC4 ELI powder, also known as Titanium 6Aluminum 4Vanadium ELI powder, is an advanced titanium alloy powder used in various high-performance applications. This guide provides a comprehensive overview of TC4 ELI powder, its properties, applications, suppliers, grades, and comparisons to other titanium powders.

Overview of TC4 ELI Powder

TC4 ELI powder is a high-purity extra low interstitial (ELI) variant of TC4 titanium alloy containing 6% aluminum, 4% vanadium, and low amounts of iron and oxygen.

Compared to other titanium alloys, TC4 ELI offers an excellent combination of high strength, low weight, outstanding corrosion resistance, and biocompatibility. The ELI grade ensures maximum ductility and toughness.

TC4 ELI is suitable for additive manufacturing, metal injection molding, and other powder metallurgy applications. Its fine powders enable complex geometries and thin walls in 3D printed or sintered parts.

Key properties and characteristics of TC4 ELI powder:

TC4 ELI Powder Properties

Property Description
Composition 6% Al, 4% V, 0.08% max Fe, 0.13% max O
Density 4.43 g/cc
Melting Point 1604°C
Strength 895-930 MPa ultimate tensile strength
Ductility 10-15% elongation
Fatigue Strength 500-550 MPa
Young’s Modulus 110 GPa
Thermal Conductivity 6.7 W/m-K
Electrical Resistivity 178 μΩ-cm

TC4 ELI provides an optimal balance of high strength-to-weight ratio, fracture toughness, fatigue resistance, and corrosion resistance. The high aluminum and vanadium content contributes to achieving high strength through solid solution strengthening and precipitation hardening heat treatments.

The low interstitial levels ensure improved ductility and fracture toughness compared to standard TC4 grade. Oxygen is limited to 0.13% max to avoid embrittlement. Iron content is also restricted.

Overall, the properties of TC4 ELI make it suitable for critical applications across aviation, space, defense, motorsports, medicine, oil and gas, and more.

Finer particle size distributions from 15-45 microns are preferred for printing complex geometries and achieving smooth surface finishes. Larger sizes over 100 microns allow faster build rates.

Spherical powders improve flowability, packing density, and sintering behavior. Angular and blended powders offer better mechanical adhesion between particles.

Apparent and tap density determine the quantity of powder required to fill a given volume. Flow rates indicate ease of dispensing during printing or injection molding.

Chemical analysis confirms that elemental composition meets grade specifications. Lot numbers provide traceability for quality control. Appropriate packaging maintains powder integrity during handling and storage.

Grades of TC4 ELI Powder

TC4 ELI powder is produced in different grades by varying the post-processing method after gas atomization. This affects the microstructure and mechanical properties.

The main grades include:

TC4 ELI Powder Grades

Grade Description
As-atomized No post-processing after gas atomization
Annealed Heat treated to relieve residual stresses
Hot isostatic pressed Consolidated at high temperature and pressure
Plasma sintered Rapidly sintered using plasma discharge
ISO-S Spherical powder made by gas atomization

As-atomized grade contains residual stresses from the rapid solidification. Annealing eliminates these stresses and makes the powder easier to work with during printing or molding.

Hipping and plasma sintering increase the density and improve the microstructure and mechanical properties of the final parts.

Spherical grade (ISO-S) offers better flowability and packing density for high quality 3D printing.

The appropriate TC4 ELI powder grade is chosen based on the specific additive manufacturing or powder metallurgy process being used.
