General Characteristics
Titanium and its alloys, such as Ti6Al4V, are known for their high strength-to-weight ratio and excellent corrosion resistance. These properties make them suitable for various industries, including medical, aerospace, automotive, and more. Titanium often replaces heavier and less durable materials, leading to more reliable and cost-effective systems.

Special Characteristics of Ti6Al4V
Ti6Al4V is the most commonly used titanium alloy due to its good machinability and mechanical properties. It is ideal for weight reduction applications in aerospace, automotive, and marine industries. It is also biocompatible, making it suitable for medical implants and prostheses.

Applications
Ti6Al4V is used in direct manufacturing for racing and aerospace parts, biomechanical applications, marine applications, the chemical industry, and gas turbines.

Powder Specification
The Arcam Ti6Al4V powder has a particle size of 45 to 100 microns, ensuring safe handling. Refer to the Material Safety Data Sheet (MSDS) for detailed handling and safety information.

Post Processing
Heat Treatment: Hot Isostatic Pressing (HIP) is recommended for fatigue-loaded components with parameters of 920°C, 100 MPa, and 120 minutes.
Machining: Ti6Al4V parts have good machinability with low cutting speeds, high feed rates, ample cutting fluid, sharp tools, and a rigid setup.
Welding: Ti6Al4V can be welded using various processes, but special measures are needed due to its chemical reactivity.

Chemical Specification
The chemical composition of Ti6Al4V includes Aluminum (5.5-6.75%), Vanadium (3.5-4.5%), Carbon (<0.1%), Iron (<0.3%), Oxygen (<0.2%), Nitrogen (<0.05%), Hydrogen (<0.015%), with Titanium as the balance.

Mechanical Properties
Ti6Al4V exhibits a yield strength of 950 MPa, ultimate tensile strength of 1020 MPa, elongation of 14%, and a reduction of area of 40%. It has a fatigue strength of over 10,000,000 cycles at 600 MPa and a Rockwell Hardness of 33 HRC.

Microstructure
EBM-manufactured Ti6Al4V parts have a superior microstructure compared to cast materials, with a lamellar α-phase and larger β-grains. The rapid cooling in the EBM process results in a higher density and finer grain structure.

Conclusion
Arcam's EBM technology provides a method for manufacturing metal parts with excellent geometric freedom and material properties, suitable for a wide range of applications.
