General Characteristics

Titanium and its alloys are known for their high strength-to-weight ratio and excellent corrosion resistance, making them suitable for diverse applications in industries such as surgery, aerospace, automotive, and more. Titanium often replaces heavier or less durable materials, leading to more reliable and cost-effective systems.

Special Characteristics

Commercially Pure (CP) Titanium is available in four grades, with Grade 1 offering the highest formability and Grade 4 the highest strength. Grade 2 Titanium is noted for its strength and corrosion resistance, making it ideal for medical applications due to its excellent biocompatibility.

Applications

Grade 2 Titanium is used in orthopedic implants, aircraft parts, marine components, condenser tubing, and heat exchangers.

Powder Specification

The Arcam Titanium Grade 2 powder has a particle size of 45 to 100 microns, ensuring safe handling. Refer to the Arcam MSDS for detailed 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: Grade 2 Titanium parts have good machinability with low cutting speeds, high feed rates, and the use of sharp tools and cutting fluids.

Welding: Can be welded using conventional processes, but requires special measures due to chemical reactivity.

Chemical Specification

Grade 2 Titanium meets ASTM F67 standards for surgical implants, with specific limits on elements like carbon, iron, oxygen, nitrogen, and hydrogen.

Mechanical Properties

EBM-produced Grade 2 Titanium has a yield strength of 540 MPa and an ultimate tensile strength of 570 MPa, with elongation at 21% and reduction of area at 55%, surpassing ASTM F67 requirements.

Microstructure

EBM-manufactured Grade 2 Titanium features fine α-grains due to rapid cooling, resulting in a naturally aged condition.
