Material Notes:
Annealing Temperature 700-785℃。 Alpha-Beta Alloy
Subcategory: Alpha/Beta Titanium Alloy; Metal; Nonferrous Metal; Titanium Alloy
Key Words: Ti-6-4; UNS R56400; ASTM Grade5 titanium; UNS R56401(ELI), Ti6Al4V, biomaterials, biomedical implants, biocompatibility.
Applications: Blades, discs, rings, airframes, fasteners, components. Vessels, Cases, Hubs, Forgings.
Biocompatibility: Excellent, especially when direct contact with tissue or bone is required. Ti-6Al-4V's poor shear strength makes it undesirable for bone screws or plates. It also has poor surface wear properties and tends to seize when in sliding contact with itself and other metals. Surface treatments such as nitriding and oxidizing can improve the surface wear properties.
General Characteristics: The high strength, low weight ratio and outstanding corrosion resistance inherent to titanium and its alloys has led to a wide and diversified range of successful applications which demand high levels of reliable performance in surgery and medicine as well as in aerospace, automotive, chemical plant, power generation, oil and gas extraction, sports, and other major industries.
In the majority of these and other engineering applications titanium has replaced heavier, less serviceable or less cost-effective materials. Designing with titanium taking all factors into account has resulted in reliable, economic and more durable systems and components, which in many situations have substantially exceeded performance and service life expectations.
Titanium is available in several different grades. Pure titanium is not as strong as the different titanium alloys are.
Special characteristics: Ti6Al4V is the most widely used titanium alloys. It features good machinability and excellent mechanical properties. The Ti6Al4V alloy offers the best all-round performance for a variety of weight reduction applications in aerospace, automotive and marine equipment.
Ti6Al4V also has numerous applications in the medical industry. Biocompatibility of Ti6Al4V is excellent, especially when direct contact with tissue or bone is required.
Applications: Ti6Al4V is typically used for：
--Direct manufacturing of parts and prototypes for racing and aerospace industry
--Biomechanical applications, such as implants and prosthesis
--Marine applications
--Chemical industry
--Gas turbines
