A GKN PLC unit is commercializing a new powder titanium product for additive manufacturing. GKN Hoeganaes Specialty Metal Powders is offering AncorTi™ Beta 21S, a high-strength, heat-treatable titanium alloy suitable for aerospace parts, medical and surgical instruments, and other applications in chemical processing and marine systems.
GKN Hoeganaes is the materials division of GKN Additive, a business formed in October to concentrate the engineering group’s activities in additive manufacturing. The business includes operations drawn from GKN Aerospace, GKN Driveline, and GKN Powder Metallurgy, and develops and produces AM parts for civilian, military, and business jets and space aircraft, as well as major automotive platforms.
The new material is a “beta titanium alloy,” meaning it incorporates other elements (e.g., molybdenum, vanadium, niobium, among others) and offers improved resistance to oxidation and "creep," with enhanced strength at high temperatures.
AncorTi Beta 21S is available in particle sizes optimized for electron beam melting (EBM) and selective laser melting (SLM) additive manufacturing. It’s among a range of metal powders GKN produces for additive manufacturing, including specialized nickel-based alloys, nickel-titanium powders, as well as titanium powders.
