AMS 4956 TB13 titanium wire, corresponding with UNS R58600, is an aerospace-grade beta titanium wire with the nominal composition Ti-4Al-22V. It meets the AMS 4956 specification and is classified as a meta-stable beta titanium alloy. Unlike alpha-beta alloys such as TC4, TB13 maintains a single-phase beta structure at room temperature. This provides: Super-elasticity– Excellent spring-back and shape recovery Cold work-ability– Can be drawn into fine wires without frequent annealing
