High-Performance Titanium Round Bars: Grades, Uses & Key Properties

Technical Report: AMS 4928 Annealed Ti-6Al-4V Titanium Bar Ø150×1000mm for Aerospace Applications

The AMS 4928 specification covers titanium alloy bars, forgings, and stock for forging, specifically the Ti-6Al-4V grade, which is among the most widely used titanium alloys in aerospace and high-performance engineering applications. The product in focus—a titanium bar with a diameter of 150mm and a length of 1000mm—has been processed in the annealed condition to meet aerospace-grade standards for strength, toughness, and structural stability.

Ti-6Al-4V (Grade 5) alloy consists of approximately 6% aluminum and 4% vanadium, with the remainder being titanium. This alpha-beta alloy offers a unique combination of high strength-to-weight ratio, excellent corrosion resistance, and good weldability. The annealing process further enhances its mechanical uniformity by relieving residual stresses and improving ductility, which is crucial for components subject to dynamic or cyclic loads in flight-critical environments.

Manufactured in accordance with AMS 4928, this titanium bar meets stringent aerospace quality requirements, ensuring high reliability under demanding service conditions. The specified dimensions—150mm diameter and 1000mm length—make it suitable for machining into structural aircraft components, such as landing gear elements, fuselage frames, and engine mounts.

Dimensional accuracy, surface integrity, and microstructural consistency are verified through rigorous inspection protocols including ultrasonic testing and metallographic analysis. Material traceability and certification are provided to support quality assurance and compliance with aerospace procurement standards.

In summary, the AMS 4928 Ti-6Al-4V annealed bar in Ø150×1000mm dimensions is engineered to deliver dependable performance in aerospace applications, combining superior material characteristics with compliance to established industry standards. Its versatility and proven track record make it an optimal choice for aerospace OEMs and Tier-1 suppliers.
