AMS4928 one of the most important standards of our titanium products, AMS4928 is a specification that covers a titanium alloy in the form of bars, wire, forgings, flash welded rings, drawn shapes up through 10.000 inches (254.00 mm) inclusive in diameter or least distance between parallel sides and stock of any size for forging or flash welded rings. 
It is widely used in industries that demand high performance and reliability, the specification ensures that these materials meet stringent quality and consistency criteria. It is crucial for applications where exceptional strength, corrosion resistance, and lightweight properties are paramount, making it a cornerstone in aerospace, medical, automotive, and marine engineering.
The Composition of AMS4928
AMS4928 primarily pertains to titanium alloys Ti-6Al-4V, an alloy composed of 90% titanium, 6% aluminum, and 4% vanadium. This combination of elements bestows the material with remarkable strength and durability while maintaining a relatively low density. Aluminum enhances the alloy’s strength and thermal stability, whereas vanadium improves its hardenability and corrosion resistance. The precise balance of these elements ensures that the alloy performs optimally in demanding environments.
