AMS 4928 is characterized by the 6AL-4V alloy, and one of the most commonly used alloys. With new and improved revisions over the years, the current version needs to have different reporting and identification processes in the manufacturer’s statement. But what makes AMS 4928 so popular?
The AMS 4928 titanium bar is formed through hot forging which is essential in the formation of the alloy’s mechanical properties. This is coupled with a repetitive process of hot rolling, polishing, machining, extrusion, casting, welding, and spinning the product leading to different AMS 4928 versions depending on the properties. These combined processes make the final product adaptable to the functions it was intended for, in aerospace, automotive, agricultural, and other biomechanical uses, among a few. Due to the nature and tenacity of titanium bars, additional refinement can be added due to the presence of quality bulk material.
With a balanced titanium chemical composition including aluminum composites of between 5-5% -6.75% and Vanadium of between 3.5%-4.5%, the AMS 4928 can be forged to form titanium alloy bars, forging, wire, rings, and drawn shapes. Other properties such as Iron, Oxygen, Nitrogen, Carbon, and Hydrogen have maximum levels ranging from 0.30% to 0.005% depending on the different AMS 4928 specifications. These types of 6AL-4V alloys are structured with varying heat temperatures for the alpha and beta phases to balance differently to produce different uses of the final product.
The tensile properties of the AMS 4928 vary in various section thicknesses, orientation, and organizational engineering preferences. For instance, the new AMS 4928 version has increased coverage from 6′ inch diameter to 10′ inch one, with the least distance between parallel sides. Products that go beyond the 10′ inch diameter require an agreement between the purchaser and the producer.
New and improved versions of the AMS 4928 require various reporting techniques. For instance, products purchase outside different AMS 4928 versions require a statement in the certification highlighting the various exceptions included in the product. There are also significant changes in the surface contamination examination which requires minimum magnification to be 400X.
For purchasers with previous versions of the AMS 4928, a visit back to the manufacturer with the previous certification is needed for verification. This visit authenticates the validity of the certification according to the new product composition and also umps up the magnification levels of surface contamination to match the intended requirements.
The AMS 4928 is manufactured by Alloy Metals Company, a verified full-line distributor with a sensible, secure, and cost-effective process.
