For plate and sheet products, AMS 4911 is the primary specification, while AMS 4928 is frequently referenced within aerospace supply chains because it covers the same alloy chemistry and mechanical performance in other product forms.
AMS 4928 vs AMS 4911
AMS 4928 is primarily a specification for Ti-6Al-4V bars, forgings, and wire products. For plate and sheet materials, AMS 4911 is the most commonly referenced specification. However, many aerospace procurement documents and market searches associate Ti-6Al-4V Grade 5 products with AMS 4928 due to the shared alloy chemistry and mechanical properties.

FAQ OF Titanium Grade 5
What is AMS4928 titanium?
AMS 4928 is an aerospace material specification for Ti-6Al-4V (Grade 5) titanium alloy. It primarily covers titanium bars, forgings, and related products used in high-performance aerospace applications.
Is AMS4928 the same as AMS4911?
No. Both standards cover Ti-6Al-4V (Grade 5) titanium alloy, but they apply to different product forms. AMS 4911 sheet, strip, and plate products are common, while AMS 4928 is typically used for bars, forgings, and wire.
What is the yield strength of Ti-6Al-4V?
The typical yield strength of Ti-6Al-4V Grade 5 titanium is approximately 880–950 MPa (128–138 ksi), depending on the product form and heat treatment condition.
What is Grade 5 titanium used for?
Grade 5 titanium is widely used in aerospace components, medical implants, automotive parts, marine equipment, oil and gas systems, and other applications that require high strength, low weight, and excellent corrosion resistance.
Can Ti-6Al-4V be welded?
Yes. Ti-6Al-4V has good weldability and can be welded using processes such as TIG (GTAW), MIG (GMAW), and electron beam welding. Proper shielding with inert gas is required to prevent contamination during welding.
