Question 5

What OEM specifications can Fighter Jet Metals supply material to?

Accepted Answer

Fighter Jet Metals stocks and supplies material to Boeing BMS (BMS 7-43, BMS 7-348, BMS 7-396), Lockheed Martin MMS (MS 342, MS 344), Sikorsky SS (SS 8445, SS 8450, SS 8452), McDonnell Douglas DMS (DMS 1570, DMS 1881, DMS 1888, DMS 2268, DMS 2285), and Pratt & Whitney PWA-S (PWA-S-4928) specifications.

Question 6

What is the difference between annealed AMS 4928 and STA AMS 4965?

Accepted Answer

AMS 4928 covers Ti-6Al-4V in the annealed condition, providing a good balance of strength and ductility. AMS 4965 covers the same alloy in the solution treated and aged (STA) condition, which delivers higher tensile and yield strength. Engineering review is required before substituting one for the other.

Question 7

Is custom processing available from Fighter Jet Metals?

Accepted Answer

Yes. Fighter Jet Metals offers saw cutting, inspection coordination, and test witnessing coordination to support your program requirements. Contact the Fighter Jet Metals team to discuss your specific processing needs.
