No Weapon X yet, but Captain America: Brave New World marks the arrival of adamantium to Earth-616 in a departure from its comic book origins.

That's because Captain America: Brave New World brings adamantium into the fold. The substance shows up in the body of the Celestial that emerged from the Indian Ocean in Eternals. Now, it's the cause of international conflict, as major world powers try to control the world's only known adamantium supply.

Brave New World's is obviously connected to Wolverine and the X-Men, the metal also has dire implications for Wakanda.
