Carbonadium was a resilient, radioactive metal that was vastly stronger than steel, but more malleable and cheaper than Adamantium. Due to its malleability, carbonadium was less durable than True Adamantium, but still nearly indestructible. The metal was developed in the USSR.
Omega Red had carbonadium coils through which he could transmit his ability to drain life energies. Carbonadium was highly radioactive and objects composed of it had proven to slow accelerated healing factors such as Wolverine's. The only device that could stop those radiations, was the Carbonadium Synthesizer, which had been hidden on the deceased body of a double-agent who died when Team X stole it and escaped from Omega Red during their last mission. 
More recently, the carbonadium synthesizer was retrieved by Dracula who tasked Omega Red to infiltrate Krakoa and lure Wolverine to one of Dracula's hideouts in Paris in order to allow Dracula's soldiers to steal his blood. Once done, Wolverine's blood was then transferred to Dracula, allowing him to now survive when exposed to daylight. His mission completed, Omega Red was given the Carbonadium Synthesizer although Dracula warned him that there was a detonator hidden inside of it as he still had use of him.
