If there was a material which could handle the internal stress, sure. That material probably doesn't exist.

Like a balloon exists at STP despite being internally at higher pressure, but balloons also pop. Tempered glass also exists and significantly higher pressure and likewise explodes. Often metal structures will retain some stress (sometimes quite high) after manufacture.

The amount of energy released at some of those other materials if they had the magical property of staying together... would be terrifying if popped.
