Curious of a material inside of a Cathode Ray Projector

So, I busted up a CRT monitor. A fairly large one,32 inch flat screen, and inside of the Cathode Ray Projector I found a strange smooth metal, that is magnetic. I was curious to what kind of material this may be. I can't seem to find anything online to tell me what it may be, but I feel like it might be important so I really would like to know. It is very smooth, seems slate like, but it is magnetic. Maybe a compound of metals? Maybe not, I have no idea. Does anyone know what this might be? Oh, and to make it more clear, it is a BLACK satin metal that is very smooth and shatters with a hammer pretty easy.The main reason I'm curious is that I really like to hold on to solid elements (if it is an element and not a compound). So if this is an element I'd love to know.

Be careful, there are a few things inside a CRT which are best avoided!!

Well depending upon the age, there could be lead, barium, phosphors, cadmium, and other toxic materials.
