Case material?

Can anyone tell me what material is the engine case made of on a 86 trx250r? I'm assuming it is aluminum.

[norcalduner]

well yeah but its cast aluminum. its brittle as hell.

Thanks for the info. I have a cracked case and was wondering what kind of welder I will need to fix it. Thanks again
