Am I calling this stuff what it really is?

[Sprocket]

Ok, so im not really new to scrapping, but have just kinda been on the newbie side and want to double check some things.





I dismantle my HDD's for magnets and separate boards and tops. Boards are high grade right? Tops are Stainless no?





These are what people call finger boards, right? these are high grade?



RAM is sold as in lots right? No further sorting?



These are aluminum. I would think that they are considered cast or extruded? Are cast and Extruded the same?

I would assume this is cast aluminum?



Would these be considered Extruded or cast? All are AL heat sinks.




Just new to E-scrap.

Dont have a yard around that takes them unless they take them because they are AL. Will have to find a buyer.

Thanks for your information to follow.
