I have stripped a bunch of Mac G5s, as well as some G4s.

I would sincerely appreciate if someone could assist in identifying what grades/type of aluminum are shown in the pics I have uploaded.

I also have about 5-10 pounds of Ceramic Monolithic Capacitors (pic taken from your website from another post has also been uploaded for reference). Is there any avenue for selling these?

The moulded heat spreaders are going to be 3260. You'll probably get clean aluminium radiator at a yard.

Hard drives shells, as long as you removed ALL the other materials such as brass pegs and gold connectors and the motor (turn it over and use a number 2 punch and hammer.). You may need to still pry the copper ring if the motor splits. will go as clean spun aluminium
The case for most G4 and G5 towers are manganese or manganese /al alloy. If alloy, goes the same rate as al car rims.

CMC/MCCs you'll need to track down a specific buyer. Google is your friend. Also try asking local jewelry and coin shops that buy gold. Some may be interested.

scratch the base of that heatsink with a file...sometimes they are copper with a silver colored coating

Good call, though i haven't found copper radiators in G series it's worth looking anyway.

Thanks to all that provided replies.

Just a quick follow up. He's got a fair point on spreaders.
The 'genius' guide (for store employees and authorized repair) states that its 3260 specifically but any after market spreader In an apple will probably be copper with a nickel plating. alot of early Intel macs had a nearly identical copper unit available 3rd party to help cooling monster heat of core chips in the mang shells.
(The got well over 90° and I've heard of chips frying at 150°+؛ ouch!)
