Machinie "pure aluminum"

[L Hanft]

An experience or helpful hints for machining this stuff. Have not seen material but was told that it was pure - elemental aluminum. Will be making a deep pocket with islands.

This stuff is soft, soft, soft.

 

It's probably easier to to view these links on commercially available "pure aluminum".

 

1100-O Aluminum

 

or

3105 Aluminum

This is a student project, someone donated a chunk of aluminum and the students want to make an oil pan for their formula race car from this stuff. I suggested 6061,6063 but not to be they like free. I just wondered if I should expect it to be gummy or more free cutting if I blast with coolant.

Gummy, gummy, gummy!!!!

Thanks James, figured it might be. So go slow, go fast.....I'm thinking let it rip and flood, flood flood. BTW, poor me....sob, sob...

If they are planning on making an acutal part for thier SAE formula car, it might be worth getting a drop of 6061 or an alloy more applicable.

 

Also, you can weld 6061 back together when needed....being it's a "student" project and something is bound to go haywire.

 

Oh, I was a student once.
