[Amps] Aluminum alloys for panels?

[David C. Hallam]

Jim,

5052 will work OK.  Go to you local metal salvage yard, i.e., scrap yard and
see what you can find.  I have gotten some pieces of aluminum sheet at
attractive prices.  Don't worry about what alloy it is.

Subject: [Amps] Aluminum alloys for panels?


I need to make two panels and a baseplate for an amp. I could cut down 19"
panels but would like to find a cheaper way. Does anyone know what alloy of
aluminum is used for rack panels? I was thinking it was 6061 but I can't
find it in .125-inch thickness. The hardest I can find in that thickness is
5052. This link compares them for hardness and machinibility:

The baseplate is going to be about 17"x17" and has to hold a 33-lb
transformer and the rest of the amp, so it needs to be fairly stiff. I'd
like the panels to be stiff as well, especially the back, where I'll be
hanging a heavy blower. Is 5052 okay? Thanks.

73,
