3003x.032 instead of 5052x.032 ?

[rmcelroy]

I thought I had a local source of 5052 set up for my 4x10 sheets of Al. That source has fallen through. Another source here in town has 3003x.032-could I use that instead? The 3003 would be backed by wood on all surfaces, maybe that would make up for it being softer.

I have never worked with Al sheet and have no idea how much difference there is in these alloys.

Seems there are a lot of lookers and no suggestors. I am the same as I am building a painted (CPES, Uniflex 255) WeekEnder.
Sorry!

Here you go.

3003: This is the most widely used of all aluminum alloys. It is essentially commercially pure aluminum with the addition of manganese which increases the strength some 20% over the 1100 grade. Thus, it has all the excellent characteristics of 1100 with higher strength. It has excellent corrosion resistance. It has excellent workability and it may be deep drawn or spun, welded or brazed. It is non heat treatable. Applications: cooking utensils. decorative trim, awnings, siding, storage tanks, chemical equipment.

5052: This is the highest strength alloy of the more common non heat-treatable grades. Fatigue strength is higher than most aluminum alloys. In addition, this grade has particularly good resistance to marine atmosphere and salt water corrosion. It has excellent workability. It may be drawn or formed into intricate shapes and its slightly greater strength in the annealed condition minimizes tearing that occurs in 1100 and 3003. Applications: Used in a wide variety of applications from aircraft components to home appliances, marine and transportation industry parts, heavy duty cooking utensils and equipment for bulk processing of food.

Thanks rainjer-I jumped over to aircraft spruce after I posted and did a little reading. It looks like I may be taking a risk using the 3003-but it doesn't look like a outright show stopper in my opinion-set me straight guys if it looks different to you.

I was hoping to find someone here that had hands on with 3003, if no one has then its probably not a good idea.

To change the subject-I did an A/C test yesterday afternoon with the Petcool unit. Even though it wasn't extremly hot at the time because it rained a little, the unit seemed to perform very well. Pics to come-when I picked up the camera the batteries were already dead. I've got to get a better camera.

If you look at my avitar that helicopter is made up of mainly 2024-T3 if that is an option for you if you are looking for strength. There are some components that we use internally on the helicopter that are both 3003 and 5052 but we are required to have all those pieces heat treated. We get all of our aluminum from Airparts Inc. and they can cut to your specified length and ship UPS if it is rolled and its cheaper than Aircraft Spruce.

I ccouldn't tell if that was a heli or gyro copter.

Jason, I looked at the "People at Brantly", are you one of them?

Yep. That pic was several years ago so I look quite a bit younger now.

I'm the one holding that instrument panel.
