No it's not extruded. It is made of folded sheet aluminum.
They go by MLC by me.
Scrap Low Copper Aluminum
Low Copper Aluminum shall consist of clean, uncoated aluminum plate, may include clips or punchings
ISRI grade TABOO may be included in this grade
Scrap Aluminum Extrusions
Aluminum Extrusions shall consist of clean aluminum extrusions including window & door frames
Must be free of iron inserts, screws and plastic, rubber or other foreign materials.
if there not extruded where can i get extruded aluminum?
Some window frames are extruded. Some are sheet. It's just a matter of being able to tell the difference.
Most heat sinks are extruded....also round tubing like AL lawn furniture, crutches and walkers.
I had came across some screen windows that were sheet. Didn't realize it till I had em almost apart though. All the pieces on em and the screen itself were aluminum too so I didn't even need to do a thing to em to get clean price.
i didnt know heat sinks were extruded i got ripped off then do i have to tell the scrap guy that its extruded and not asume he will just give it to me? i mean granted i had them mixed in with some other aluminum i thought it was all the same=( am i to asume that i have to seperate it and tell them its extruded? how much is extruded go for?
They will pay you for the lowest priced metal in the pile unless they have a "mixed metal" price or it's like "irony aluminum". Depends on the yard but you really should know what you're doing when you go there. And there's no better teacher than "experience".
You can generally tell if something is extrusion by looking at it closely. You will notice fine lines running throughout (kinda like the playdough machine you had as a kid that you forced the playdough through). I do not think heat sinks are extrusion. I am currently looking at 3 of them sitting on my desk (I use one as a business card holder). Although I could be wrong because everytime someone brings in a Gaylord box full of them I see some I have never seen before. My yard buys them as MLC...which we are currently paying $0.68 a pound for. On a side note we break our extrusion into 2 groups: 6061 and 6063. 6063 is almost always used for structural purposes.
i see thanks now by lines you mean like the lines you see when you cut wood? or lines like what are on heat sinks?
many yards are not familiar with heat sinks, and many who are will try to pay you cast alu price. profit is one thing any one is allowed to maximise in my book, however preditory/vulture profit is not. if you have a yard that just has to screw some one, and I know yard that do. have a searious talk with the window manager, tell him/her to screw the tweekers, if he absolutly needs to screw someone.
Who mentioned anything about cutting wood? Tell ya what, pull that "dip thingy" out of the hot water heater and look real close for the lines on it. Kinda like that.Quote:

lines and etchings are FLAWS. Most extrusions are smooth. There are so many web sites for extruded AL. If you who have questions would just do a little research you will find plenty of info with pictures that will answer all of your questions. I simply copied that info and took it to my yard.
ah thanks everyone is helpful even the funny ones=)
Yeah I've found that when I took mine in but still got a decent price.Quote:

For extruded shapes, note that if the tee, angle, or square tube shapes have a sharp inside corner (no radius) corner they are 6063.* Heavier I-beams, channels, and angles are typically 6061.* Sheet and plate come in a wide variety of alloys and can't be readily identified visually. My yard is specifically geared for regular scrapers as they are where 90% of my product comes from. As a result, my scale operators have orders to sort customer's loads for higher value items the first few times that a new client comes in or whenever they bring in a material that they have questions about.
Here's a reference that helps some with the aluminum identification game:

Yes.. BohemianLush used the example I use everyday at my yard.. I tell them extruded aluminum is forced through a die.. the same way play-doh is forced through the toy making shapes. Extruded has designs that are a lot of the time impossible to mimic by bending aluminum..
The yard by me only has 3 grades of aluminum: Sheet, Irony, and Cast. When I went three weeks ago, the window frames went in as sheet aluminum @ $0.63/lb .
The window screen frames if you look closely you will see that the aluminum has been bent and molded into shape which makes them sheet. Window frames most of the time will be extruded. If your not used to the look and feel of the two it can be tricky. And if in doubt place items in a seperate bin when going to the yard and see if they can help sort. Just make sure its a slow day and not a whole lot.
The yard by me just changed their aluminum grades. Now they only have mixed al, and al cans. Last time I was there they put my al sheet and al extrusion together, but took the cast al separate. I was really surprised when they put all my carefully separated cast and sheet together this time.
Last time I took some mixed and wanted to ask how they separated it. They had a can crusher set up right beside the scale and with all the racket that thing was making, there wasn't any way one could possibly communicate with the scale operator.
The Fuzzy Pumper Barber Shop. "We'll fix Mommy's hair just so, you can do it with PlayDough!" How do I remember this crap??
My yard is cast, sheet, irony and wheels. No extruded. I need to find another yard.
I took in a bunch of heat sinks last week. They gave me "old sheet" price for them. They weren't cast so they must have been sheet? Grrr
I think it all has to do with the part of the country you are in. My local yard doesn't recognize the lines on aluminum as extruded anymore. Now they go by thickness. If it isn't thick enough, they say it is sheet.
Computer heat shrinks are extruded. Coming out to the die they would look like a bunch of "W's" lined up if you were to look at the them from the end. They are then cross cut to make the little points.
Window frames that are rolled out of sheet will have a seam which is crimped. If you look at one of these frames from the end you can also see how the sheet was rolled to form the shape of the frame then crimped.
Extruded window frames need to have the die cast clips which normally hold the ends together removed or cut off from the ends in order to receive extrusion price. If the clips in the ends are not removed or the window frames still have screws in them we buy them as old sheet. This may be why you didn't receive extrusion price for them because they were not clean or the scale operator didn't think you knew the difference and paid you less trying to make themselves more.
