5052 aluminum. Suitable for most light and medium duty projects. Can be welded using Forney or similar aluminum mig wire, arc rod, or gas welding specialty rods. This item has no retail packaging. Made in the united states.
Nice piece of aluminium, carefully packed in a double box. But the used clear tape ruined the aluminum and I have to work hard with solvents to get it clean and really nice.
Well packaged and arrived in good condition. I used a metal cutting puzzle sheet to cut aluminum to size to fix a part on my plane. A jigsaw with a metal cutting blade worked well with aluminum this thickness.
Aluminum seems to fit. Due to what I consider to be "mass storage" the item was scratched several times and showed light corrosion. This was my replacement item. I was hoping for a better ending. I'll paint anyway, so the finish won't be a problem. But if you are looking for a nice metallic finish then this product is not for you. Buy something that has been laminated for shipping to give a nice bare metal finish.
