I'm curious if any of you might have a clue as to the material this item is made from. It very much looks and feels like aluminum however it has a very odd gold tint to it. The attached photo is very representative of what the metal looks like in real life. At first I thought maybe it had some type of zinc chromate treatment. It almost looks like it's very lightly gold anodized. I'm pretty sure it's aluminum but not sure if it's the standard 6061.

I'm also curious what anyone thinks the weight bearing capacity is. For clarification, this is an aircraft jack adapter. The aircraft this is made for sits too low to the ground for a typical aircraft jack to jack it up. The protruding cylinder fits in the wheel axle and the jack goes under the half sphere at the top. I'm looking at creating one of these myself out of 6061 but I'm curious what the weight bearing capacity would be. The part is uniformly thick except for the tapered "nose" at the top where the half sphere is at. Other than this tapered nose, it's about 2 to 2-1/1 thick. Any help or suggestions are appreciated.
