in that wiki there is
alot of 'may be this'
'could be this'
but the ball valve is just lazy
The Navy metallurgist had identified the ball as being made of an alloy called stainless steel 431. According to the website of a supplier of this alloy: 431 has been successfully used in a variety of aircraft and general industrial applications. These include fasteners, bolts, valve components and chemical equipment.
Durling-Jones even explained the rattle noted by Hynek: "The rattle comes from trying to patch the sphere... the company drills the spheres and rewelds them before machining them again. Sometimes some of the milling or drilling chips drop inside."
i know for a fact if you catch something top-secret and take a picture of it they will first try and pay you for it and than if you don't take the offer it is going to disappear one way or another

It's not likely any alien technology would be made of a carefully developed (by humans) alloy, stainless steel 431.
5. Because of the steel/nickel shell, most of the lower energy x-rays will be removed before passing into the interior of the sphere, a process called "beam hardening." Only higher energy photons will remain. The higher energy photons have a greater chance of passing through a material without being absorbed. This means that thinner, less dense, lower atomic number objects are less likely to be detected inside the metal container.
6. And so, because the small spheres inside are optically denser than the surrounding, Dr. Harder assumed that they had a much higher anatomic number than iron and nickel, which make up the shell.
7. However, You can see blood vessels inside of the lung on chest x-rays (radiographs), and they appear optically denser than the ribs, especially the ribs on the far side of the detector/film. So what is essentially water (pulmonary vessels) shows up optically denser than calcium (bone). I'm not sure of the physics behind this, but I think this is because the pulmonary blood vessels are surrounded by air and the high contrast between air in the lungs and the adjacent blood vessels makes them visible. You can't see the blood vessels surrounded by other tissues in the chest wall or mediastinum. In other words, the small spheres inside are visible because they are surrounded by air, and can be made of any material that does a decent job of stopping some of the x-rays (probably not wood or plastic).
8. There is only one view of the object. In radiology, we say that "one view is no view." This is because you are taking a 3D object and displaying it on a 2D surface. The spots inside the object may be flat, spheres, or long rods parallel to the x-ray beam. Their location is also not clear. They can be anywhere from the x-ray source housing, surface of the object, interior of the object, far surface, x-ray intensifier screen, x-ray film. The copying process could create them. 9. Objects closer to the film will have sharper margins. Think of your hand making a shadow puppet. As it gets closer to the wall, the edges are sharper. The small lesions inside the object are sharper (especially the round ones), suggesting they are closer to the film.
There is no way to calculate the density of the inner spheres based on the optical density in the image. The optical density (what you see as darker) is a function of the sensitivity of the film, the thickness and type of x-ray intensifier screen used, the number of x-rays hitting the film cassette. The number of x-rays hitting the film cassette is determined by the density of the object, the atomic number of the object and the thickness of the object. We can't even compare it to the density of the shell because it is in a different environment. You can't say it is denser than the shell because it is surrounded by air or gel. See the x-ray image comparing a water density smaller vessel in the yellow circle which is denser (whiter) than the density of two overlapping calcified ribs in the pink circle. I suspect it is about the same density as the shell. It's not wood, not plastic. It could be denser than the shell, but can't tell.
