Yes, it appears to be. The main body appears to be a lightweight alloy. The main structure is metal, NOT plastic. It is covered in sections with a rubber material to give you a better grip. It screws onto the camera body using the screw mount that you would use for a tripod. I have found it to be a very good addition to the D7100. The camera recognizes it and I have had no trouble with the battery or the buttons. It comes with both the EN-EL15 battery tray and a second tray for AA batteries. Some say the fit is not good, I have NOT found that to be true. I find the fit to be good for an add-on grip. It is very firm and sturdy in my opinion. It was well worth the extra money in my opinion. I have large hands and it fits my hands very well giving me the confindence of a firm grip. My wife and daughter have not had any trouble using the camera with this grip. Hope this helps.

I don't know about the inside construction, but the outside seems to be full metal.

I will only say this is high quality steel and aluminum, not cheap material. Beyond that I don't live in a salty air environment and cannot give an informed opinion on the issue sorry

Yes. It's made of all aluminum. I've been using it for 3 month with no issue. Great product.

It's metal--you specifically asked about the engine block, not the pedestal--the model parts are metal.

Pretty sure it is cast aluminum with a powder-coat finish. The color looks different than the picture.

It is NOT aluminum. This thing is HEAVY-DUTY. It lifts my full dresser with no sweat. Glad I choose this one!

No it is cast aluminum with a teflon type coating. Works pretty good, but you have to use low heat or products will stick

Only the ingot mold, is cast aluminum. The housing and plate where the melting pot sit are sheet steel.

No. Solid aluminum, just like the body of the flashlight or the cap which comes on a DS streamlight.

I would say not aluminum because I was rough with mine a couple of times and it started to rust.

Yes it is but it is VERY expensive. I opted when getting more for the 64 oz Swanson Ultra Magnesium Oil for i believe $49. That is definitely Magnesium Chloride and it is pure and 100%. The other stuff seems a rip off comparatively to me for only 8 oz.

It appears to be cast iron, it might be aluminum. Whatever it is made of it is made of sturdy construction.

I am not 100% but close to it, steel. Magnets stick to them so they are not aluminum.

It is aluminum, my ol one was just a rubber grommet with a insert. The insert melted on overheating. This one works the same way!
