Is the hub steel or aluminum?

It's a sturdy metal. Don't know what it is but feel comfortable with the durability.

I believe it's aluminum. Steel would be too heavy to lift as easily as this does.

I'm not sure whether aluminum or steel, but it is fairly sturdy. It stood up to very strong winds.

It's a cast piece that seems to be metal, not aluminum. It's very durable and a great tool to have.

I cannot speak scientifically about the materials in the fob, but if I had to guess, the hub is solid brushed stainless steel (it has a bit of heft) with the track where the rings attach being made of chromium steel. Rings are nothing special, spring steel. The build quality is excellent, I've had mine for 5 years with no problems at all. Easily the best keyholder I've owned and perhaps the best made.

It is aluminum. No idea of the guage, but it has withstood two Maine winters and numerous huge wind storms, while loaded with clothes! I really like it and would get another.

The driveshaft is aluminum and the axle shafts (dogbones) are steel.Other than that, a good portion of the suspension is plastic.I haven't had any breakage problems though over a year of ownership and moderate abuse.

This is steel. We have been using it with a very heavy wheelbarrow and it has been working great.

I believe it is non-magnetic and looks like brushed aluminum. The nuts and bolts are magnetic so I expect they are cad plated steel or plain steel

I think it is steel (vs. aluminum) because it is very heavy (and heavy duty).

The stainless steel encompasses the aluminum. It is usually only for heat transfer purposes. .. I purchased this.. still going great

It is metal and lightweight. So I assume it is aluminum. But I'm not certain, sorry.

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

Think it is steel, too heavy to be aluminum - searched it over and nothing on it says. Whatever - it is well done.

Wheels are not rusting, so I presume they are aluminum. So far, we are very pleased with purchase. Much better to haul than wheelbarrow.

Everything I read seems to indicate it is aluminum. I'm assuming that steel would be considerable heavier, and this post only weighs 3.85lbs.
