Are these aluminum or steel?

They're aluminum and come with one extra screw if you over tighten and break one. I have tall and medium rings I use on an ar-15 no problems at all.

These are not steel because a magnet will not attract to them but a magnet will attract to the screws.

I would guess stainless. Definitely not plastic, and too heavy for aluminum.

I'm not sure if it's aluminum or steel.. I can tell you that they're heavy, though. My problem is that the coating stained and peeled/scratched within a few days of use...

No idea what type of steel. Worked just fine for replacement springs on utility trailer. Fulfilled my needs perfectly.

These are stainless steel. Originally I purchased aluminum and had to discard them.

They are steel, got them for my wife's desk top and grandkids play with them with no problems.

I am not totally sure, but if I had to make an educated guess, I would say they are an aluminum alloy.They are light weight and don't seem to rust, even where they are scratched. Hope this helps.

I don't think they are steel--they are lightweight. No rust. We've had the set for two years and they still look new.

They are steel but look nice. I was just looking at them today and I have chrome tips on my tail pipes and saw how good they looked.

They don't seem to be aluminum, which would be a poor choice of material for gears that have to apply a good deal of force. I would guess they are steel. However, you may want to contact Fiskars direct if you are doubtful.

I believe it is aluminum. It is certainly not steel. But it works very, very well and I would buy more.

Not sure, but I believe they are solid copper - one of the threaded holes stripped out too easy to be steel.

No they are aluminum. What you are seeing are plastic sleeves that were there I assume for shipping.

I'm not positive, but upon examining them, they seem like they're stainless. They are holding up well under use.

I believe aluminum. They are very light, but sturdy. This is the size that I like. They are not the narrow one that sometimes are sent.

No this is Aluminum, you can test this by using a magnet, if it is attracted to the magnet it would be steel.

They do not say. They are not cast iron. They feel heavier and sturdier than aluminum, but they are coated with "Calphalon" top and bottom so there is no visual of the metal. My guess would be steel, but that's just a guess.
