What is the material plating on the contacts? Gold? Silver? Tin? Copper?

Since the plastic moulding surrounding the contacts is not removable, only the manufacturer(www.hosatech.com) will be able to answer this, but suffice it to say, it gives a solid contact and strong signal. I use it with my laptop so I can utilize my studio headphones, and am very pleased with it's performance.

Not sure, it is silver-colored and has shown no signs of wear so far -- 8 months of in-frequent use getting plugged into and out of my laptop.

I believe its aluminum conductors , I haven't installed my lights yet as I'm waiting for plastic tubing to house my light kit I bought. I peeled some wire and its not copper for sure. Its silver color and non magnetic . Hope this helps you out.

They are metal. Be aware, however, they are not easy to install. If you can't solder or weld find someone that will install them for you before purchasing.

I cannot tell from the text whether you are asking "which is it, metal or plastic?" or "which metal and/or plastic is it?" I cannot answer the second, so will do my best with the first. It appears to be non-conductive paint or plastic over a metal shell. I measure electrical continuity between the added weight screw thread (between the elongated cartridge mount holes) and the rear connector mounting. The metal is not iron; it does not attract a magnet.I hope this helps.

Not sure what others have received, but mine came with very hard contacts that you'll want to solder the wires to.

Metal....aircraft grade aluminum. I think it is better than the plastic one.

Metal. Took the tip of my finger off when I touched it (yes, I reached into the chute).

Metal. I scraped the surface in a small hidden area and it was silver underneath.

I think it's metal incased in a plastic coating. Very good unit, I highly recommend it.

It is metal don't believe they are made of copper just a finish. The rest of the clear tube, and internal funnel tube are plastic.

The nut & insert are brass, the clamp is zinc. I bought these specifically because of the too common, aluminum gold anodized that stores seem to have accepted as the "new" standard. They seem to think cheaper is better without thinking!

It is tin plated steel. Someone in an early post had complained that they had rusted on them. This has not been a problem for me. Just make sure to hand dry the rings after washing. Hope this helps.

They're metal. I would have guessed aluminum, but they're ferrous so probably some alloy.

Plastic housing with metal plate that slides into shoe and of course metal contacts

Definitely metal, just assuming aluminium. There is a DANGER ELECTROCUTION on side panel. A shame, it's a great ladder.

Pry bars are plastic and the drivers are metallic. Great combo for fixing any small electronics.
