Brass is a metal alloy of mostly copper & zinc.Bronze is an alloy of mostly copper & tin.Bronze is often redder, stronger, more resistant to corrosion, harder and the making of bronze is much older than brass.
Not a hundred percent sure but what I have found it is pretty strong and if done correct will last and wear well.
As a polymer the properties are: Urea formaldehyde is rigid, strong, brittle and has a high surface hardness, which makes it scratch resistant. It is also heat resistant, as it is a thermosetting polymer. It has a very low water absorption rate, and it is a good electrical insulator. UF has a high tensile strength and it is opaque. this is all that i could find, and it is only for AS level resistant materials.
Melamine is a strong, lightweight plastic-like material. It's dishwasher safe and scratch-resistant. However, Melamine should not be used in the microwave.
No they don't come with scratch resistant lenses.
The screen is very scratch resistant. It would actually have to take a pretty hard knock to scratch it.
No
It is very scratch resistant unless dropped or purposefully damaged.
The table is not scratch resistant but does give you instructions on care and cleaning for you.
The Strand bamboo flooring is scratch resistant, but some dogs will still be able to scuff it up.

It certainly is possible to scratch it, but this stand is scratch resistant and won't scratch easily - but almost nothing out there is really "scratch proof". Generally, no it won't scratch easily.
You can tell if your coat hooks are made of brass by doing a little test. Get a magnet and put it near the coat hook, if it is pulled to the magnet, then it is not real brass also if you scratch it, and it leaves a silver mark then they are not brass, but in fact brass plated. If however you scratch it and it looks kind of yellowish, then it might be brass.
Anon Legion Sunglasses have lenses made from scratch resistant material.
Much residential door hardware is made of brass. However, depending on the quality of the hardware more brass or less brass is used. High quality hardware (for example Baldwin Hardware or Hager Hinge) is made of heavy gauge (thickness) tarnish & scratch resistant brass. Lower quality hardware (for example Kwikset and store branded hardware) is made of thin gauge (thickness) brass. Sometimes lower quality hardware is brass clad steel or brass plated steel.
Brass will oxidize and turn greenish. Moen and Delta have PVD brass finishes which are more resistant to corrosion.
