Since copy coins don't have any standards, anyone can make a copy coin out of any material (lead, zinc, gold, silver, copper, etc.) only a coin dealer or jeweler who sees your coin in person can guess at what it is made out of. It has no collector value, the only value comes from the metals used to make it. Most are just gold-plated copper and have no value though.
The metal disc used to make a coin is called a "coin blank" or, more formally, a "planchet." They also used to be called "flans," but that term is no longer as widely used.
Velour material is material used to make tracksuits etc.
The first bomb that was used on people (Little Boy) used Highly Enriched Uranium as its fissile material. The first tested bomb at the Trinity Test used Plutonium as its fissile material.
Beach scarves make good towels, but check the material first to make sure it can handle the water.
The properties must be considered first so that it will be able to make the product.
