probably in taiwan where most bikes are made
Most mountain bikes are made from Aluminum, some are made from carbon fiber and older bikes are made from steel. Quality, weight and strength vary hugely by manufacturer with most high end bikes claiming unique methods which either reduce weight, improve strength or both.
If you mean Sunn, they are a French company, but as with most bicycle companies, the majority of their bikes are actually made in Asia.
Aluminium and steel
Yes as are most bikes these days, but not in top road or mountain bike class. They are a USA icon but now, like most bikes, are made in China or Taiwan.

Most bikes and bike parts are made in Asia, although there's still a decent number of bikes that gets final assembly in the US/Europe.
They're made from the same basic stuff as most other bikes are made of, no difference there.
Not unless they have grit and stones trapped in the tire treads.... But metals start out as minerals, and most bikes are made from metals.
