Because metals are usually good conductors of heat. When you touch metal at
a spot that's cooler than your skin, the bit of heat that flows from your finger
to the metal at that spot quickly flows onward to cooler parts of the metal ...
leaving that spot still cool, and still taking heat out of your finger.
If you waited around until the entire piece of metal warmed to the temperature
of your skin, then the metal wouldn't feel cool any longer.
Your body is mostly made of water. When you touch a very cold object, for example ice or metal, it freezes the water in your fingers and the object together. This can only happen with anything with a little bit of moisture on it: ice does not stick to dry objects, as there is no water there to freeze. -- Cucarach1 its not :/

Dunk it in liquid nitrogen.
Cold rolling produces a better finish and is generally used for automotive body panel sheet metal. See link
Cold metal.
Metal conducts heat very well; the heat of your feet will be carried away quickly on a metal floor, causing you to feel cold - because of the loss of heat. Wood conducts heat very POORLY; it's an excellent insulator. That's why we use wooden "trivets" to protect delicate tabletops from hot cooking vessels.
If it a piece of metal or any hard object that cold damage the engine, you need to remove the intake manifold and then remove the object. Unless it is a very tiny soft object, you need to get it out.
Cold Metal was created in 2001.
A cold object is more dense.
heat travel from a hot object first then to cold object!
A cold object is something that when touched, appears to feel cold. Another meaning of a cold object is something that when touched or used to touch something with, may turn that object in question colder or even freeze it.
No, thermal energy always transfers from a relatively hot object to a relatively cold object. This is because, when heated, atoms have more kinetic energy, and they pass this down to the "colder" particles, which have a lesser degree of kinetic energy.
