Annealing is the process of slowly raising the temperature about 50 ºC (90 ºF) above the Austenitic temperature.
It is held at this temperature for sufficient time for all the material to transform into Austenite or Austenite-Cementite as the case may be. It is then slowly cooled at the rate of about 20 ºC/hr (36 ºF/hr) in a furnace to about 50 ºC (90 ºF) into the Ferrite-Cementite range. At this point, it can be cooled in room temperature air with natural convection.
the process is used to soften the metal so that you can work on it without it fracturing or generally to make it more maliable.
In addition to the process above, you can also anneal metals as follows:-
Normalising: raised to 60 degrees, to completely convert the metal to Austenite.
Process: used on work hardened metals to return the soft maliability for further cold working without the metal fracturing.
Stress relief: reduces residual stresses in large castings
Spheroidisation: used to treat high carbon steels which are going to be machined or cold formed.

Tin itself is a Non-Ferrous metal however Tin Plate is a ferrous metal
Ferrous metal means a metal containing at least some iron. So pig iron must be a ferrous metal.
Aluminum is a non ferrous metal.
No, Its Non-ferrous

Non-ferrous.
1. Ferrous metal 2. Non-Ferrous metal 3. Alloys
Ferrous metal is any metal that contains iron.Iron is attracted the a magnet.So to test if metal is ferrous pass a magnet close to it, if the magnet reacts then you have ferrous metal.
to make ferrous metal all you have to do is mix iron with a certain type of metal to make a non ferrous metal well you don't have to any metal that doesn't have iron in it is a non ferrous metal

Bronze is an alloy not a metal. It does not contain iron so is "non ferrous".
Ferrous metals contain iron in appreciable amount. There is no iron in gold. So gold is non-ferrous metal.
