Related introduction:
In the first Iron Man movie, Tony, who was arrested by a terrorist attack, made a mark 1 generation in a cave. This suit is made of ordinary alloy steel. Later, after escaping with Mark 1 armor, he built the second generation of pure silver Mark, which is still an ordinary alloy steel.
During the test flight, Tony challenged the strength of the armor, but when it rose to a certain height, the problem of whole body icing became obvious. Therefore, starting from the third generation of Mark, the material of armor was changed to gold-titanium alloy, one for freezing protection, and the other for strengthening the protective ability of armor compared with the previous two generations.
