* Steel: The hull, bulkheads, and most of the internal structure were made of steel. This was a relatively new material at the time, and its use was one of the reasons why the Titanic was considered such a marvel of engineering.
* Iron: While steel was used for the primary structure, some components like the boilers and some machinery were still made of iron.
* Wood: Timber was used for many interior fittings, including the decks, furniture, and even some of the lifeboats.
* Other Materials:
* Brass: Used for decorative elements, fixtures, and some fittings.
* Copper: Used for piping and other plumbing.
* Leather: Used for upholstery and some decorative elements.
* Glass: Used for windows and mirrors.
It's important to note that while the Titanic was a magnificent ship, the quality of some materials used was not as high as it could have been. For example, the rivets used to hold the hull together were of a weaker quality than those used in other ships. This was a factor in the ship's disastrous sinking.
