Luna Titanium Alloy

Luna Titanium is a fictional substance from the Original Series used to construct the famous RX-78-2 Gundam.

Development
When the Earth Federation designed the RX-78 series of mobile suits, they had to use a material that was strong, lightweight and durable; they could only afford to make a few mobile suits with their given production facilities. Titanium couldn't be used, as it was brittle if subjected to large amounts of stress over time, so they went with doing quality over quantity and decided on using a metal that was used in thermonuclear reactors at the time.

Effectiveness
The Luna Titanium armored RX-78-2 Gundam was almost unstoppable in combat, 120mm and 90mm shells fired from the Zaku's machine guns had almost no effect on the alloy. During a fight with the Gundam on Luna II, Zeon pilot Char Aznable said that he 'hadn't seen a mobile that could survive the beating I'm giving it'.

Qualities
1. Lightweight; the Zeon Zaku weighed slightly more than the Gundam.

2. Durable; projectile weapons could only scratch the alloy, which proved to be a disadvantage as most Zeon mobile suits were only equipped with machine guns or bazooka's. (The 360mm Bazooka used by the MS-09 Dom had the ability to do moderate damage due to the large explosive charge but the shells could easily be evaded at long range.)
