Luna Titanium Alloy

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

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. 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.)
