A'unavas'rhi or “Made Together”, is a tungsten carbide/titanium alloy that was engineered by the best and brightest of all five clans, as its namesake implies. A'unavas'rhi is a strong metal that is extremely resistant to corrosion and other forms of wear. Tungsten Carbide provides most of the strength and weight while Titanium greatly increases the alloy's resistance to corrosion, electrical current, and heat.
This metal was created out of necessity. The Raiconian Alliance needed a strong metal that would not corrode easily for the Protectors Of The Alliance warships. A'unavas'rhi was the result of countless experiments with various metals. It isn't as strong as the Raiken would have liked, but it was strong enough and it beat out the rest of its competition.
This alloy is used for just about everything due to the readiness of supplies and the relative ease of creating it. More delicate or specialized parts may use a different alloy to suit the specialized purpose.
