#126: Unbihexium, also known as Durasteel.
Melting point: 3901 C Boiling point: 8412 C Density: 16.63 G/cm^3 Symbol: Du A metalloid with 3x the strength of steel, a slightly higher melting point then tungsten, and durable enough to be used in bladed weapons and armor. gray with a hint of blue
#127: Unbiseptinium, Also known as Aegisalt
Melting point: 1653 C Boiling point: 1930 C Density: 7.8 G/cm^3 Symbol: Ai A light green metal that forms giant cubic crystals. It has a very high electrical conductivity, which makes it great for energy weapons, tools, and machinery. It’s not very sturdy though, so it makes a poor armor without a reinforcement.
#128: Unbioctinium, also known as Violium
Melting point: 1830 C Boiling point: 2233 C Density: 4.214 G/cm^3 Symbol: Vo A purple metal, able to withstand extreme forces when honed down to a blade. it can get as sharp as obsidian, if not sharper. It’s an excellent metal for swords and armor, and has a high thermal conductivity. don’t wear it on a hot day.
#129: Unbiennium, also known as Ferozium
Melting point: 2874 C Boiling point: 10341 C Density: 13.632 G/cm^3 Symbol: Fz A bright blue crystalline metal. It’s very brittle, but has a low thermal conductivity. It’s been known that, imbued with another element, it conducts an extreme amount of electricity. otherwise, it’s a terrible conductor.
#130: Untrinilium, also known as Solarium
Melting point: 500 C Boiling point: 3012 C Density: 7.77 G/cm^3 Symbol: So A bright yellow mineral. it’s a radioactive metal when natural, but can alloy with other elements and Durasteel to make tough, almost supernatural alloys. It has a half-life of 2.75 billion years, and decays into Ferozium-366
Alloy 1: Rubium (Fz2So3Du)
Melting point: Unknown Boiling point: unknown Density: 1.3 g/cm^ A crimson red alloy of Ferozium, Solarium and Durasteel. Rubium has an extremely high thermal conductivity, acts as a superconductor, and is as strong as Violium. It is best used for high-end staff weapons. Because of it’s thermal conductivity, it is extremely hard to get a good temperature reading on it.
Alloy 2: Cerulium (AiSo2Du3)
Melting point: 4092 C Boiling point: Unknown, beyond 12500 C Density: 5.42 G/cm^3 A deep blue alloy of Aegisalt, Solarium, and Durasteel, Cerulium is unique in that it can store a lot of energy, and thus, used as a high-capacity capacitor. it’s a soft crystal otherwise.
Alloy 3: Impervium (Vo3So3Du2)
Melting point: 2501 C Boiling point: 4123 C Density: 35.52 G/cm^c
A dark grey alloy of Violium, Solarium, and Durasteel, Impervium is an extremely heavy alloy, and has an extreme resistance to damage. blades like this can cut through cells due to how sharp it can get. It’s rarely used as an armor due to how heavy it can get. Doesn’t absorb heat very well, and is an excellent insulator for electricity as well.
