1 It is recommended that beginners play an easier Difficulty first, before attempting hardcore mode. 2  Do not enter Caves unless prepared with at least iron Armor, a Sword and a Pickaxe.  Do not go to The Nether or The End unless totally prepared.
Tungsten Carbide Education: What is Tungsten Carbide. Tungsten carbide (WC) is durable and hard, it is four times harder than titanium, ten times harder than ceramic and twice as hard as stainless steel, so it cannot be resized.
Tungsten's melting point of 3422 Â°C is the highest of all metals and second only to carbon (3550 Â°C) among the elements. This is why tungsten is used in rocket nozzles and reactor linings. There are refractory ceramics and alloys that have higher melting points, notably $\ce{Ta4HfC5}$ with a melting point of 4215 Â°C, hafnium carbide at 3900 Â°C and tantalum carbide at 3800 Â°C. Carbon cannot be used to hold molten tungsten because they will react to form tungsten carbide.
