Tungsten carbide is a hard, brittle material created up of ETI tungsten and carbon atoms. It’s categorized like a metalloid, indicating it has qualities of both of those metals and non-metals.
Spartan Armor units® multi-strike ceramic armor is durable and will stand up to numerous hits, which is important for regulation enforcement and navy staff who could be exposed to several threats.
As of 2015, boron carbide is definitely the third hardest compound identified, just after diamond and cubic boron nitride, earning it the nickname “black diamond”.
to the Mohs hardness scale, calcium carbide only ranks between a three and 4, making it one of many softer carbides. on the other hand, it’s still more durable than most metals and alloys, which makes it appropriate for use as an abrasive material for particular applications.
Its distinctive Homes make it The most useful and flexible materials in different superior-tech industries.
