Why is tungsten carbide one of the hardest materials to forge?
Tungsten carbide a brittle ceramic. If you tried to forge it then it’d shatter. Unlike glasses, which tend to have convenient softening temperatures, tungsten carbide doesn’t soften at a reasonable temperature. It’s a high temperature material.
Yes, tungsten carbide does have a metallic binder (cobalt, nickel, etc.), but the volume of the binder is so small that it doesn’t support the flow and movement of the brittle tungsten carbide filler during forging.
The problem is common in ceramics. Most ceramics can’t be forged for the same reasons as tungsten carbide. Instead, you sinter them from a powder into their final shape, or to a “near net shape” condition and machine them to a desired finish and desired dimensions.
