Tungsten carbide, an alloy composed primarily of tungsten and carbon, is renowned for its exceptional hardness and wear resistance. It is these properties that make it the ideal material for manufacturing mining button bits. The 'button' refers to the protruding segments of tungsten carbide that are brazed onto the drill bit, creating a robust cutting edge capable of withstanding the intense pressures and abrasive conditions encountered deep within the earth.

FRP ductwork is essentially a composite material made from a combination of thermosetting resin and glass fibers. The resin acts as a binding agent, while the glass fibers provide reinforcement, resulting in a product that is not only strong but also highly resistant to various environmental factors. The ducts are manufactured through a process called filament winding, where continuous glass fibers are saturated with resin and wound onto a mandrel to form the desired shape and size.
