Recently, cemented carbide plates have regained industry attention as a critical industrial material, driven by the growing global demand for high-performance materials in manufacturing. Synthesized through powder metallurgy from tungsten carbide (WC) and cobalt (Co), this composite material is hailed as the "super armor" of modern industry due to its exceptional hardness, wear resistance, and corrosion resistance. It is widely used in machining, mining, oil drilling, and more.

Properties and Advantages: Surpassing Traditional Steel

With a hardness exceeding HRA 90—2-3 times that of high-speed steel—and wear resistance dozens of times greater than ordinary alloy steel, cemented carbide plates demonstrate unparalleled durability. Their compressive strength reaches up to 6000 MPa, maintaining stable performance even under high temperatures or corrosive conditions. For instance, crusher liners made of cemented carbide plates in mining machinery last 5-8 times longer than manganese steel counterparts, drastically reducing equipment replacement and maintenance costs.

Innovative Applications: From Aerospace to New Energy

Technological advancements are expanding the applications of cemented carbide plates beyond traditional fields. In aerospace, they are used to manufacture high-temperature components for rocket engine nozzles. In the renewable energy sector, they enable precision cutting of photovoltaic silicon wafers and processing of fuel cell bipolar plates. According to statistics, the global cemented carbide plate market exceeded $5 billion in 2023, with a compound annual growth rate of 6.2%.

Sustainability and Environmental Benefits

The recyclability of cemented carbide plates is emerging as a key advantage. Through specialized processes, 97% of tungsten carbide and cobalt can be recovered and reused from scrap materials, substantially reducing resource waste. Industry leaders like Sandvik and Kennametal have implemented closed-loop recycling systems, driving the transition toward green manufacturing.

Future Outlook

As 5G communications and AI equipment drive demand for precision machining, the development of ultra-fine grain (0.2-0.5μm) cemented carbide plates is accelerating. Experts predict that combining nano-coating technology with 3D printing processes will unlock new applications, providing enduring momentum for industrial innovation.

The evolution of cemented carbide plates epitomizes humanity's quest to push material boundaries. From the depths of the Earth to the vastness of space, this "industrial teeth" continues to bite through the toughest challenges of technological innovation.
