# Cemented Carbide: The Preferred Material for Industrial Manufacturing

In the industrial manufacturing sector, material selection directly determines product performance, service life, and processing efficiency. As a metal matrix composite with tungsten carbide (WC) as its core constituent, cemented carbide—owing to its unique physicochemical properties—has become an indispensable “industrial tooth” in modern industry. From precision cutting tools to mining drilling, and from aerospace to electronics manufacturing, cemented carbide finds applications across nearly all high-end manufacturing domains. Ongoing technological advancements and evolving market demands are driving global industry toward greater precision and higher efficiency.

## I. The “Hardcore” Properties of Cemented Carbides: A Perfect Combination of High Hardness and Wear Resistance

The core advantage of cemented carbides lies in their exceptionally high hardness and wear resistance. Take tungsten carbide as an example: its microhardness can exceed 1,800 kg/mm², approaching the hardness level of diamond. This remarkable property stems from its unique crystal structure: carbon atoms occupy the interstitial sites within the tungsten lattice, forming an interstitial solid solution that renders the crystal structure extraordinarily stable. Even under severe thermal conditions, cemented carbides maintain consistent performance—retaining nearly unchanged hardness at 500°C and sustaining high hardness up to 1,000°C, far surpassing traditional materials such as high-speed steel.

In terms of wear resistance, cemented carbide tools last 5 to 80 times longer than high-speed steel tools, while their service life in mold applications is 20 to 150 times that of alloy tool steels. For example, in the machining of automotive engine cylinder blocks, cemented carbide cutters can sustain continuous cutting over tens of thousands of meters without significant wear, whereas conventional tools typically manage only a few hundred meters. This exceptional performance makes cemented carbide the material of choice for machining hard materials such as stainless steel and high-manganese steel.

## II. From the Laboratory to the Production Line: Breakthroughs in Cemented Carbide Manufacturing Processes

The production of cemented carbides requires precise control through powder metallurgy processes. The process includes:

1. **Raw Material Preparation**: Mix hard-phase powders such as tungsten carbide (WC) and titanium carbide (TiC) with binder-phase powders like cobalt (Co) and nickel (Ni) according to a specified ratio, ensuring that the particle size is controlled within the 1–2 μm range.

2. **Wet Grinding and Mixing**: The materials are thoroughly mixed in an alcoholic medium using a ball mill to ensure uniform distribution of the hard phase and the binder phase.

3. **Pressing and Molding**: The mixture is pressed into green bodies of the desired shape, with a density reaching at least 95% of the theoretical value.

4. **High-Temperature Sintering**: Sintering is carried out in a vacuum or hydrogen atmosphere at 1300–1500°C, causing the binder phase to melt and coat the hard-phase particles, thereby forming a dense microstructure.

In recent years, emerging technologies have continuously driven advancements in manufacturing processes. For example, a team from Beijing University of Technology has developed an “amorphous‑to‑crystalline + reactive transformation” technique that, through the rapid crystallization of amorphous precursors, produces ultrafine‑grained cemented carbides with grain sizes as small as 600 nanometers, achieving a hardness of 2143 kgf/mm² and an improved fracture toughness of 9.7 MPa·m¹/². Meanwhile, South China University of Technology has introduced a “one‑step carburization sintering” method that employs discharge plasma‑assisted high‑energy ball milling to simultaneously carry out WC carburization and alloy densification, shortening the production cycle by 40% and reducing energy consumption by 30%.

## III. Comprehensive Coverage of Application Scenarios: Cemented Carbide as an “Industrial All-Rounder”

The application of cemented carbides has permeated every stage of industrial manufacturing:

1. **Cutting Tools Sector**: Accounts for more than 50% of global cemented carbide consumption. Turning tools, milling cutters, drills, and other cutting tools are extensively used in the precision machining of automotive and aerospace components. For example, when machining aircraft engine blades, cemented carbide tools can achieve surface roughness control at the 0.01 mm level.

2. **Mining and Engineering Tools**: Hardmetal tools such as roller‑cone drill bits and downhole drilling assemblies have demonstrated significant efficiency gains in geological exploration and oil‑and‑gas extraction. A hardmetal containing 1.0% WCoB ternary boride exhibits wear resistance more than twice that of conventional materials, with a service life extended to 12 months.

3. **Wear-Resistant Components**: In applications such as wire-drawing dies, rolling mills, and nozzles, the wear resistance of cemented carbides helps reduce equipment downtime. For example, in the cold-rolling process of the steel industry, cemented carbide rolls have a service life five times that of conventional rolls.

4. **Expansion into Emerging Fields**: With the advancement of 3D printing technology, electron beam selective melting has enabled additive manufacturing of cemented carbides, paving the way for rapid prototyping of complex‑shaped components. Moreover, cemented carbide coating technologies—such as TiN and TiAlN coatings—have further extended tool life by 3 to 5 times, making them widely used in high‑precision applications like machining battery housings for new‑energy vehicles.

IV. Market and Industry Landscape: China Leads Global Cemented Carbide Development

China is the world’s largest producer and consumer of cemented carbide. In 2024, China’s cemented carbide output reached 60,000 tonnes, with a market size exceeding RMB 45 billion, accounting for more than 40% of the global market share. Leading companies such as Zhuzhou Cemented Carbide Group and Xiamen Tungsten have driven the industry toward higher‑end applications through technological innovation and capacity expansion. For example, Zhuzhou Cemented Carbide Group has developed ultrafine‑grained cemented carbides that have achieved import substitution and are widely used in cutting‑edge fields like semiconductor chip manufacturing.

However, the industry continues to face challenges. In 2026, constrained tungsten raw material supplies drove a 25% year-on-year increase in tungsten carbide powder prices, prompting upward revisions in cemented carbide product pricing. In response, companies are cutting costs by optimizing processes and improving material utilization. Meanwhile, as the “dual carbon” goals gain momentum, green manufacturing has emerged as a new strategic direction, with low‑energy sintering technologies and the recycling and reuse of spent cemented carbides attracting widespread attention.

## V. Future Prospects: The Path of High-Precision, Cutting-Edge Evolution for Cemented Carbides

Looking ahead, cemented carbides will evolve toward higher performance and greater intelligence:

1. **Nanofication and Composite Design**: By incorporating nano-sized particles (such as Cr₂(C,N)) or engineering a dual-scale grain structure, both hardness and toughness can be simultaneously enhanced.

2. **Functional Coatings**: Develop adaptive coating technologies that enable cutting tools to automatically adjust their surface properties under varying machining conditions.

3. **Digital Manufacturing**: Integrating AI algorithms to optimize sintering process parameters, enabling precise control over the performance of cemented carbides.

4. **Green and Sustainable**: Promote low-carbon technologies such as hydrogen reduction and microwave sintering to reduce carbon emissions during the manufacturing process.

The story of cemented carbide is a legend written in tandem by materials science and industrial demand. From 1923, when German scientist Schröter invented the first tungsten carbide–cobalt alloy, to today—when it underpins strategic industries such as aerospace and new energy—cemented carbide has consistently demonstrated its “hardcore” prowess, embodying the value of “industry’s cutting edge.” Amid the sweeping tide of manufacturing modernization, cemented carbide will undoubtedly continue to play a pivotal role, propelling humanity toward an era of ever-higher‑precision industrial civilization.
