Global Superhard Material Market Trends and Insights

Precision Machining for EV Lightweight Components

Polycrystalline diamond (PCD) tooling demand is rising as electric vehicle platforms adopt high-silicon aluminum alloys and carbon-fiber-reinforced polymers. Conventional carbide tools wear 10-20 times faster than PCD in these materials. The International Energy Agency recorded 17 million electric vehicle sales in 2024 and expects annual sales to exceed 40 million by 2030. This growth increases the number of aluminum and composite parts that require consistent high-speed machining. The superhard material market benefits from PCD inserts, which enable longer production runs on machining lines designed for these materials. The shift also favors suppliers that can help automotive plants qualify tools for specific grades of aluminum and composite.

Electric vehicles contain 25-30% more aluminum than comparable internal-combustion vehicles, which increases the use of PCD-tipped inserts in high-speed aluminum machining operations. Tool life becomes more important as automated lines reduce tolerance for unplanned tool changes. A longer-lived insert reduces the risk of process interruptions in systems designed to operate continuously. Gigafactory construction adds another source of demand, as reinforced concrete cutting requires diamond saw blades and drill bits. This combination ties the superhard material market to both vehicle production and the industrial buildout supporting electric vehicle manufacturing. It also means that demand for tools can begin before full vehicle output is reached, as construction and equipment installation require cutting and drilling.

Semiconductor Wafer and Thermal Management Processing

Diamond and CBN abrasives are used across semiconductor fabrication for applications ranging from ingot slicing to chemical mechanical polishing and device dicing. Their role becomes more important as substrate materials become harder and more difficult to process. Silicon carbide requires diamond wire saws with controlled grit distribution and reliable electroplating adhesion. These requirements make consistent performance critical in wafer processing. The superhard material market, therefore, has an opportunity in applications where commodity abrasive grades cannot reliably meet process tolerances. Suppliers that understand the full fabrication process can offer more than a basic abrasive product.

Hyperion Materials & Technologies released its Diamond Solutions for Semiconductors guide in July 2026, covering the processing of silicon carbide, gallium nitride, sapphire, and aluminum nitride. The guide reflects the industry's focus on wafer processing as a connected system of tooling. Diamond is also relevant in thermal management applications where high heat transfer is required. The opportunity is linked to advanced substrates and specialized processing rather than standard silicon work alone. This supports demand for higher-value grades, including CVD diamond materials, and increases the importance of application support, quality control, and close collaboration with equipment users.

Energy-Intensive HPHT and CVD Production

HPHT synthesis requires sustained pressures of 5-8 GPa and temperatures of 1,300-1,600°C. Energy use ranges from 36 kWh per carat for open-circuit cooled presses to up to 72 kWh per carat when chilling infrastructure is included. CVD synthesis for specialty diamond grades also carries substantial energy requirements. Energy accounts for a significant share of production costs, particularly for presses and reactors that must operate continuously. The superhard material market is exposed to local power tariffs and the availability of lower-cost electricity. Cost pressure is especially relevant for producers serving price-sensitive abrasive grades.

Continuous thermal operations limit producers' ability to shift work solely to off-peak electricity hours, making tariff changes more consequential for facilities running HPHT presses at scale. Environmental management requirements can add further costs for export-focused producers. Access to renewable electricity may help reduce this exposure, but it does not eliminate the technical need for energy-intensive production. Higher energy costs can compress margins when tool and grit prices cannot adjust at the same pace. Production efficiency and access to electricity remain important operating considerations for the superhard material market. This cost issue applies across basic abrasive output and specialty material production, though the ability to recover costs differs between the two.

Other drivers and restraints analyzed in the detailed report include:

• Reshoring and Automation in High-Value Manufacturing
• Infrastructure-Led Diamond Tool Demand in Asia-Pacific
• Diamond Reactivity with Ferrous Materials and Thermal Limits

Segment Analysis

Extrinsic superhard materials accounted for 60.12% of the superhard materials market share in 2025. HPHT and CVD synthetic production routes support their broad use in abrasive and tooling applications. These materials meet the needs of high-output operations that require consistent grades and repeatable production. The segment is closely tied to the output of synthetic diamond and cubic boron nitride, and its scale makes it relevant for cutting, grinding, drilling, and construction tools. Price pressure exists where high-output abrasive supply exceeds demand, placing a premium on converting material into higher-value products rather than on the sale of basic grit alone.

Intrinsic superhard materials are forecast to grow at a 6.24% CAGR through 2031. This category includes natural diamond single crystals and CVD substrates whose hardness derives from their crystallographic structure. Growth in this segment reflects use in quantum sensing, power semiconductor substrates, ultra-precision optics, and other specialized applications. These uses require controlled material quality and command a higher per-unit value than commodity grit. In June 2026, Element Six and Orbray announced a reproducible process for 3-inch wafer-scale single-crystal diamond, with 4-inch development underway at Element Six's CVD facility in Gresham, Oregon. This announcement highlights the importance of wafer-scale material production for the superhard materials market and illustrates the effort required to move specialty diamond from laboratory-scale capability to dependable, large-scale production. The gap between commodity output and the value available from downstream polycrystalline diamond compact (PDC) composites keeps specialty substrates distinct from the high-output abrasive business. The choice of material type, therefore, affects both technical performance and supplier economics.

PCD held 32.46% of the superhard material market share among cover types in 2025. It is used where wear resistance is required in non-ferrous metals, abrasive composites, and engineered wood. Electric vehicle production supports PCD demand, as aluminum machining is a key application. Its performance in these materials supports consistent machining and longer tool life. PCD is not suited to every metalworking process, as ferrous workpieces present chemical and thermal limitations, leaving its position strong but clearly defined by the material being machined.

PCBN is forecast to grow at a 6.67% CAGR through 2031. Its growth is linked to machining applications involving hardened steel, cast iron, and nickel superalloys that PCD cannot broadly serve. CBN grinding wheels are relevant to brake-rotor finishing and crankshaft machining in automotive production. Sumitomo Electric launched the coated SUMIBORON BNC2135 PCBN grade in January 2025 for interrupted machining of hardened steel, and in April 2026, it launched a binderless end mill featuring ultra-fine CBN grains for precision mold finishing. These launches reflect ongoing product development in grades designed for difficult ferrous and precision-finishing work. The superhard material market requires both PCD and PCBN because their strengths are complementary rather than interchangeable. Diamond materials also serve a specialized purpose in semiconductor polishing compounds and slurry formulations, where controlled abrasive behavior is more important than bulk hardness alone. Cover selection remains linked to machining conditions and the desired surface result.
