From 2025 Sep. to 2026 March., the price of tungsten powder has experienced significant fluctuations(tungsten powder price rise from $80 to $340 per Kg. 4 times higher), and in certain periods it has risen sharply. Because tungsten is the core raw material used to produce tungsten carbide, this directly affects the manufacturing cost of carbide cutting tools. For industries that rely heavily on precision cutting—such as paper, film, foil, battery materials, textiles, and corrugated board—these price increases inevitably influence purchasing decisions and equipment strategies.
For many end users in the slitting and converting industry, the first concern is simple: maintaining stable production efficiency while controlling tool cost. Cutting tools are consumables in continuous production lines, so even small increases in tool prices can have a noticeable impact on operating expenses over time. As a result, when tungsten carbide tools become more expensive, many manufacturers begin exploring alternative approaches rather than relying solely on solid carbide knives.
One of the most common adjustments is the temporary shift from tungsten carbide knives to high-speed steel (HSS) blades in less demanding applications. Although HSS tools do not offer the same wear resistance or edge retention as carbide, they are significantly cheaper and easier to regrind. For some materials—such as thin films, paper, or low-abrasion plastics—HSS knives can still provide acceptable performance when production speeds are moderate.
Another widely used solution is brazed or welded carbide edge knives. Instead of manufacturing the entire knife from solid carbide, only the cutting edge is made from tungsten carbide and then brazed onto a steel body. This hybrid structure dramatically reduces the amount of carbide material required while still maintaining a durable cutting edge. Many converters consider this a balanced solution during periods of high raw material costs.
Some factories also extend the life of existing knives by improving their maintenance and regrinding cycles. By introducing stricter blade inspection procedures, optimizing grinding angles, and using professional reconditioning services, companies can significantly increase the number of times a knife can be reused. In high-volume slitting operations, this approach can reduce tool consumption without sacrificing product quality.
Operational adjustments can also play a role. Some production managers optimize slitting pressure, blade alignment, and machine speed to reduce unnecessary edge wear. Even small improvements in machine setup can extend blade life and minimize the frequency of replacements. In addition, certain manufacturers choose to keep a mixed inventory of knives—using carbide tools only for the most abrasive materials or high-precision jobs, while assigning lower-cost alternatives to lighter tasks.
These behaviors clearly reflect the practical thinking of downstream users: maintaining productivity while spreading the cost of tungsten carbide over a longer period.
For suppliers of tungsten carbide slitting solutions, such market conditions require a more flexible approach rather than simply competing on price. At Huaxin (Chengdu Huaxin Cemented Carbide Co., Ltd.), our response focuses on helping customers maximize the value of carbide tools rather than merely selling more of them.
One important direction is material optimization. By improving carbide grain structure and binder composition, higher wear resistance can be achieved without significantly increasing carbide consumption. This allows knives to last longer in demanding slitting environments such as lithium battery foil, packaging films, and corrugated board production.
Another strategy is precision manufacturing. The cutting performance of a slitting knife is not determined by material alone. Grinding accuracy, edge geometry, and dimensional stability all influence how efficiently a blade cuts and how slowly it wears. High-precision knives reduce friction and produce cleaner cuts, which indirectly extends service life and lowers the cost per cut for the user.
Huaxin also works with customers to develop application-specific knife solutions. Different industries require different edge designs, thickness tolerances, and hardness levels. By tailoring knives to specific materials and slitting conditions, it is possible to significantly improve durability and reduce overall blade consumption.
The cutting industry has always adapted to changes in raw material markets. While rising tungsten prices encourage experimentation with alternative tools, high-performance carbide knives remain irreplaceable in many precision and high-speed slitting applications. The key for suppliers is not simply offering carbide products, but delivering solutions that help customers achieve the best balance between cost, durability, and cutting performance.
