In modern industrial systems, elongated hard alloy materials are becoming a core foundational material in numerous fields due to their exceptional performance. This strip-shaped material, primarily composed of tungsten carbide and manufactured through powder metallurgy, is reshaping the landscape of high-end manufacturing with its unique properties of high hardness, wear resistance, and corrosion resistance.

Key Application Areas
Precision Molds and Tools: Long strips of cemented carbide are widely used in the manufacture of inserts, guide plates for high-precision stamping dies, and cutting tool inserts. Their stable dimensional accuracy and wear resistance ensure consistency over millions of processing cycles.
Wear-Resistant Components and Guide Rails: In automated equipment and CNC machine tools, they serve as linear guides, sliders, and wear-resistant liners, withstanding high-frequency motion friction and significantly extending equipment lifespan.
Special Process Equipment: In industries such as glass deep processing and ceramic molding, cemented carbide strips are used as shaping molds and conveyor guides, withstanding high temperatures and corrosive environments.
Measurement and Testing Tools: Their extremely low thermal expansion coefficient makes them an ideal material for precision measuring instruments and reference components.
Energy and Mining Equipment: In oil drilling and mining machinery, they serve as wear-resistant liners for critical components, withstanding wear challenges under extreme working conditions.

Technological Development Trends
With breakthroughs in materials science, new types of elongated cemented carbides are developing in a functionalized direction: achieving an optimal balance of hardness and toughness through gradient structure design; the development of nanocrystalline cemented carbides is taking material performance to new heights; and the combination with additive manufacturing technology is opening up new avenues for the direct molding of complex structural components.
From microelectronic packaging to heavy machinery, from precision laboratory instruments to field operation equipment, elongated cemented carbides, with their "industrial backbone" support, are continuously driving the manufacturing industry towards higher precision, higher reliability, and higher efficiency.
