Tungsten Nickel Copper Supplier in Japan

Pioneering Metallurgy Since 2001

Established in 2001, Zhuzhou Jiuding Metal Technology Co., Ltd is a professional joint venture company which engages in manufacturing, machining and sales of tungsten heavy alloy, tungsten copper, cemented carbide, pure tungsten and other relevant tungsten alloy products.

Our comprehensive portfolio mainly includes high-density tungsten heavy alloys, tungsten carbide, tungsten alloy fishing sinkers, tungsten darts, tungsten alloy swaging rods, bucking bars, copper tungsten electrodes, tungsten alloy bullets, tungsten alloy syringes, shielding vials, and boring bars.

Due to their exceptional characteristics of high density, high hardness, high melting point, anti-corrosion, radiation protection, non-toxic and environmental-friendliness, our materials are highly demanded across Japan's advanced industrial sectors. We supply premium materials to major industrial hubs including Tokyo, Osaka, Nagoya, and Fukuoka, ensuring compliance with strict Japanese industrial standards.

Our technological innovation enables the precise pre-control of shell fragments. By utilizing advanced grooving techniques or optimizing the lining of explosives, we manage the structural integrity of the shell. This ensures the controlled dispersion of uniform, highly effective fragments upon detonation.

Prefabricated fragments, such as steel balls, steel arrows, tungsten balls, and tungsten columns, are pre-designed in shape and mass. These are integrated into the inner or outer surfaces of grenade projectiles. Upon detonation, they create a highly concentrated and predictable fragmentation field, maximizing lethal efficiency and structural consistency.

Because prefabricated fragments can affect the structural integrity of a missile body, they are typically applied in specialized low-pressure chamber systems, such as forced large-caliber artillery and grenades. However, modern high chamber pressure systems, such as the Swiss L70-type 40 mm grenade, now incorporate tungsten carbide ball matrices to withstand extreme operational forces.

Tungsten columns, due to their exceptionally high density and armor-piercing capabilities, are extensively used as active elements in air defense, anti-radiation, and anti-surface systems.

Beyond military applications, our tungsten alloy products are widely utilized in aerospace, medical equipment, electronics, oil exploration, automotive damping, and luxury consumer goods. Using state-of-the-art Metal Injection Molding (MIM) and advanced powder metallurgy pressing technologies, we manufacture complex, non-standard custom components to meet the precise requirements of our Japanese clients.
