It features high overall rigidity with outstanding bending and deformation resistance. Through cold isostatic pressing, vacuum sintering and precision grinding, micron-level control of diameter, straightness and tip radius can be achieved (straightness is typically within ±0.005 mm, surface roughness Ra < 0.2 μm), meeting the high-precision requirements of semiconductor, medical device and other high-end fields.
Carbide Needle
It can reach a hardness of HRA 88–92 at room temperature, much higher than high-speed steel. The tungsten carbide hard phase has extremely high hardness, resulting in minimal wear under repeated friction, cutting, electrical discharge and other working conditions. Its service life is dozens of times longer than that of ordinary metal needles, making it suitable for long-term continuous operation in precision molds, discharge electrodes, probes and other applications.
