Silicon Nitride（Si₃N₄）
[SNP]

Main Applications

• Molding mold parts (hot forging molds, various molds)
• Casting parts (low pressure castings, various metal melting furnace equipments)
• Die casting machine parts (plungers, sleeves, goosenecks)
• Welding machine parts (guide pin for resistance welding, guide roll for steel pipe weldings)
• Crusher parts (classifiers, airflow type crushers, beads mills)
• Wear resistant parts (wire drawing machine guide rollers, motor shafts, bearings, fishing line yarn paths, wire drawing capstans)
• Semiconductor manufacturing equipment parts (stage parts, linear motors parts)

Features

Silicon nitride (Si₃N₄) is a gray ceramics, it has excellent resistance to thermal shock resistance, and it has a property that it is comparatively hard to get wettability with molten metal.
By utilizing these characteristics, it is used for components used in harsh environments such as internal combustion engine parts of automobiles and torch nozzles of welding machines, especially in harsh environments.

In addition, utilizing high abrasion resistance and mechanical strength to utilize the bearing parts, shafts, bearings and even the effect of low dust generation to be used as parts of semiconductor manufacturing equipment which is required for a clean environment It is.

In addition, we have acquired trademark registration for silicon nitride SNP03 (HSTSiN®) of higher strength and higher reliability than conventional products.
