Product Description

Nextgen Advanced Materials INC is a professional leading Silicon Nitride Welding Pin manufacturer with high quality and reasonable price. Welcome to contact us. Silicon nitride welding pin is made of a high-melting-point ceramic material that is extremely hard and relatively chemically inert. Due to the even performance in high temperature, Si3N4 is a commonly used ceramic material in the metallurgical industry. It has excellent thermal shock resistance due to the microstructure. The creep and oxidation resistance of Si3N4 is also superior, its low thermal conductivity and high wear resistance also make it an outstanding material that can withstand conditions of most industrial applications.
