High Hardness Si3N4 Positioning Pin Silicon Nitride Ceramic Dowel Pin For Welding
1 . Description
High Hardness Si3N4 Positioning Pin Silicon Nitride Ceramic Dowel Pin for Welding refers to a type of ceramic dowel pin that is used in welding applications. It is made of a material called silicon nitride (Si3N4), which is known for its high hardness, strength, and resistance to wear and corrosion.
These ceramic dowel pins are used to precisely align and position parts during the welding process, ensuring a high degree of accuracy and consistency. They are typically used in resistance welding and other types of welding applications where precision and repeatability are critical.
The high hardness of silicon nitride ceramic makes it ideal for use in welding applications, as it can withstand the high temperatures and pressures generated during the welding process. It is also non-conductive, which helps to prevent electrical arcing between the dowel pin and the workpiece.

2 . Silicon Nitride Ceramic Properties
Silicon Nitride Ceramic Properties Color: Gray and Gray-black
Density: 3.2~3.25 g/cm3
Hardness: HRA 92~94
Highest Operating Temperature: 1300 ~1600 ℃
Thermal Conductivity: 23-25 W.(M.K)-1
Bending Strength: ≥ 900 Mpa
Fracture Toughness: 6~8 (Mpa.m1/2)
Thermal Expansion Coefficient (at 0~1400℃): 2.95~3 ×10-6/℃
Because silicon nitride welding pins are electrically insulated, unnecessary current can be completely avoided, sparks are avoided between ceramic pin and the workpiece, and the slag removal work during the welding process is reduced; the high wear resistance and high fracture toughness of silicon nitride ceramic enables the workpiece to be accurately positioned for a long time. The welded workpiece maintains a very high quality and high yield, reducing the frequency of locating pin replacement and improving production efficiency.
