1 . Description

Silicon nitride (Si3N4) ceramic welding pins are used as location pins in projection welding to allow precise welding of nuts to sheet metals. They are solid ceramic pins made of ultra-hard material silicon nitride ceramic, machined with smooth surface and precise sizes. The excellent properties of high hardness, high strength and good wear resistance make silicon nitride ceramic the toughest material for ceramic welding pins.

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.
