Si3N4 silicon nitride mig ceramic welding nozzle



Product Description

Silicon nitride ceramic welding nozzle
The ceramic nozzle we produce is made of silicon nitride,which is widely used in auto welding industry.

The material of welding technology is usually used in extreme environment,should be chosen according to different application,to meet its high wear resistance, high durability, high efficient requirements. 


Silicon nitride ceramics (G.P.S) using in welding.

In welding technology, the silicon nitride materials has its outstanding advantage compared with other metal and non-metallic materials. 

In welding technology, we will use sub-micron high-purity silicon raw material, isostatic pressing technology, sintering when the gas pressure is 100Pa. Silicon nitride has excellent flexural strength, electrical insulation property and high-pressure shock resistance and thermal shock resistance( when room temperature increases from 20 ℃ to 1400 ℃ instantaneously,hot and cold cycles repeat 35 times  the silicon nitride will not be burst).



The advantage of silicon nitride ceramic nozzle; 

  • High hardness
  • High thermal shock resistance
  • Electrical insulating property
  • No cold welding
  • High temperature resistant
  • High toughness
  • High compressive strength

We also produce welding location pins,as below:



The high performance of silicon nitride is that under the high temperature of 800 ℃ , the welding plate and welding nut can accurate matching, it can not be achieved from other materials.  Although ceramic materials such as zirconia and alumina, and metal materials like KCF (ferrochrome) has been used for a very long time. However, silicon nitride as an alternative material, is has many outstanding advantage such as high hardness, high thermal shock resistance, electrical insulation and high temperature,etc.

Reasons to choose ceramic for your parts:

Ceramic parts are used for applications that require wear or corrosion resistance, high temperature capability, or ceramic insulators for electrical resistance.


1. High wear resistance

2. High corrosion resistance

3. Electrical resistance

4. Low thermal expansion

5. High tensile strength

6. Dielectric strength
