The ultimate solution for high temperature, corrosion, insulation and precision components - providing reliable support for industrial, electronic, medical and aerospace applications! 


The 3mm ceramic rod is a small, cylindrical rod made from ceramic materials, typically known for their excellent properties like heat resistance, electrical insulation, hardness, and wear resistance. Ceramic rods are used in various applications across industries, including manufacturing, electronics, and engineering, due to these unique qualities.

3mm ceramic rod is a high-performance component used for its heat resistance, electrical insulation, and hardness. It is commonly found in industrial machinery, electronic devices, aerospace, automotive applications, and more, especially where durability, precision, and resistance to harsh environments are required. However, its brittleness and higher cost compared to other materials can limit its use in some applications.


Key Properties of a 3mm Ceramic Rod:

  1. Diameter:

    • The rod has a 3mm diameter, making it suitable for precision applications where small, thin components are required.

  2. ● Material:

    • Ceramic rods are made from materials like alumina (aluminum oxide), zirconia (zirconium dioxide), or silicon nitride, depending on the application. These materials offer high strength, corrosion resistance, and thermal stability.

  3. ● Heat Resistance:

    • Ceramic rods can withstand high temperatures (often exceeding 1000°C), making them ideal for use in high-heat environments like kilns, furnaces, and heat exchangers.

  4. ● Electrical Insulation:

    • Ceramics are excellent electrical insulators, meaning they do not conduct electricity. This property is important in electronic and electrical applications where insulation is necessary.

  5. ● Hardness and Wear Resistance:

    • Ceramic materials are extremely hard and have high wear resistance, making them suitable for abrasive environments or where high mechanical durability is needed.

  6. ● Corrosion Resistance:

    • Ceramic rods are highly resistant to chemical corrosion from acids, alkalis, and other harsh environments, making them useful in chemical processing industries.

  7. ● Lightweight:

    • Despite their hardness and durability, ceramic rods are relatively lightweight, making them easier to handle in precision applications.


Why choose 3mm ceramic rods? 

Extreme Heat Resistance: Continuously withstand high temperatures up to 1000°C+ without deformation or failure (preferred for furnaces/engines).

100% Insulation: completely isolate the current, to ensure the safe operation of precision circuits.

Superior abrasion resistance: hardness of 8-9 on the Mohs scale, resistant to particles and mechanical abrasion.

The king of corrosion resistance: no fear of strong acid, alkali, solvent erosion (chemical/medical ideal materials)

Precision and stability: 3mm diameter ±0.05mm tolerance, suitable for microstructure assembly.
