Our magnesium oxide rod is a premium industrial heating element. They are manufactured through a high-pressure automatic extrusion and fired in a 1700℃ tunnel pusher. This process yields a high-density product (2.3 g/ml) with excellent electrical insulation and pressure resistance, comparable to industry-leading suppliers in the US and Japan. They are designed for applications such as cartridge heaters, hot runner heaters, coil heaters, and ceramic tube assemblies (up to 1300°C or even 2400°C under operating conditions).
Key Features Include
- High Density: Manufactured to achieve a density of 2.3 g/ml, ensuring stable insulation and pressure resistance.
- Temperature Capability: Withstands extreme temperatures up to 2400℃, making it ideal for demanding industrial applications.
- Smooth & Uniform Appearance: Finished in a white to off-white matte with flat, burr-free end faces and uniformly distributed holes.
- Versatile Customization: Available in single-hole, double-hole, or multi-hole configurations. Outer diameters range from 2.8 mm to 30 mm, and lengths vary from 250 mm to 350 mm-extendable up to 600-1000 mm per customer needs.
- High Purity: The MgO content ranges from 98.19% to 99.56% (up to 99.8% for select products) based on GB/T 6900-2006 & GB/T 5069-2015 standards.
- Enhanced Properties: Offers low electrical conductivity, high thermal conductivity, excellent corrosion resistance, and infrared transparency.
