Magnesia Tubes & Rods – High-Performance MgO Ceramics for Thermal & Electrical Applications
M-Kube supplies premium-quality Magnesia Tubes and Rods in Australia, engineered for use in extreme thermal and electrical insulation environments. Manufactured from magnesium oxide (MgO) ceramics, our tubes and rods offer excellent dielectric strength, thermal resistance, and durability, making them ideal for laboratories, furnaces, and high-voltage applications.
We provide two distinct grades of magnesia ceramics designed to suit different industrial and laboratory requirements.
Magnesia Tubes Grades Available
White MgO – High-Density Magnesia (Grade A)
- Superior mechanical strength and low porosity
- Excellent electrical insulation properties
- Withstands continuous operation at high temperatures
- Best suited for thermocouple protection tubes, industrial furnaces, and high-voltage systems
Brown MgO– Standard Magnesia (Grade B)
- Balanced performance for general insulation use
- Good thermal shock resistance
- Suitable for heating element insulation, support rods, and lab setups
- Cost-effective option for general applications
Technical Specification and Typical Elemental Composition: Magnesia Tubes and Rods
| White | Brown | |
| MgO | >=99 | >=997.5 |
| SiO2 | <=0.05 | <=0.70 |
| Al2O3 | <=0.70 | <=0.70 |
| CaO | <=0.70 | |
| Fe2O3 | <=0.05 | <0.70 |
| Na2O | <=0.01 | |
| Density | >=3.3 g/cm3 | 2.9/3.1 g/cm3 |
| Max Temperature | 2000C | 1750C |
In short:
White MgO = High Purity, High Performance (Grade A)
Brown MgO = Standard Performance, More Economical (Grade B)

Product FAQ's
What sizes and shapes are available for magnesia pipes and tubes?
Magnesia pipes and MgO ceramic tubes are available in:
- Outer diameter (OD): 1 mm – 50 mm
- Length: 10 mm – 1200 mm
- Shapes: round tubes, square tubes, multi-bore tubes, and insulating sleeves.
Custom dimensions can also be fabricated by a magnesia tube supplier.
What is the difference between an MgO tube and an MgO ceramic rod?
- MgO tube: Hollow structure, used for thermocouple protection, heating element insulation, and furnace linings.
- MgO rod: Solid structure, used for insulation support, lab experiments, and structural reinforcement.
How much does an MgO ceramic tube cost?
The price of magnesia tubes depends on:
- Dimensions (OD, ID, and length)
- Purity level of MgO material
- Quantity (prototyping vs. bulk orders)
- Supplier and customization level
Generally, small MgO tubes cost a few dollars, while large or multi-bore MgO ceramic tubes cost significantly more.
Are magnesia tubes resistant to chemical attack?
Yes — magnesium oxide tubes are resistant to most alkalis and reducing atmospheres but may react with strong acids and steam at high temperatures. They are commonly used in harsh furnace and metallurgical environments.
What should I check before selecting a magnesia tube supplier?
- Material purity (typically >95% MgO)
- ISO/ASTM certification
- Custom machining capability (multi-bore, thin-wall, long tubes)
- Batch testing reports (thermal conductivity, insulation resistance)
A reliable magnesia tube supplier should also provide fast delivery and competitive pricing.
Can MgO tubes be customized for special applications?
Yes — custom magnesia ceramic tubes can be manufactured in special diameters, multi-bore designs, and thin-wall constructions for:
- Thermocouples
- High-temperature sensors
- Furnace insulation
- Specialized electrical heating systems
What is the lifespan of magnesia ceramic tubes in high-temperature applications?
The lifespan of an MgO tube depends on:
- Operating temperature
- Chemical environment
- Thermal cycling frequency
In controlled conditions, magnesia ceramic insulation tubes can last years in continuous furnace or thermocouple use.
