Mingrui Ceramic is able to manufacture alumina ceramic rods in any size and shape according to customers' requirements. The dimension tolerance of the alumina rod is up to 0.001mm, and its max working temperature is up to 1750℃, and it's cleanable, reusable, and environmentally safe.
Due to the excellent physical and chemical performance, our alumina ceramic rods can be used in industries such as mechanical engineering, aerospace, electronics, furnace, chemical engineering, energy and power engineering, smelting, and semiconductor. We will use the most suitable material to meet the application requirements of customers.
Al2O3 Ceramic Rods have a wide range of applications. Al2O3 ceramic rods of different sizes are required in many industries. For custom manufacturing, please contact us for more information.
Features
• High precision
• High corrosion resistance
• High hardness
• High oxide & wear resistance
• High acid & alkali resistance
We are a professional manufacturer of Alumina ceramic insulating rods, custom manufacturing different specifications of ceramic parts, according to the parameters or drawings provided by the customer.
"Precision ceramics", "technical ceramics", and "advanced ceramics" are all terms that encompass the ceramics that provide us with high-performance mechanical, thermal, or electrical properties. They are very suitable for being applied to extreme application environments involving high temperature, high friction, high voltage, and high compressive load due to their excellent properties.
This datasheet shows the main properties of the ceramic materials we use. It will help you find the material you need by understanding the relative properties of each material.
If you want to know more in-depth information, or you need technical support from our experienced engineering team, please contact us.
