Specification of Square Rectangular Solid Al2o3 Alumina Aluminum Oxide Ceramic Stick Bar Rod

Al2O3 alumina ceramic sticks, bars, and rods are incredibly tough industrial components. They are made from nearly pure aluminum oxide. This material delivers outstanding performance in demanding settings. These ceramic pieces resist extreme heat very well. They easily handle temperatures over 1500°C. This makes them perfect for furnace parts and high-heat fixtures.

Their hardness is another major benefit. Alumina ceramic is harder than most metals. This results in excellent resistance to abrasion and wear. Parts last much longer in gritty or sliding contact situations. They need replacement less often. This saves both time and money.

Electrical insulation is a key feature too. Alumina ceramic does not conduct electricity. It works reliably as an insulator in electrical systems. It prevents dangerous short circuits. This property is vital in electronics and power applications.

Chemical stability is crucial. Alumina ceramic resists attack from many strong acids and alkalis. It won’t rust or corrode like metal. This durability ensures consistent performance in harsh chemical environments. It keeps its strength and shape over time.

These ceramic sticks come in standard square and rectangular shapes. Common sizes include 3x3mm, 5x5mm, 10x10mm, 20x20mm, and larger sections. Lengths vary from short pieces to long rods over 500mm. Custom sizes are often available. They fit specific machinery or tooling needs.

You find these alumina rods in many critical places. They serve as thermocouple protection tubes in high-temperature sensors. They are used for grinding media in mills. They act as wear-resistant guides and liners. They function as sturdy electrical insulators. They work as precise fixtures in semiconductor manufacturing. They are essential components in kiln furniture. Their strength and reliability support demanding industrial processes.
