Against the backdrop of the global "dual carbon" strategy and the transformation of the automotive industry towards lightweighting, electrification, and environmental protection, the innovative application of high-performance materials has become the key to enhancing the core competitiveness of automobiles.

Alumina ceramic tubes are a type of high-performance ceramic material with excellent properties such as high temperature resistance, corrosion resistance and wear resistance, thus being widely used in many fields.

In various electric heating devices, ranging from household electric ovens and electric heating tubes to industrial heating equipment that needs to work continuously at high temperatures, you will find that almost all ceramic resistance rods are made of alumina (Al₂O₃) ceramics, especially high-purity 96% or 99% alumina.

In the vast universe of industrial materials, an ostensibly ordinary ring-shaped object is quietly rewriting the rules of the game. It is not metal, yet harder than metal; not plastic, yet more resistant to high temperatures than plastic; not rubber, yet more corrosion-resistant than rubber. It is the alumina ceramic ring, hailed as the "industrial teeth".

Industrial ceramics are almost ubiquitous in industry due to their properties such as high hardness, high strength, high temperature resistance, and corrosion resistance.

Black alumina ceramic is a highly important and widely used advanced engineering ceramic. It is sintered from a high-purity alumina (Al₂O₃) matrix through special processes, such as adding transition metal oxide colorants like MnO₂, CoO, and Cr₂O₃.

Our company will participate in the Shanghai International Heat Treatment and Industrial Furnace Exhibition. If you have any needs for alumina ceramic tubes, please come to the booth to see the sample tubes.

Alumina ceramic is a ceramic material based on aluminum oxide (Al₂O₃), primarily used in thick-film integrated circuits.

The alumina tube in the tube furnace is also called 99 ceramic corundum tube. Its characteristics are as follows.

Alumina ceramic, also known as alumina or aluminum oxide (Al2O3), is an alumna industrial ceramic known for its extreme hardness and high thermal conductivity.
