Specifications of Precision 99% Alumina Ceramic Round Rod

Precision 99% Alumina Ceramic Round Rods offer high performance for demanding technical uses. This material is incredibly hard. It resists wear exceptionally well. The rods are formed from pure alumina powder. This powder is pressed and then fired at very high temperatures. The result is a dense, fine-grained ceramic structure.

The purity level is critical. It is 99% aluminum oxide. This high purity delivers excellent properties. Dimensional accuracy is a key feature. These rods are made to tight diameter tolerances. This precision ensures reliable fit in assemblies. Surface finish is also controlled. The rods exhibit a smooth, consistent finish. This minimizes friction points.

Mechanical strength is outstanding. Alumina ceramic withstands high loads. It resists deformation under pressure. Its hardness rivals many metals. This makes it highly resistant to abrasion. Thermal properties are important. The material handles extreme heat. It maintains strength at temperatures exceeding 1500°C. It also resists thermal shock well. Sudden temperature changes cause less cracking.

Electrical insulation is a major benefit. Alumina ceramic is an excellent insulator. It prevents current flow even under high voltage. This is vital in electronic and electrical applications. Chemical resistance is another strength. The rods are inert to most acids and alkalis. They withstand corrosive environments. This prevents degradation over time.

These rods are dimensionally stable. They do not expand or contract much with temperature changes. This stability ensures consistent performance. They are suitable for harsh conditions. Applications include semiconductor manufacturing fixtures, high-temperature furnace components, precision shafts, wear-resistant guides, and insulating spacers. The combination of purity, precision, and robust properties makes them reliable technical components.

Applications of Precision 99% Alumina Ceramic Round Rod

Precision 99% alumina ceramic round rods offer great performance in tough situations. They are very hard and resist wear extremely well. This makes them perfect for parts that rub together a lot. They last much longer than metal parts in abrasive conditions. You find them in pump seals and valve components. They handle the constant friction without wearing down quickly.

These rods stand up to very high temperatures. They work well in furnaces and kilns. They don’t melt or warp when things get hot. They are used for thermocouple protection tubes and furnace support structures. Heat doesn’t damage them easily.

Alumina ceramic is a very good electrical insulator. These rods stop electricity from flowing. This is important for high-voltage equipment. They are used in insulators and spark plug bodies. They keep electricity safe and contained.

They resist chemical attack strongly. Acids and bases don’t harm them much. This makes them useful in chemical processing equipment. They are used for labware and reactor parts. They don’t corrode like metals do.

The material is also biocompatible. The human body accepts it well. This allows its use in medical devices. Surgical tools and dental implants use these rods. They are safe inside the body.

Precision grinding ensures tight size control. The rods are very straight and round. They fit precisely into assemblies. This is critical for machinery and scientific instruments. Accuracy matters in these applications.

These rods are very stiff. They don’t bend much under load. This dimensional stability is key for gauges and fixtures. They keep their shape under pressure.

They work well in vacuum systems. They don’t release gas easily. This is vital for semiconductor manufacturing tools. Contamination is a big problem there. Alumina rods help prevent it.

The combination of properties makes them versatile. You see them across many industries. Electronics, aerospace, automotive, and energy sectors all use them. They solve problems where metals or plastics fail.
