Alumina Rod


What is Alumina Rod?

Alumina, also known as Aluminium Oxide, is a chemical compound comprised of Aluminium and Oxygen molecules. It is produced from Bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. When refined from Bauxite, Alumina generally looks like a white powder similar to salt or sugar.

Alumina is mostly known for producing Aluminium. However, this material is also the most widely used oxide ceramic material. Other uses include use as a filler for plastics or as an additive in automobile paints. Rods are a widely used format, as it allows consumers to machine and shape the Alumina to their needs. The rods may be used to produce pieces, such as spark plugs, tap washers, abrasion resistant tiles or cutting tools.

Properties of Alumina Rod

Key properties of the material include high hardness and good wear resistance; therefore, it is not easily damaged by friction or use. In addition, it’s resistant to high temperatures for prolonged periods of time as well as being highly corrosion resistant. The electrical insulation performance of Alumina is particularly outstanding at high temperatures. However, Alumina Rod has the disadvantage of low thermal shock resistance and the inability to withstand rapid temperature changes. Another important property of Alumina is that it is chemically inert and is not corroded by water or steam, offering good resistance to strong acids and alkalis.

Production capabilities for Alumina include isostatic and dry pressing, low pressure injection moulding, extrusion, slip-casting and CNC machining. Alumina Rods are machinable for applications in which high temperature insulation or thermal shock resistance are required. A wide variety of ceramic processing methods can be applied, including machining or net shape forming to produce a wide variety of sizes and shapes of components.

Alumina Rod uses

The combination of key properties that Alumina Tubes and Rods offer makes them a cost-effective yet high-performance solution that can be used in a wide variety of applications across numerous industries. Alumina is widely used as an electrically insulating material, especially is environments operating at elevated temperatures such as furnace lead-in tubes, heat treating furnace rollers, radiant tubes, laser tubes, etc. Alumina Rods are also a very popular man-made choice for imparting durable, smooth-cutting edges on household tools. As an abrasive it is highly effective, and it is a less-expensive substitute for industrial Diamond.

When it comes to art and design, the material can be used for heating elements for different types of appliances such as ceramic pottery and pottery art. Alumina Rod’s aesthetic also lends itself to conceptual design pieces with its industrial look.
