The description of alumina ceramic parts
Aluminum oxide (Alumina) has extensive application due to its versatility and low material cost than other advanced ceramics. Alumina offers high electrical insulation resistance, high-temperature resistance, strong hardness, wear resistance, and good chemical stability, making it a good material to withstand high temperatures and chemical corrosion.

Our factory produces a selection of alumina purity from 75% to 99.8%, all of the ceramic parts we supply have a dense body via dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To achieve special applications for fitting, reducing friction, and increasing the insulation, we provide a series of secondary processes after sintering, covering CNC machining, polishing, glazing, and metalizing.

We manufacture numerous alumina ceramic components, including ceramic tubes, rings, discs, rods, arms, and wire guides. Whether it's a prototyping case or high-volume demand, we believe we can provide you with a desirable solution.
