Introducing everything from ultra-high purity 99.99% to cost-reduced 99% alumina.

A wide range of products from 99.99% alumina that meets strict purity requirements to 99% overseas alumina that ensures cost reduction.

We offer various grades of alumina ceramics at our company. - High purity 99.99% - High purity 99.99% translucent - Purity 99.0% - Purity 99.5% alumina for machining, available in sizes up to Φ600 - Purity 99.5% alumina for machining with short delivery times - Purity 99% overseas alumina, suitable for cost-effective mass production, also compatible with pure water washing - Sapphire In the semiconductor/display manufacturing equipment sector, various specification requirements are demanded. There are numerous grades of alumina, ranging from high-purity high-end products to cost-focused alumina that requires insulation properties and mechanical characteristics with only a certain level of high purity. We can meet all such diverse alumina requirements. While large items over one meter fall under the domain of specialized manufacturers, we have alumina for machining in stock up to Φ600, allowing us to provide according to requested delivery times. We respond to various needs with one-stop solutions, from pure water washing to semiconductor-grade precision cleaning, mirror finishes, and hand wrapping. Please feel free to consult with us first.

Which is better, alumina or steatite?

Which is better, alumina or steatite?

We will provide proposals and consultations on all aspects, including price and delivery time.

[For those who think, "Ceramics are expensive because they are ceramics!"] *Characteristics of two types of ceramic materials: Alumina: High mechanical strength with resistance to corrosion and wear, but more expensive than steatite (about 1.5 times). Steatite: Good insulation properties and inexpensive. Commonly used in electrical and heating components. [Common examples] If a part designed for insulation can be sufficiently made from steatite, making it from alumina will naturally increase the cost. If a part is made from steatite for wear resistance simply because it is cheaper, it will wear out quickly, resulting in the need to produce more parts, ultimately increasing costs. *Choosing the right ceramic material based on application is the key to purchasing at a lower cost.

The most versatile ceramic is "alumina (Al₂O₃)."

The most versatile ceramic is "alumina (Al₂O₃)."

A representative material of ceramic that is highly versatile and relatively inexpensive.

Alumina refers to aluminum oxide. Due to its high versatility and relatively low cost, it is the most commonly used representative material among ceramics. It has high electrical insulation properties and excels in hardness, compressive strength, wear resistance, and chemical resistance, making it widely used as a mechanical material. Our company primarily uses 99.5% alumina, but we also offer 96% depending on the application. Metallization processing is also possible for alumina substrates. Please contact us for more details. <Features> - A highly versatile material among ceramics - Widely used as a mechanical material due to its excellent hardness, compressive strength, wear resistance, and chemical resistance - High electrical insulation properties and relatively low cost - High heat resistance (approximately 1500°C) and relatively high thermal conductivity. However, it has a high thermal expansion coefficient and is weak against thermal shock.
