Key Features And Applications of CIM-Al2O3 Parts


Ceramic Injection Molding (CIM) Alumina (Al2O3) parts typically exhibit a hardness ranging from 80 to 90 HRA (Rockwell hardness scale). This high hardness level is a result of the intrinsic properties of alumina, making CIM-Al2O3 parts exceptionally resistant to wear and abrasion. This attribute is precious in applications where components experience friction, impact, or contact with abrasive materials.

Alumina (Al2O3) CIM parts find applications in industries requiring hardness properties, such as cutting tools and wear-resistant components. In cutting tools, the hardness of CIM-Al2O3 allows them to withstand the mechanical stress and friction generated during the machining process. Similarly, wear-resistant components benefit from the hardness of alumina by maintaining their integrity and performance even in abrasive environments.

The hardness of CIM-Al2O3 parts also makes them resistant to corrosion. This makes them suitable for applications where they will be exposed to chemicals or other corrosive environments.


Thermal Conductivity

Ceramic Injection Molding (CIM) Alumina (Al2O3) parts typically exhibit a high thermal conductivity, ranging from 20 to 35 W/m·K. This remarkable thermal conductivity stems from the crystalline structure of alumina, enabling efficient heat transfer.

Alumina (Al2O3) CIM parts find essential applications in industries requiring superior thermal conductivity properties. In electronics, CIM-Al2O3 heat sinks efficiently dissipate heat generated by electronic components, ensuring optimal device performance and longevity. Industrial processes, like those involving metal casting, benefit from alumina's ability to regulate temperature, enhancing process control.

Additionally, CIM-Al2O3 parts in high-temperature environments, such as gas turbine engine components, rely on thermal conductivity to withstand and manage extreme temperatures effectively.


Ceramic Injection Molding (CIM) Alumina (Al2O3) parts exhibit impressive strength characteristics, with typical flexural strengths ranging from 300 to 400 MPa. This strength results from the dense and uniform microstructure of alumina, which provides excellent resistance to applied forces and mechanical stresses. CIM-Al2O3 parts' strength makes them suitable for applications demanding durability, load-bearing capacity, and resistance to deformation under pressure or impact.

Alumina (Al2O3) CIM parts find crucial applications in industries that require robust strength properties. In the automotive sector, CIM-Al2O3 parts serve as components in engines and transmissions, where they endure mechanical forces and thermal cycles. Similarly, industrial machinery benefits from alumina's strength, with parts like ceramic bearings and cutting tools maintaining their integrity under high loads.

The strength of CIM-Al2O3 parts also makes them resistant to fatigue. This makes them suitable for applications where they will be subjected to repeated loading and unloading.


Chemical Inertness

Ceramic Injection Molding (CIM) Alumina (Al2O3) parts possess exceptional chemical inertness, exhibiting resistance to chemical reactions with most substances. This property is attributed to the stable crystalline structure of alumina, which makes CIM-Al2O3 parts suitable for applications in corrosive and reactive environments where chemical stability is paramount. The chemical inertness ensures minimal interaction with acids, bases, and other corrosive agents, contributing to the longevity and reliability of CIM-Al2O3 parts.
