See below for more detailed information:

Material: Ceramic alumina socket head screws are primarily manufactured from alumina ceramic, which is a polycrystalline material with high hardness and strength. Alumina ceramics have exceptional wear resistance, high temperature tolerance (up to 1,500°C) and chemical stability.

Manufactured to DIN 912: All socket head screws available through High Performance Polymer are manufactured to DIN 912 standards, ensuring standardisation is met across our range.

High Temperature Resistance: Alumina ceramic exhibits excellent resistance to high temperatures (up to 1,500°C continuous). It can withstand extreme heat without significant deformation or loss of mechanical properties. This makes ceramic alumina socket head screws suitable for applications in high-temperature environments, such as satellites, vacuum furnaces and within the Oil and Gas industry.

Exceptional Hardness: Alumina ceramic is known for its high hardness, ranking just below diamond on the Mohs scale. Ceramic alumina socket head screws offer exceptional resistance to abrasion, wear, and surface damage. This makes them ideal for applications where components are subjected to friction or abrasive forces.

Corrosion Resistance: Alumina ceramic is highly resistant to corrosion and chemical attack. It can withstand exposure to various acids, alkalis, and corrosive substances without degradation. Ceramic alumina socket head screws are commonly used in corrosive environments or industries where chemical resistance is essential, such as chemical processing plants.

Electrical Insulation: Alumina ceramic is an excellent electrical insulator. Ceramic alumina socket head screws do not conduct electricity, making them suitable for applications where electrical insulation is necessary, such as in electronic devices or high-voltage equipment.

Lightweight: Compared to metallic nuts, ceramic alumina socket head screws are lightweight. This property is advantageous in applications where weight reduction is a priority, such as aerospace or automotive industries, where minimizing the overall weight of the components is crucial for fuel efficiency and performance.

Specialized Applications: Ceramic alumina socket head screws are design for applications in a wide range of industries, including aerospace, automotive, electronics, semiconductor manufacturing, chemical processing, and high-temperature equipment. They are commonly used in environments where their unique combination of properties, including high temperature resistance, hardness, corrosion resistance, and electrical insulation, is advantageous.
