Ceramic parts are usually used in wire processing and galvanic wire plating as wire guides and pulleys.
Ceramic parts show many advantages in comparison to the parts made of steel or tungsten carbide. The friction and the wear between the sliding material and the ceramic guide are minimized due to very high hardness and optimized slide surfaces of ceramic parts.
Cold welding between ceramics and wire is not possible. The very high electric resistivity of ceramic parts avoids static charge.
The parts are made from alumina, zirconia or silicon nitride.

Alumina ceramic, also known as aluminum oxide ceramic, is a high-performance material widely used in industrial and technical applications due to its excellent mechanical, thermal, and electrical properties.
Composition and Structure
Alumina ceramic is primarily composed of aluminum oxide (Al₂O₃), with purity levels ranging from 85% to 99.9%. Higher purity alumina exhibits superior hardness, corrosion resistance, and dielectric strength.

Key Properties

• High Hardness: Alumina ceramic is extremely hard, making it resistant to wear and abrasion.
• Thermal Stability: It maintains strength and stability at high temperatures (up to 1600°C).
• Electrical Insulation: Excellent dielectric properties, making it suitable for electronic applications.
• Chemical Resistance:Resistant to acids, alkalis, and corrosive environments.
• Mechanical Strength:High compressive strength but relatively brittle compared to metals.

Applications

• Electronics: Substrates, insulators, and components in semiconductors.
• Industrial Wear Parts:Cutting tools, seals, and bearings.
• Medical: Biocompatible implants and surgical tools.
• High-Temperature Environments: Furnace linings and thermocouple tubes.
• Defense & Aerospace: Armor plating and heat-resistant components.
