Cermet Inserts
- Cermet Inserts
A cermet is a composite material combining ceramic and metal components. It's essentially a blend of ceramic (cer) and metal (met) materials. Cermets are often used in applications requiring high wear and temperature resistance, as well as in situations where neither ceramic nor metal alone would suffice.
Cermet is commonly used to cut various metals, including carbon and alloy steels, stainless steels, and high-temperature alloys. It's also suitable for finishing and semifinishing operations on these materials.
Cermets are not typically used to cut cast iron or aluminum.
Key Characteristics and Uses:
Composition:
Cermets typically consist of ceramic particles, such as titanium carbide (TiC) or titanium nitride (TiN), bonded by a metal matrix.
Properties:
They offer a combination of hardness and toughness, as well as resistance to high temperatures, wear, and corrosion.
Applications:
Cutting tools: Cermets are used in cutting tools like drill bits, saw blades, and milling cutters for their high wear resistance.
Electronic components: They are used in resistors, capacitors, and other electronic components that may be exposed to high temperatures.
Brazed instruments: They are used instead of tungsten carbide in saws and other brazed instruments due to their improved wear and corrosion resistance.
Spacecraft shielding: Some cermets are being considered for use in spacecraft shielding due to their ability to resist micrometeoroid impacts.
Dental cermets: Used in dentistry as a material for fillings and prostheses.
