Product Description
High Hardness Machining Polished Silicon Carbide SiC Ceramic Washer
Silicon Carbide Ceramic
Silicon Carbide (SiC) is one of the lightest, hardest, advanced ceramic materials and has exceptional thermal conductivity with resistance to temperature / acids, and has a low thermal expansion. Silicon Carbide is an excellent material to use when wear is an important consideration because it exhibits good sliding, erosion and abrasive resistance, making it useful in a variety of applications such as seal rings, nozzles, and hydro cyclone components. Silicon carbide materials are electrically conductive and this may be helpful for resistive or inductive heating, dissipating charge etc.
Silicon Carbide (SiC) Washers are high-performance precision ceramic flat washers and sealing gaskets tailored for extreme industrial working conditions. Fabricated from high-purity silicon carbide raw materials through professional sintering processes and ultra-precision grinding and polishing, these SiC washers feature uniform density, flawless flat surface and outstanding mechanical stability. As an upgraded alternative to traditional metal, rubber and ordinary ceramic washers, they effectively solve common industrial problems such as abrasive wear, chemical corrosion, high-temperature aging and pressure deformation, delivering reliable sealing, spacing and anti-wear protection for mechanical equipment.
Characteristics:
Silicon carbide ceramic stands out among industrial structural materials with its unique comprehensive performance, making our bushing sleeves suitable for harsh working scenarios that most conventional materials cannot withstand:
SiC ceramic washers integrate superior mechanical, chemical and thermal properties, making them ideal for harsh working environments where conventional gaskets fail to work stably:
-
Excellent Chemical Corrosion Resistance: Featuring excellent chemical inertness, SiC washers are resistant to most strong acids, alkalis, organic solvents and corrosive slurries. They will not rust, oxidize, swell or degrade in corrosive mediums, ensuring long-term stable sealing performance in chemical, environmental protection and petrochemical scenarios.
- Extreme High Temperature Resistance: Capable of continuous operation at high temperatures up to 1600°C, with an extremely low thermal expansion coefficient. The washers will not deform, soften or crack under high-temperature and high-pressure conditions, maintaining precise spacing and tight sealing for high-temperature equipment assemblies.
-
Precision Flatness & Tight Sealing: Processed by fine surface grinding and mirror polishing, the product features ultra-smooth surface and high flatness tolerance. It fits closely with matching parts without gaps, providing excellent static and dynamic sealing effects, effectively preventing medium leakage and equipment loosening.
- High Pressure & Impact Resistance: With high compressive strength and structural toughness, SiC washers can withstand strong extrusion and mechanical impact, avoiding cracking and deformation under high-pressure operating conditions, adapting to high-load industrial equipment operation.
-
Oil-Free Self-Lubrication & Long Service Life: Possessing natural self-lubricating performance, the washers require no lubricating oil during operation, suitable for high-cleanliness, dust-free and oil-free working environments. Their service life is 8–15 times longer than traditional metal gaskets, greatly reducing replacement frequency and equipment maintenance costs.
