Core Advantages Of Alumina Ceramic Ring
Экстремальная устойчивость к окружающей среде
Высокая температура & сопротивление ползучести: Стабилен до 1200°C, низкое тепловое расширение (7.2×10⁻⁶/°С), no deformation at high temperature. Suitable for melting furnaces and sintering kiln components.
Полная химическая инертность: Resists HCl, ВЧ (<5% F⁻), molten salt corrosion; срок службы >10× that of metal rings.
Precision Motion & Sealing
Ultra-low friction: Mirror-polished surface, коэффициент трения <0.1, reduces energy consumption, suitable for high-speed bearings (>10,000rpm).
Zero-leak sealing: Flatness ±0.002mm, sealing contact >99%, сопротивление давлению ≥50 МПа, ideal for ultra-high pressure pump & valve seals.
Multi‑functional Adaptability
Изоляция & теплопроводность: Dielectric strength ≥20kV/mm, thermal conductivity 30W/m・K, suitable for semiconductor insulation rings and laser heat sinks.
Легкий дизайн: Density 3.9g/cm³, 1/3 the weight of stainless steel, reduces inertia load in high-speed equipment.
