its exceptional properties
Alumina ceramic substrate Information:

Performance parameters:

Properties of Alumina Ceramic parts:

1.High Electrical Insulation: Room temperature resistivity >10¹⁴ Ω·cm, with dielectric strength of 15–20 kV/mm, effectively preventing
current leakage and short circuits .

2.Excellent Thermal Conductivity: Ranges from 18–35 W/(m·K) depending on purity (92%–99.7%), efficiently dissipating heat generated
during high-power charging .

3.Thermal Stability: Withstands long-term operation at temperatures up to 1600°C (melting point 2050°C), ensuring reliability under thermal
cycling .

4.Mechanical Strength: High hardness (HV 15–20 GPa) and flexural strength (300–370 MPa) provide structural integrity and resistance to
mechanical stress.

5.Chemical Inertness: Resists corrosion from coolants, oils, and environmental exposure, enhancing durability in harsh conditions .

Applications of Alumina Ceramic part:

In new energy charging stations, alumina ceramic bases serve critical functions:

• IGBT Insulation and Heat Dissipation: Used as insulating layers between IGBT modules and heat sinks in high-voltage charging piles.
  For example, ceramic sheets with metal inserts are designed to enhance dielectric strength while maintaining thermal transfer efficiency .

• Thermal Management for High-Power Systems: Essential for DC fast chargers (e.g., 350 kW+), where temperatures exceed 150°C. Alumina
  bases dissipate heat from power electronics, preventing overheating and ensuring safety .

• Fire Safety and Isolation: Ceramic aerogel insulation plates (e.g., Al₂O₃-based) are integrated into battery swap cabinets to block heat transfer
  between charging compartments, reducing fire risks .

Customization and Quality Assurance

• Customization: Many manufacturers offer alumina plates tailored to specific dimensions, shapes, and performance requirements
  based on customer drawings or samples.

• Quality Control: Manufacturers adhere to strict quality control processes, including ISO certifications, to ensure the plates meet
  high standards of durability and performance
