Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| High alloy heat resistant steel plates | Alumina withstands working temperatures up to 1800°C without softening, but lacks the tensile flexibility and impact resilience of steel |
| Standard industrial polymer plates | Alumina provides superior wear resistance and chemical stability at extreme heat, but requires diamond tooling to machine once sintered |
| Off-the-shelf catalog ceramic tiles | Custom alumina plates are manufactured to exact drawing dimensions up to 850 mm diameter, avoiding layout compromises but requiring production lead time |
Use Guide
- Provide technical drawings showing target diameter between 10 and 850 mm and thickness between 7 and 40 mm
- Define the maximum continuous operating temperature to select the correct purity between 92% and 99.7%
- State chemical media exposure details, specifically contact with concentrated acids or alkalis
- Ensure mounting assemblies account for mechanical hardness and low thermal expansion characteristics
- Specify preferred protective export packaging such as padded wooden crates to prevent transit shock
