How to Select the Right Material Grade?

1. Environmental Compatibility: Match material grade to chemical exposure (acid/alkali concentration, temperature).
2. Thermal Requirements: Opt for Ta-W alloys (e.g., Ta10W) for high-temperature strength and creep resistance.
3. Dimensional Precision: Specify thickness, width, and tolerance (±0.02 mm achievable).
4. Surface Treatment: Choose polishing, anodization, or coatings to enhance performance.
