 Materials for use in vacuum

Materials used in vacuum applications are specifically chosen for their ability to maintain their properties under low-pressure conditions, resist outgassing, and maintain structural integrity. Here are key categories and examples of materials suitable for use in vacuum environments: ### Metals 1. **Stainless Steel**: Resistant to corrosion and has good strength, often used for vacuum chambers and components. 2. **Aluminum**: Lightweight and has good thermal and electrical conductivity; often used in vacuum systems where weight savings are critical.
