S-200-F H Beryllium: High-Performance Structural Grade

Hot isostatically pressed structural grade 98.5% beryllium. This beryllium is more uniform with higher density and higher mechanical properties than traditional vacuum hot pressed beryllium. The material can be formed into regular or custom shapes, and the production process has been optimized to conserve material and reduce total machining time.
