Notes
- Currently, it takes at least 597 Beryllium Copper to complete its uses.
- In its real-world applications, beryllium is usually alloyed with copper to remove more dangerous properties from a purer form of the latter, most notably its ease of sparking and high magnetism. Doing so also increases the overall strength of the material, making it ideal for items that must keep their shape over time.
