Problems solved by technology

[0004] However, at present, because beryllium is expensive and highly toxic, the content of existing beryllium is usually more than 0.5%, which has hidden dangers affecting human and environmental safety.
In addition, the existing beryllium-containing copper alloys still have room for improvement in terms of temperature resistance and stability
