(NING YOUPENG)

Ni Fei, a research and development staff member at a company in Jimo, east China's Shandong Province, examines amorphous ribbons on July 9.

An amorphous ribbon is a thin foil widely used in electricity, electronics, aeronautics and astronautics.

The fifth-generation super-thin amorphous ribbon was invented in Jimo and has broken the Japanese monopoly on the sector. The city produces 3,000 tons of amorphous ribbon every year.
