Copper is widely recognized for its exceptional electrical and thermal conductivity, but its value extends far beyond power transmission. It plays a critical role across construction, transportation, electronics manufacturing, and numerous hightechnology industries.
Highpurity copper—along with its alloys and compounds—is essential for advanced thinfilm fabrication. It is commonly used as an evaporation material to deposit highquality thin films in the production of semiconductor devices, sensors, and integrated circuit components.
In the medical field, highpurity copper is a key material in the manufacture of superconducting MRI magnets, where purity and performance directly influence magnetic stability and imaging precision.
Copper is also a primary material for sputtering targets, which are indispensable in semiconductor processing and flatpanel display manufacturing. In addition, it serves as a source material for molecular beam epitaxy (MBE), supporting both cuttingedge semiconductor research and commercial device production where precise control of film composition and purity is critical.
