Mitsubishi Materials’ alloy development technology is utilized in many objects we interact with on a daily basis. One such example is the copper alloy CLEANBRIGHT®, which leverages the antibacterial and antiviral properties of copper. It is used for hospital door handles, handrails, and more. Furthermore, this new copper alloy maintains  its beautiful champagne gold color for a long period of time.

CLEANBRIGHT® is a copper alloy with long-lasting antibacterial and antiviral effects. These effects are attributed to copper’s ability to rapidly destroy bacteria and viruses. Additionally, CLEANBRIGHT®, with its ease of processing, is well-suited for manufacturing items like door handles and handrails that are frequently touched in our daily lives, making it a valuable choice for scenarios where antibacterial properties are desired.

The unique feature of CLEANBRIGHT® is that it has better resistance to discoloration compared to conventional copper alloys. Copper tends to discolor due to factors like the oxygen in the air and the moisture on people’s hands. However, Mitsubishi Materials has solved this issue using its know-how and advanced evaluation techniques cultivated through years of alloy development. We have successfully developed an alloy that is less prone to color irregularities caused by discoloration. Even after long-term use, such as 5 or 10 years, there is no noticeable change. The original sophisticated and beautiful color and shine of champagne gold will remain for a long time!
