Awekeys prioritizes sustainability and strives to minimize our environmental impact. We have been researching the material for metal keycaps for several months in the beginning of the project. We found that cupronickel is a commonly used material for currency coins for its durability, low allergic risk and recyclability. The production of recycled cupronickel keycaps requires significantly less energy compared to producing metal from virgin materials. This not only conserves natural resources and reduces energy consumption but also lowers carbon emissions, and promote a circular economy.
