Hluru's copper-infused steel is created using a special process that involves adding copper ions during the smelting process. This enhances the steel's corrosion resistance, antibacterial properties, strength, and vibrational performance. Through a process called aging heat treatment, the copper ions bond more deeply with the steel, giving the material a tone that resonates more like copper.
The resulting sound is rich in overtones, creating a layered and complex tone. The mid and low frequencies are particularly prominent. This makes it ideal for those who prefer a heavy, deep bass, short sustain, a crisp sound, and a wide range of playing styles. It's perfect for fast-paced tapping and chord-heavy polyrhythmic compositions.
