High energy at your fingertips! Rotosound's new Ultramag strings are made with type 52 alloy – a highly magnetic material made from 52% nickel and 48% iron. This blend gives Ultramag strings more power, sustain, and a longer string life than traditional nickel or steel strings.

Ultramag strings deliver a strong output with pronounced mid and low frequencies – perfect for powerful baselines and driving riffs.

Rotosound use type 52 alloy designed for use in the aerospace industry allowing Ultramag strings to maintain their tuning in the most extreme environments.

To top this all off, type 52 alloy has corrosion resistant properties so your great tone keeps going for longer.

This innovation continues Rotosound’s proud legacy of cutting-edge string design that started with our roundwound strings in the sixties.
