Global Demand for Oxygen-Free Copper Drives Innovation in Casting Technology

Global demand for oxygen-free copper continues to climb, driven by electrification, renewable energy infrastructure and high-performance electronics. For producers, the challenge is meeting that demand without sacrificing the purity and surface quality these applications require.

Continuous casting has emerged as a key enabling technology. By integrating melting and casting within a sealed, inert environment, oxygen pickup is held to parts-per-million levels — preserving the conductivity that makes oxygen-free copper so valuable.

Scaling without compromise

Rautomead’s upward casting systems are designed to scale from boutique output through to many thousands of tonnes per year, giving manufacturers a clear path to grow capacity while maintaining tight control over quality and yield.

As the market matures, the emphasis is shifting from raw volume to repeatable, certifiable quality — an area where continuous casting offers a decisive advantage.
