Domel’s response to global copper price pressures
Volatility in raw material markets—especially copper—has become a major challenge for manufacturers, impacting costs, supply chains, and long-term planning. At Domel, we treat this not as a constraint, but as an engineering opportunity.
Engineering for cost resilience
To address price instability, Domel has implemented advanced design optimisations for vacuum motors :
- replacement of copper windings with aluminium,
- reduction in electrical steel usage,
- optimisation of motor architecture.
This enables lower material costs while maintaining Domel’s high standards of performance and reliability.
Market context: copper vs aluminium
Recent trends show a clear divergence:
- copper prices remain highly volatile, with a sharp increase in early 2026,
- aluminium prices are more stable, with gradual growth.
This strengthens the case for strategic material substitution.

Measured benefits
Our approach delivers tangible results:
- 15% reduction in electrical steel,
- 50% reduction in copper usage,
- 15% lower product mass,
- preservation of performance characteristics and long-term reliability.
Testing confirms that aluminium windings achieve equivalent performance to copper-based designs.
Looking ahead
Raw material volatility will remain a key challenge. Domel continues to focus on engineering innovation and smart material optimisation to deliver high-performance solutions without compromise.
In today’s environment, cost resilience is not just an advantage—it is essential.
