Oxford Sigma tackles energy security and climate change by accelerating the development of fusion and advanced nuclear energy.
The company aims to develop enabling materials technologies in fusion energy, develop materials for extreme environments, and provides design services to accelerate and achieve commercialisation.
Oxford Sigma specialises in the following sectors:

Materials for Extreme Environments
Oxford Sigma’s team are experts in materials for extreme environments, which include high temperatures, extreme radiation damage, and highly corrosive environments (such as liquid metals, molten salts and gases). We design our own materials technologies that withstand these conditions. The image shows an electron backscatter diffraction pole map of Oxide Dispersion Strengthened Steel by Oxford Sigma.
