Molymet has announced the creation of Molymet Alloys in the USA, marking its first industrial investment in the country (US$40M). The new subsidiary will enable the company to develop a line of higher-value products for the US market, a key hub for aerospace, defence, energy, medical and semiconductor industries.

The establishment of Molymet Alloys was achieved through the acquisition of Rhenium Alloys, located near Cleveland, Ohio. Rhenium Alloys specialises in producing finished and semi-finished molybdenum, tungsten, and rhenium products for high-performance technologies.

The move advances Molymet along the value chain, adds tungsten to its portfolio, and brings specialised expertise in alloys and industrial components for demanding sectors. It allows the company to offer higher-value products with improved margins.

This milestone is particularly notable for the rhenium market. Rhenium, a critical metal used in nickel-based superalloys for high-temperature applications and medical applications, now benefits from an expanded production and processing base in the USA. This strengthens domestic access for industries reliant on high-purity rhenium products and enhances supply security for key sectors including aerospace, defence and high-tech manufacturing.

By adding Rhenium Alloys to its US operations, Molymet reinforces the country’s capacity to produce and process high-temperature materials locally. This move supports superalloy manufacturers seeking to reduce import dependencies. It also provides commercial and military jet engine original equipment manufacturers (OEMs) with more stable, onshore sources of rhenium, improving upstream input security and supporting production resilience and risk mitigation.

While this step will not eliminate all US dependency on foreign supply chains, it marks meaningful progress towards a more resilient domestic superalloy ecosystem. It aligns closely with the broader US industrial strategy to localise critical mineral processing, strengthen high-temperature materials capability and safeguard national aerospace and defence production against future supply disruptions.
