IN Brief:
- Castings Technology has secured £9m in defence work for titanium structures linked to UK-based artillery supply-chain activity.
- The company is expanding with an approximately 200,000 sq ft Sheffield facility and new high-value melting and heat-treatment equipment.
- The opportunity is strategic, but titanium remains a difficult market defined by process complexity, limited capacity, and upstream material dependence.
Castings Technology has secured £9m in defence contracts for titanium structures, adding fresh momentum to one of the UK’s more specialised advanced-manufacturing niches. The work is understood to support production tied to the M777 lightweight howitzer supply chain, as Britain takes on a larger role in major structure manufacture that had previously been handled in the United States.
For the defence sector, the significance lies well beyond the contract value. Structural titanium capacity is rare, qualification-heavy, and slow to recreate, which means even comparatively modest orders can have outsized strategic importance. Castings Technology has said the new work includes repeat business as well as new components, with some parts reaching up to two metres in length and requiring complex casting methods.
That complexity is precisely why the business has won attention. Castings Technology describes itself as the UK’s only commercial titanium castings facility and one of a small number of global producers working at this level. On the company’s own account, it can produce titanium castings from 0.1kg to 400kg, with proof and finish machining, radiography, ultrasonic inspection, dye-penetrant testing, metrology, and metallurgical capability on site. In defence manufacturing, that degree of vertical control matters because supply assurance is only credible when inspection and process knowledge travel with the part.
The contract timing also aligns with the company’s site expansion. Castings Technology is investing £18m in a new Sheffield facility of roughly 200,000 sq ft, expected to be operational in the second half of 2026. The move includes major process equipment such as a new vacuum arc remelting furnace and heat-treatment furnace, both of which point to a business scaling around demanding metalworking rather than generic foundry volume.
Titanium capacity is hard to recreate
Titanium keeps appearing in defence programmes for a simple reason: it solves difficult design problems. It offers a strong strength-to-weight ratio, corrosion resistance, and good fatigue performance, which is why it remains attractive for artillery structures, aerospace assemblies, naval applications, and other weight-sensitive systems. Castings Technology says its near-net-shape processes can deliver mechanical performance equivalent to wrought or forged material, while keeping the manufacturing route competitive for complex geometries.
That does not make titanium easy. Reactive melting, controlled atmospheres, mould design, thermal treatment, and non-destructive testing all have to line up. The barrier to entry is high, which is why reshoring this sort of work cannot be improvised once demand spikes.
Reshoring still starts with raw materials
There is also a harder reality behind the good news. Sovereign finishing capability does not automatically equal sovereign material supply. Titanium feedstock still depends on long, internationally exposed supply chains, and those upstream dependencies can undercut the value of domestic processing if procurement is left too late.
Even so, contracts like this matter because they help keep the downstream capability alive and growing. If the UK wants serious resilience in artillery, aerospace, and future land systems, it needs foundries and process specialists that can handle large, high-integrity structures when programmes move from rhetoric to metal. Castings Technology is now much more clearly in that category.
