Lead Alloy Castings

NW Precision Finishing Ltd has been delivering precision-engineered Lead Alloy Castings for over a decade. Our in-house expertise supports the production of high-quality lead components for some of the world’s leading manufacturers in sectors such as defence (including submarine applications), power transmission, and battery and connector technologies.

Our skilled team specialises in casting, burning, and welding lead alloys to meet exact customer specifications, delivering consistency, safety, and performance in every component we produce.

We also have the capacity to produce lead ballast tailored for offshore, marine, and industrial applications, offering weight solutions with durability and corrosion resistance where it matters most.

We are proud to work in partnership with THOR Hammer, supplying precision-cast mallets and hammer heads that meet the highest standards of quality and durability for industrial and specialist use.

With in-house CAD design and CNC machining capabilities, we offer complete mould design and manufacturing services. This enables us to quickly develop and refine tooling for custom lead castings, ensuring rapid turnaround, consistent quality, and full control from concept to production.

In addition to industrial manufacturing, we have supported restoration projects by recreating historically accurate parts — including lead balance weights for WW2-era aircraft — helping preserve vital pieces of aviation history with precision and care.
