Highest strength and hardness within our marine suite of alloys, with tensile strengths over 1000MPa possible.

This elite marine alloy has high strength and hardness combined with high toughness and good ductility.

High strength is combined with extremely high toughness and good ductility together with outstanding seawater corrosion resistance.

Our corrosion resistant alloys are strengthened by both solid solution and precipitation mechanisms. Our deep metallurgical understanding and direct control of processing gives us the capability to induce material properties that are unavailable elsewhere.
This suite of elite marine alloys has a wide spectrum of mechanical properties ensuring a range of demanding applications can be satisfied. Our corrosion resistant alloys are also available in extreme fracture toughness combined with high strength, through to extreme tensile strength and hardness.
The extremely low general corrosion rate and immunity to preferential phase attack make these materials ideal for critical marine applications and out-perform conventional materials such as nickel aluminium bronze and conventional cupro-nickel alloys by far.
These industry-leading alloys are the result of decades of research and our advanced manufacturing capability combined with metallurgical expertise, allowing us to produce a range of wrought products to 5 Tonnes piece-weight.
These materials are available as raw material (proof machined bar stock, forgings, plates) or finished machined components.
Full traceability and full certification in accordance with EN 10204 3.1 are provided as standard. 3.2 Certification is available upon request.
