  • Extreme mechanical strength
  • Low rate of general corrosion and pitting in sea-water
  • High hardness and resistance to wear
  • Very high shock resistance
  • Low relative magnetic permeability
  • Anti bio-fouling (lack of marine growth)
  • Immune to hydrogen embrittlement
  • Anti-galling
  • Easy to machine and dimensionally stable
  • No loss of properties at cryogenic temperatures
  • Cost-effective compared with other materials


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.
