Forged Parts

Allship Engineering supplies precision marine forgings through its partnership with Zollern, a global copper and copper-alloy forging specialist. The forging process creates a uniform material structure with minimal internal stresses and defects, making forged parts suitable for high-load, high-pressure marine environments. Forged parts deliver reliability across propulsion, drivetrain, structural and fluid-handling components. 

Zollern produces preliminary materials in-house and has wide capabilities, including open die forging, drop forging and ring rolling capabilities. This enables Allship Engineering to supply precision marine forgings in small batches or large production runs with shortened lead times.

What Marine Forged Parts Can Allship Provide?

Allship Engineering provides custom forgings for specific marine applications, replacement forged components for repairs and refits, at any production run size through its partnership with Zollern.

Forging shapes metal under high pressure, producing components with enhanced grain structure and fatigue resistance. The process delivers strong, reliable and corrosion-resistant parts for marine use.

  • Available products include:
  • Seamless rings
  • Shafts
  • Bars
  • Bushings
  • Custom-shaped components for specific applications

Available materials include a broad range of copper and copper-alloy materials: copper-aluminium, copper-nickel, copper-zinc, copper-chrome-zirconium, copper-nickel-silicon and pure copper. Parts are manufactured to DIN, EN, ASTM, ASME, AMS, MIL and Def Stan specifications.

Benefits of Marine Forged Parts

Purpose-Built for Marine Conditions
Forged parts have a uniform, refined material structure with low internal stresses. This produces components with fatigue resistance, deformation resistance, and impact resistance suited to drive systems, propulsion, high-load shafts, and safety-critical assemblies.
Low Defect Risk and High Integrity
Forging reduces internal voids and inclusions compared to other manufacturing methods. This results in lower warpage during machining and consistent performance in high-pressure marine systems.
Design Flexibility Across Copper Alloys
Available alloy families include copper-aluminium, copper-nickel, copper-chrome-zirconium, copper-zinc, copper-nickel-silicon, pure copper, and customer-specific alloys with enhanced strength characteristics. These materials provide corrosion resistance, weldability, and heat resistance for seawater systems and marine environments.
Quality Assurance and Testing
Allship provides NDT testing (PT/UT/MT), tensile testing, impact testing, hardness testing, electrical conductivity testing, and metallographic examination for grain size and microstructure evaluation. All components meet DIN, EN, ASTM, MIL, and other global marine and industrial standards.

Forging Processes

Open Die Forging

Open die forging is ideal for large, heavy and custom-shaped marine components. The process delivers high strength and structural integrity for unique specifications.

Ring Rolling

Ring rolling produces seamless rolled rings for propulsion systems, bearings and rotating assemblies.

Drop Forging
Drop forging creates precision-shaped fittings, connectors, and repeated production of smaller marine components.
Seamlessly Forged Bushings and Shafts
Seamless forging produces bushings and shafts for high-load marine mechanisms. These components provide reliability and dimensional stability.
Forged Bars and Semi-Finished Products
Forged bars and semi-finished products serve as stock material for machining into marine components as needed.

Maritime Applications

Allship Engineering supplies forged components for ships and naval vessels across multiple system types.

Common forged components include:

  • Shafts and shaft-line components
  • Propulsion system elements
  • Bushings and bearing rings
  • High-load structural components
  • Valve and pump components
  • Flanges, couplings and pressure-resistant connectors
  • Forged rings for propulsion or rotating systems
  • Components for cooling systems and thermal management systems

Forged parts offer enhanced strength, low defect rates and long service life in ocean environments.

Alloy Groups for Marine Forgings

Allship Engineering supplies forged components in multiple copper and copper-alloy groups suited to marine environments.

Available alloy groups include:

  • Copper-aluminium
  • Copper-nickel
  • Copper-zinc
  • Copper-chrome-zirconium
  • Copper-nickel-silicon
  • Pure copper
  • Special copper-based alloys for enhanced strength or corrosion resistance

These materials offer corrosion resistance, weldability, heat resistance and performance in seawater systems. Copper-nickel alloys are particularly suited to seawater applications.
