Where low weight and
high mechanical demands meet.
EURAD has developed and supplied certified cast aluminium products for over 35 years — for applications where low weight, fatigue resistance and certified material properties must perform together under demanding operating conditions. From certified aluminium reducers and adapters for marine loading arms and tanker manifold connections, to engineered wheel cores used in rollercoasters at major theme parks — both applications demand long-term mechanical reliability and maximum safety.
Engineered aluminium
for critical applications
EURAD’s cast aluminium division was established from a clear industrial need: applications where existing aluminium alloys could not meet the combined requirements of elongation, pressure resistance and cyclic fatigue performance. Within that context, EURAD developed the E39 alloy, applied notably in wheel cores for attractions certified under EN 13814 (TÜV-certified).
Since 1991, EURAD’s cast aluminium spool pieces have held design approval from the Dienst voor het Stoomwezen — the former Dutch sovereign authority for pressure equipment — with stamps on all technical dimension tables. A design and quality continuity spanning multiple decades.
Every EURAD aluminium product is supplied with certified material properties and full test documentation — ensuring traceability and compliance with the applicable directives and standards.
Up to 50% lighter than steel equivalents — reducing handling effort where steel meets every requirement except weight
Elongation above 12% before cracks — uniform material properties throughout the casting, with no weld seams to compromise them. Fatigue performance below endurance limit; mechanical properties retained up to 180°C.
Corrosion resistance proven across marine, petrochemical and outdoor environments — over decades of service
Custom alloy development for specialised industrial requirements — engineered when common aluminium alloys fall short
Available certifications and standards — others available on request, depending on application
From tanker terminals to theme parks
One metallurgical foundation, two industries — how EURAD’s cast aluminium expertise grew from pressure-containing spool pieces into the proprietary E39 wheel-core alloy.
Marine origin
EURAD’s cast aluminium expertise began with a problem the marine terminal industry had not been able to solve. Operators handling heavy steel reducers and adapters on tank terminals, marine loading arm jetties and tankers wanted a lighter alternative — but aluminium had been rejected for this pressure-containing, safety-critical service as insufficiently reliable. A dedicated metallurgical study changed that. Where most foundries default to AlSi compositions, EURAD established sand-cast AlMg: harder to cast, but inherently superior in elongation, fatigue resistance and corrosion performance — exactly what pressure-containing service in marine environments demands. The alloy is supplied per AD 2000-Regelwerk with a VdTÜV-approved framework, certified under PED 2014/68/EU.
Cross-industry application
The same metallurgical foundation found a second application after a theme park inspection group raised a safety question: rollercoaster wheel cores in service were exhibiting fragment failures under cyclic load. EURAD’s casting alloy met the threshold — elongation reliably above 12% before cracks and fatigue performance below the endurance limit (Wöhler-curve verified) — and was put to work in rollercoaster wheel cores.
Designated the proprietary E39 alloy for amusement-industry documentation, the material is referenced in attractions certified under EN 13814 (TÜV-certified), supported by EURAD’s certified mechanical-properties assurance under normal use and maintenance with heat exposure kept below 180°C.
Engineered cast aluminium products
Three engineered aluminium product groups for demanding industrial applications.
EURAD’s reducers and adapters — reducing and adapter spool pieces — are certified cast aluminium components for marine loading-arm operations. Up to 50% lighter than steel equivalents — reducing handling effort and operator strain at tank terminals, jetties and tankers. Cast as a single monolithic body, with no weld seams to fatigue under boat movement and loading-arm cyclic loads. Supplied with 3.1 material certification — aligned with TÜV application certification — for the alloy and PED 2014/68/EU Cat III Module H for pressure-containing applications, with corrosion resistance proven in marine environments.
Supplied as reducers (reducing spool pieces — e.g. 10″ ANSI 150# to DN200 DIN PN10 diameter transition) or adapters (adapter spool pieces — e.g. 8″ ANSI 150# to DN200 DIN PN10) with differing flange specifications at each end. Engineered for marine loading arm systems in accordance with EN 1474-1 / ISO 16904.
Aluminium gains strength at LNG cryogenic temperatures (−162°C) where steel becomes brittle — qualifying these cast spool pieces for cryogenic loading-arm service. Custom configuration adaptations can be engineered where standard designs require refinement. Company name and project markings can be cast directly into the body for permanent traceability — inherent to monolithic casting. Also referenced as aluminum reducers or aluminum spool pieces in US-specification installations.

Designed using EURAD’s proprietary E39 alloy, our wheel cores deliver durability and safety for rollercoasters in service with major theme park operators. The E39 alloy was developed to overcome the limitations of standard AlMg alloys as well as commonly used AlSi alloys — achieving elongation before cracks exceeding 12% (typically higher in production), fatigue performance below the endurance limit verified through Wöhler-curve analysis, and mechanical properties retained up to 180°C. This property retention covers both passenger-service operating conditions and the elevated curing temperatures of polyurethane re-treading, where conventional cast alloys risk over-aging and permanent loss of strength. EURAD provides certified mechanical-properties assurance on E39 in rollercoaster wheel core applications, conditional on normal use and maintenance with heat exposure kept below 180°C.
When standard aluminium alloys cannot meet your combined requirements, EURAD evaluates feasibility together with foundry engineering. Each case is considered on its own — mechanical, thermal and certification requirements, what is realistically achievable, and whether the development is worth pursuing. Each development path starts with technical feasibility assessment.

Marine loading arms & tank terminals
Marine loading arm jetties, tank terminals and tankers rely on EURAD’s lightweight cast aluminium reducers and adapters — reducing and adapter spool pieces for ship-to-shore loading-arm to tanker manifold connections, cast as monolithic bodies without weld seams for safer and more efficient handling operations.
Configure for your application →Rollercoasters in amusement parks
EURAD’s E39 alloy is used in rollercoaster wheel cores for predominantly TÜV-certified attractions where passenger safety and cyclic durability are critical. Elongation above 12% before cracks, fatigue performance below the endurance limit and retained mechanical properties up to 180°C qualify E39 for continuous cyclic service. E39 wheel cores have been in continuous service across multiple generations of rollercoasters in amusement parks since the early 2000s.
Specialised industrial applications
For specialised industrial applications where weight, strength, corrosion resistance and certification must coexist, EURAD evaluates each case individually. Each development trajectory begins with technical feasibility evaluation alongside foundry engineering.

Configure your cast aluminium reducers and adapters for marine loading arms (MLA) — the reducing and adapter spool pieces — with independent flange specifications per side, with DIN or ANSI flange drilling. The casting itself is produced in ANSI 150# and 300# classes; DIN and ANSI flange drillings can be combined independently to suit your application, with the design pressure for your configured spool piece determined by the lower pressure-class flange drilling.

Note: EURAD’s aluminium flange thicknesses deliberately deviate from steel ANSI/DIN specs — aluminium has a lower yield strength, so a thicker flange is required to achieve the same pressure rating. The drilling patterns do follow the standard.
