DOMADIA™ Silverin 500 – The Nickel Copper Alloy That Redefines Durability
🌊Real Story: Offshore Failure Turned Success
The Problem That Kept Coming Back
An offshore rig operator was facing repeated equipment failures.
Corroded shafts, worn-out valves, and emergency shutdowns were a constant headache.
Each repair led to more downtime, costing time and money.
The culprit? Conventional copper nickel materials that couldn’t handle seawater or high stress.
A Game-Changing Decision
Rather than repeating the cycle of replacement, the team made a smarter move.
They switched to DOMADIA™ Silverin 500—a nickel copper aluminum alloy engineered for extreme conditions.
Fast forward two years:
✔️ No corrosion
✔️ No breakdowns
✔️ No interruptions
The outcome wasn’t luck.
It was the result of using the right material from the start.
Why Replacing Isn’t Always the Right Fix
Too often, engineers rely on standard materials like copper nickel, assuming they’ll be “good enough.”
In practice, these alloys fall short—especially in harsh environments like offshore rigs or chemical plants.
That’s where Silverin 500 shines.
It’s built with strength, longevity, and corrosion resistance in mind.
Built-In Protection That Lasts
So, does nickel copper rust? Under pressure, it can.
But DOMADIA™ Silverin 500 takes protection further.
Thanks to added aluminum and titanium, it offers:
- Stronger resistance to saltwater and acid
- Higher durability under stress
- Long-term savings on maintenance
In short, it’s not just a fix—it’s a future-proof solution.
🔍 What Is Silverin 500?
DOMADIA™ Silverin 500 is a nickel copper aluminum alloy (NiCu30Al) developed to outperform traditional copper nickel materials. It’s age-hardenable, non-magnetic, and engineered for exceptional corrosion resistance.
