Alloy 20 vs Copper Nickel and Titanium Fasteners
Alloy 20 is primarily selected for acidic and aggressive chemical processing, while material selection changes according to the operating environment and performance requirements.
For marine and seawater systems requiring strong saltwater corrosion resistance, Copper Nickel Fasteners can be considered. For lightweight, high-strength, and highly corrosion-resistant applications, Titanium Fasteners are another option.
| Material | Primary Strength | Typical Applications |
|---|---|---|
| Alloy 20 | Acid and chemical corrosion resistance | Chemical, pharmaceutical, fertilizer |
| Copper Nickel | Seawater and marine corrosion resistance | Marine, seawater, offshore |
| Titanium | High strength-to-weight ratio and corrosion resistance | Aerospace, chemical, medical |
