Still not sure? Keep reading for the deep dive into material science, real-world performance, and professional recommendations.
Understanding the Materials: Chemistry Matters
What Is Brass? (The Popular Choice)
Brass = Copper (60-70%) + Zinc (30-40%)
Properties:
- Warm golden color that darkens with age
- Excellent corrosion resistance in most environments
- Easier to machine and manufacture (lower cost)
- Develops protective brown/green patina
- Good strength and durability
Marine-grade brass (like naval brass) includes small amounts of tin to enhance saltwater resistance.
What Is Bronze? (The Heavy-Duty Champion)
Bronze = Copper (88-95%) + Tin (5-12%)
Properties:
- Darker golden-brown to brown-red color
- Superior corrosion resistance to brass
- Harder and stronger than brass
- More expensive to manufacture
- Develops rich brown patina
- Preferred for severe marine environments
Why bronze costs more: Tin is more expensive than zinc, and bronze is harder to machine and cast.
What About Copper? (The Artistic Option)
Copper = 99.9% Pure Copper
Properties:
- Brilliant orange-gold when new
- Develops stunning blue-green verdigris patina
- Excellent corrosion resistance
- Softer than brass or bronze (more prone to dents)
- Most expensive option
- Highly prized for aesthetic appeal
Copper's magic: The verdigris patina is actually copper carbonate—a protective layer that prevents further corrosion. That's why copper roofs last 200+ years.
The Science of Corrosion Resistance
How Saltwater Attacks Metal
Saltwater contains dissolved sodium chloride (salt) that acts as an electrolyte, accelerating electrochemical corrosion:
Steel in saltwater: Rapid oxidation (rust), complete failure in months
Aluminum in saltwater: Slower corrosion, eventual failure
Brass in saltwater: Dezincification (zinc leaches out), eventual weakening
Bronze in saltwater: Minimal corrosion, can last centuries
Copper in saltwater: Develops protective patina, exceptional longevity
Dezincification: Brass's Achilles Heel
In severe saltwater environments, zinc can leach out of brass, leaving porous copper behind. This "dezincification" weakens the fixture over time.
How to prevent dezincification:
- Use naval brass (includes tin inhibitor)
- Apply protective finish or let patina develop
- Or simply choose bronze for harsh saltwater
Naval brass (what DockLights.com uses) is specifically formulated to resist dezincification with tin additives.
Bronze's Superior Performance
Bronze doesn't contain zinc, so dezincification cannot occur. The copper-tin alloy forms a stable, protective patina that actually improves corrosion resistance over time.
Result: Bronze fixtures installed in 1800s are still functional today. That's 200+ years of perfect performance.
Real-World Performance Comparison
Freshwater Docks (Lakes, Rivers, Non-Tidal)
Brass: Excellent performance, 50+ year lifespan expected
Bronze: Excellent performance, 100+ year lifespan expected
Verdict: Both work perfectly. Choose brass to save money.
Best choice: Brass nautical lights from DockLights.com
Mild Saltwater (Protected Bays, Low Salinity)
Brass: Very good performance, 30-50 year lifespan expected
Bronze: Excellent performance, 80-100+ year lifespan expected
Verdict: Brass works well. Bronze offers extra longevity.
Best choice: Either option works. Budget typically decides.
Harsh Saltwater (Open Ocean, High Salinity)
Brass: Good performance with naval brass formulation, 20-40 years
Bronze: Excellent performance, 50-100+ year lifespan expected
Verdict: Bronze strongly recommended for this environment.
Best choice: Bronze dock lights from DockLights.com
Hurricane & Storm-Prone Areas
Brass: Works if naval brass formulation, 20-40 years
Bronze: Superior due to greater strength, 50-100+ years
Verdict: Bronze's hardness resists impact damage better.
Best choice: Heavy-duty bronze piling lights that can survive hurricane-force winds
Commercial & High-Traffic Applications
Brass: Good for moderate use, may show wear over decades
Bronze: Excellent for heavy use, superior scratch/dent resistance
Verdict: Bronze's hardness makes it ideal for commercial settings.
Best choice: Bronze for marinas and restaurants, brass for yacht clubs and private docks

- Requires ongoing maintenance effort
- Not recommended for marine environments
For natural patina (recommended):
- Allow natural aging process
- Rinse occasionally with fresh water
- Zero maintenance required
- Patina actually protects the metal
Most waterfront property owners prefer the natural patina because:
1. Looks authentic and distinguished
2. Protects the metal from corrosion
3. Requires zero maintenance
4. Gets better looking over time

Common Myths Debunked
Myth #1: "Brass turns green and looks ugly"
Truth: Brass develops brown patina with subtle green accents. It looks distinguished and antique, not "ugly." The full blue-green patina is actually copper/bronze, not brass.
Myth #2: "Bronze is just more expensive brass"
Truth: Bronze is a completely different alloy with superior properties. It's more expensive because it performs better, not as a marketing gimmick.
Myth #3: "You need to polish brass/bronze to prevent corrosion"
Truth: The patina is the corrosion protection. Polishing removes this protective layer and accelerates deterioration.
Myth #4: "Chrome or stainless looks better and lasts longer"
Truth: Chrome is plating that will eventually fail. Stainless can corrode in saltwater. Solid brass/bronze outlasts both.
Myth #5: "All brass is the same"
Truth: Marine-grade brass from DockLights.com uses naval brass formulations with tin additives that resist dezincification. Hardware store brass will fail quickly in saltwater.
