Titanium Tube Price vs Copper
May 22, 2026
| Material | Upfront Cost | Service Life | Long Term Cost |
|---|---|---|---|
| Copper tube | Low | 5-10 years (in seawater) | High – needs replacement |
| Titanium tube | 2-3x higher | 20-30+ years (in seawater) | Lower – no replacement |
If your application involves seawater, brackish water, or chlorides, titanium tube is more cost effective long term – even though it costs more upfront.
Current market prices (May 2026)
ASTM B338 Gr.1 titanium tube vs ASTM B111 C12200 copper tube. Same size: 25.4mm OD x 1.24mm wall. FOB China port.
| Comparison | Gr.1 Titanium Tube (ASTM B338) | Copper Tube (C12200) |
|---|---|---|
| Market price (USD/kg) | $28 – 38 | $9 – 14 |
| Density (g/cm³) | 4.51 | 8.94 |
| Weight per meter (kg/m) | 0.42 | 0.83 |
| Price per meter (USD/m) | $11.8 – 16.0 | $7.5 – 11.6 |
| Price ratio | 40-80% more per meter | Baseline |
Titanium costs 2-3x more per kg, but because its density is half that of copper, the price per meter is only 40-80% higher – not as big a gap as most buyers expect.
Why titanium tube is cheaper long term
titanium does not corrode in seawater. Copper does.
Copper tube in seawater – the reality
| Problem | What happens |
|---|---|
| Erosion-corrosion | High water velocity erodes the protective film |
| Pitting | Localized attack creates holes |
| Sulfide attack | Polluted seawater accelerates corrosion |
| Galvanic corrosion | Copper reacts with other metals |
Typical copper tube service life in seawater: 5-10 years. Then you replace it. Labor + downtime + new material.
Titanium tube in seawater – the reality
| Advantage | What happens |
|---|---|
| Self-repairing oxide film | Immediate re-forms if damaged |
| No velocity limit | Can handle high flow without erosion |
| No pitting | Uniform corrosion is negligible |
| No galvanic issues | Compatible with most metals |
Typical titanium tube service life in seawater: 20-30+ years. You install it once. Then you forget it.

| Cost Item | Copper Tube | Gr.1 Titanium Tube |
|---|---|---|
| Initial material cost | $900 – 1,200 | $1,200 – 1,600 |
| Initial installation labor | $400 | $400 |
| First replacement (year 8) | $1,300 – 1,600 | $0 |
| Second replacement (year 16) | $1,300 – 1,600 | $0 |
| Downtime cost (2 x $2,000) | $4,000 | $0 |
| 20-year total cost | $7,900 – 8,800 | $1,600 – 2,000 |
| 20-year savings | - | Save $6,000 – 6,800 |
Cost comparison by service life
| Service Life | Copper Cumulative Cost | Titanium Cumulative Cost | Savings with Titanium |
|---|---|---|---|
| 5 years | $1,300 – 1,600 | $1,600 – 2,000 | Titanium costs $300-400 more |
| 8 years | $2,600 – 3,200 (after first replacement) | $1,600 – 2,000 | Titanium starts saving |
| 10 years | $2,600 – 3,200 | $1,600 – 2,000 | Save $600-1,600 |
| 15 years | $3,900 – 4,800 | $1,600 – 2,000 | Save $1,900-3,200 |
| 20 years | $5,200 – 6,400 (after second replacement) | $1,600 – 2,000 | Save $3,200-4,800 |
Break-even point: Approximately 7-9 years. After that, titanium is pure savings.
When is copper tube still a good choice?
Copper tube is fine for:
Clean fresh water (no chlorides)
Low velocity (< 1.5 m/s)
Short term projects (< 5 years)
| Application | Recommended Grade | Key Property |
|---|---|---|
| Fresh water cooling | C12200 (DHP Copper) | General purpose, good thermal conductivity |
| Seawater – low velocity (<1.5 m/s) | C70600 (Cu-Ni 90/10) | Good resistance to seawater corrosion |
| Marine / shipboard cooling | C71500 (Cu-Ni 70/30) | Higher strength, better erosion resistance |
| Condensers (fresh water) | C12200 | Cost effective for clean water |
| Heat exchangers (fresh water) | C12200 or C70600 | Depends on water chemistry |
| High temperature fresh water | C12200 | Good thermal stability |
We also supply copper tube (C12200, C70600, C71500). If you need copper tube, please email us with your size and quantity requirements.
When is titanium tube worth the investment?
| Application | Why titanium is worth it |
|---|---|
| Seawater heat exchangers | No corrosion, no replacement |
| Power plant condensers | 30+ year life, minimal downtime |
| Desalination plants | Resists brine and high temperatures |
| Offshore platforms | Harsh environment, difficult to replace |
| Shipboard cooling | Saltwater exposure 24/7 |
| Chemical plants with chlorides | Resists pitting and SCC |
| Application | Recommended Grade | Key Property |
|---|---|---|
| Seawater – any velocity | Gr.1 | No velocity limit, best formability |
| Seawater – U-bent heat exchanger | Gr.1 | 24% elongation for bending |
| Seawater – high pressure | Gr.2 | Higher strength (275 MPa yield) |
| Seawater – stagnant / crevice conditions | Gr.7 (Ti-Pd) | Superior crevice corrosion resistance |
| Fresh water cooling | Gr.1 or Gr.2 | Both work, overkill but long life |
| Chemical / chloride environments | Gr.1, Gr.2, or Gr.7 | Excellent corrosion resistance |
