Which Is Stronger: Magnesium or Titanium?
Trying to decide between magnesium and titanium for strength-critical parts?
Titanium is significantly stronger than magnesium in terms of tensile strength, fatigue resistance, and corrosion durability.
Let’s compare them side by side to help you choose the right material.

Is magnesium stronger than titanium?
Many confuse lightness with strength when choosing metals.
No—magnesium is much lighter but not stronger than titanium. Titanium offers more than double the tensile strength and superior durability.
Magnesium vs. Titanium: Key Comparison
| Property | Magnesium | Titanium |
|---|---|---|
| Density (g/cm³) | 1.74 | 4.51 |
| Tensile Strength (MPa) | ~200–330 | ~900–1,200 |
| Corrosion Resistance | Low | Very High |
| Machinability | Excellent | Moderate |
| Cost | Low | High |
Magnesium shines in applications where weight savings matter more than brute strength—like drones or casings. Titanium is used where failure is not an option—like aerospace fasteners and high-performance 精密CNC加工零件.
At Prime, we help clients balance both depending on project needs.

What metal is stronger than magnesium?
If magnesium isn’t the strongest, what beats it?
Several metals are stronger than magnesium—including titanium, steel, aluminum alloys (7000 series), and Inconel.
Relative Strength of Common Metals
| Metal | Approx. Tensile Strength (MPa) | Notes |
|---|---|---|
| Magnesium Alloy | 200–330 | Light, weak |
| Aluminum 7075 | 570–700 | Aircraft-grade, affordable |
| Titanium Grade 5 | 900–1,200 | Excellent strength-to-weight |
| Stainless Steel | 500–800 | Durable, corrosion-resistant |
| Inconel | 1,200+ | Extreme heat and fatigue resistance |
When designing structural 定制冲压件 or stress-critical fasteners, Prime recommends magnesium only for lightweight frames, not high-load components. Titanium or high-strength aluminum is more appropriate when durability is key.

What material is stronger than titanium?
Titanium is tough—but is it the toughest?
Yes, titanium is extremely strong, but it’s not the strongest. Materials like tungsten, Inconel, carbon fiber composites, and certain ceramics exceed titanium in specific metrics.
Top Materials Stronger Than Titanium (in Some Aspects)
| Material | Strength Type | Tensile Strength (MPa) |
|---|---|---|
| Tungsten | Compression | ~1,500 |
| Inconel | Heat + fatigue | ~1,200+ |
| Carbon Fiber | Tensile per weight | ~3,500 |
| Boron Carbide | Hardness | 30 GPa (Vickers) |
| Steel (Maraging) | All-around | ~2,000 |
But these materials also come with tradeoffs—cost, machinability, or brittleness. That’s why Prime matches materials to use-case, helping buyers get performance without overpaying for properties they don’t need.

Which is more reactive, titanium or magnesium?
Not all strength is physical—some metals also differ chemically.
Magnesium is significantly more reactive than titanium, especially in moist or salty environments where it corrodes quickly.
Reactivity Chart
| Metal | Reactivity Level | Behavior |
|---|---|---|
| Magnesium | Very High | Reacts with water, oxygen easily |
| Titanium | Low | Forms passive oxide layer |
| Aluminum | Medium | Corrosion-resistant when anodized |
| Steel | Medium–High | Rusts unless treated |
This makes titanium ideal for long-term ISO认证铸造零件厂家 applications where exposure to the elements is constant. At Prime, we machine both materials—magnesium for cost-effective weight reduction, and titanium for ultra-reliable performance.

结论
Titanium is far stronger and more corrosion-resistant than magnesium, though magnesium wins on weight and machinability.
