What Is the Strongest Type of Metal on Earth?
Searching for the toughest metal on the planet?
Tungsten is widely considered Earth’s strongest natural metal by tensile strength, though other alloys outperform it under certain conditions.
Let’s explore which metals truly dominate in strength, hardness, and industrial application.

What is Earth's strongest metal?
Not all “strong” metals behave the same under stress.
Tungsten is Earth's strongest pure metal in terms of tensile strength, resisting deformation even at extremely high temperatures.
Why Tungsten Leads the Pack
| Property | Value |
|---|---|
| Tensile Strength | ~1,510 MPa |
| Melting Point | 3,422°C (highest among metals) |
| Density | 19.25 g/cm³ |
| Common Use | Defense, aerospace, radiation shielding |
Despite its raw strength, tungsten is brittle and hard to machine. At Prime, we recommend tungsten only for static, high-heat or wear-resistant components, not for 精密CNC加工零件 requiring ductility or fine features.

What is the highest strength metal?
Looking beyond pure metals? Alloys often go further.
Maraging steel has the highest overall strength among metals when factoring in yield, tensile, and fatigue performance.
Top Strength Metals (By Application)
| Metal / Alloy | Max Tensile Strength (MPa) | Key Feature |
|---|---|---|
| Maraging Steel | ~2,000 | Strong and tough |
| Tungsten | ~1,510 | Best pure metal strength |
| Inconel | ~1,200 | High strength at high temps |
| Titanium (Grade 5) | ~1,100 | High strength-to-weight |
| Chromium | ~600 | Hard and corrosion-resistant |
At Prime, we use maraging steel in ISO认证铸造零件厂家 tooling and aerospace parts where extreme force and durability are key—especially when magnesium or aluminum alloys fall short.

What's harder than tungsten?
Strength isn’t always about tensile force—sometimes, it’s about hardness.
Diamond is harder than tungsten—but it’s a crystalline non-metal. Among metals, chromium and tungsten carbide are harder than pure tungsten.
Top Materials by Hardness
| Material | Mohs Hardness | Category |
|---|---|---|
| Diamond | 10 | Non-metal (carbon) |
| Tungsten Carbide | ~9 | Metal-ceramic |
| Chromium | 8.5 | Hardest pure metal |
| Tungsten | 7.5 | Extreme hardness + strength |
| Steel (Hardened) | ~7–8 | Heat-treated alloy |
At Prime, we offer 硬质合金零件加工 for clients who need both hardness and wear resistance—especially for custom tools, dies, and heavy-duty industrial fasteners.

What's stronger, iron or titanium?
Iron is everywhere—but does it outperform titanium?
Titanium is significantly stronger than pure iron, offering better tensile strength, fatigue resistance, and corrosion protection—at a fraction of the weight.
Titanium vs. Iron
| Property | Iron | Titanium |
|---|---|---|
| Tensile Strength | ~370 MPa | ~1,100 MPa |
| Density | 7.87 g/cm³ | 4.51 g/cm³ |
| Corrosion Resistance | Low | Excellent |
| Strength-to-Weight Ratio | Low | Very High |
That’s why titanium is widely used in aircraft frames, implants, and 精密CNC加工零件, while iron is used more in structural beams, castings, or budget-heavy parts.
At Prime, we help customers upgrade from heavy iron parts to lightweight, high-strength titanium for better performance and efficiency.
