The exercise of grouping metals from the strongest to the weakest happens to be a difficult task. The main obstacle lies in defining what strength means. You can determine strength by several properties.
In that regard, you can only define the metal by a particular strength. Strength occurs in four ways, which you can use to evaluate one specific metal. We will be highlighting different metals with their specific strength for one to understand the difference.
- 1 Types of Strengths
- 2 The Strongest Metals in the World
- 3 Final Thoughts
Types of Strengths
There are four types of strengths are listed below:
1. Tensile Strength
By talking about tensile strength, we exactly refer to the ability of a particular metal to resists tension. Or even better, the amount of the required strength to pull apart or to stretch. If the material has high tensile strength, it will not stretch easily and vice versa.
2. Compressive Strength
The compressive strength is that particular ability to tolerate squeeze. It is the ability to withstand being compressed together. For one to check the compressive strength of a specific metal, you can use external forces to press the metal. You should track the level at which the material will resist reduction.
One of the most commonly used methods to test compressive strength is the Mohs Hardness Test. The test will rate the softest to the hardest metal to a scale of 1-10.
3. Yield Strength
A particular metal can withstand bending or permanent deformation. In other words, you will be testing the elastic limit of the material. You can determine it by performing a bend test.
As you do the bend test, you will determine the amount of stress that you will require to exceed the yield point. The yield point talks about that particular point whereby the material will not return to its original shape as you remove stress.
4. Impact Stress
Impact stress of a metal is the ability of the metal to tolerate a blow without shattering or fracturing. You will determine the limit of that material to the amount of energy it can absorb when it encounters impact.
The Strongest Metals in the World
The most robust metal will come in the form of an alloy. Specifically, an alloy is a combination of two or more metals to improve the properties of the final product. Of all the metals, steel happens to be among the strongest metal alloys in the word.
Carbon steel has a carbon content of 2.1 %. Moreover, the alloy has 290 megapascals (MPa) of yield strength. On the other hand, it features 580 MPa of tensile strength. This alloy is extremely-impact resistant. It will score six on the Mohs scale.
This alloy has a yield strength of 1560 MPa. Its composition features 11 % chromium. It also has a nickel combination to increase its corrosion resistance. The cool thing is that it also has 1600 MPa of tensile strength.
The alloy has a composition of 15-25% of nickel together with other elements. They are Titanium, cobalt, aluminum, and molybdenum. It features a low carbon content. It has a remarkable yield strength that ranges from 1400-2400 MPa.
People use this alloy to make various tools. It is an alloy of two metals being Tungsten and cobalt.
This ally is superior to severe conditions. It can comfortably withstand high temperatures. The alloy is a combination of chromium, nickel, and austenite.
The metal has high tensile strength as compared to ordinary metals. Typically, Tungsten is brittle and can shatter under the impact. You can combine Tungsten with steel and other metals to produce a strong alloy.
Chromium is a metal that scores high on the Mohs scale. Precisely, it will score 9 out of ten. Unfortunately, it will score poorly in terms of tensile and yield strengths. You can make it hard by adding other alloys.
One can define Titanium as a highly tensile metal, and it can be stronger than Tungsten. It will score poorly on hardness. Most of its alloys are lightweight and strong. Furthermore, most of its application are majorly in aerospace.
This alloy comes by combining two metals, Tungsten, and carbide. You can use it to construct knives, drill bits, circular saw blades, among others. The alloy has tensile strengths that range from 500 to 1050 MPa. Still, its yielding strength ranges from 300 to 1000 MPa.
It is a component of steel. Many use this metal to manufacture weapons and other useful tools. The cast iron will averagely measure on the Mohs scale with a score of 5. The yield strength will measure 246 MPa, and tensile strength is about 414 MPa.
From the above discussion, the strongest metal on the earth will be steel. On the face of it, the steel alloy is usually versatile. Manufacturers craft it to meet any requirement. Also, one can craft it with other alloys to make the strongest metal in the universe.
When it comes to the hardness aspect, chromium takes the lead. It is true to say that diamond is the hardest known mineral. It will be clear to differentiate those two. Chromium is the hardest metal and not the hardest mineral.
You can combine chromium with steel to make the hardest alloy ever.
Metals play a critical role in improving the lifestyle of a human being. These metals are useful when manufacturing specific items that enhance the life of the users. It would help if you understood their properties.
Steel is the strongest metal on earth due to its outstanding properties. You can manipulate it to make various durable items. The alloys that come with it are usually strong and hard. Nonetheless, most of the steel-made things will last for a longer duration.
Do you desire to have a metal item that comes from the strongest metals on earth? It could be helpful if you deliberately understood the properties of the said metals. The alloys have excellent features that can be useful for your assignments.
