There are certain metals found throughout the world that display superior characteristics to standard alloy metals. These strong metals are often used for industrial applications that require the beneficial features only found in high-strength metals. This article will explore the types of high-strength metals and the fundamental differences that separate them.
A metal’s strength can be categorized into several categories, including hardness, yield strength, and compressive strength. These metal strength measurement standards accurately gauge the overall strength of a metal. Metals commonly found in nature, such as chromium, tungsten, and titanium, display excellent strength characteristics; however, they cannot match the intensity of manufactured metals such as steel and Inconel alloys.
Several factors affect the strength value of a metal. Characteristics such as tensile, yield, compressive, and impact strength comprise the total strength rate. These strength values provide important information regarding the overall intensity of the metal.
Yield strength refers to a metal’s ability to resist perpetual deformation or bending. Yield strength ultimately tests a material’s elastic limitations. The intent is to discover how much stress it requires to exceed the material’s yield point or when the material will not return to its original shape upon removal of the stress.
A widely accepted test for compressive strength is Mohs Hardness Test. The test relies on a scale that rates minerals from 1-10, or softest-hardest. To test a metal’s compressive strength, an external force places pressure upon the metal and then tracks to what degree the material can resist size reduction. Compressive strength tests measure a metal’s ability to withstand compression.
As the title of the strength test indicates, impact strength is a measure of the amount of force a metal can withstand without shattering or fracturing. Impact strength measures how much forceful energy a metal can absorb before it fails.
Tensile strength is a direct measure of the force required to stretch or pull something apart. Tensile strength directly measures a material’s ability to resist tension. A material with low tensile strength would pull apart more quickly than a material with high tensile strength.
High-strength metals are incredibly reliable for many applications, whether they are found exclusively in nature or manufactured via laboratory design and manmade alloying processes. The following list of metals provides superior strength characteristics.
Chromium is a hard metal known for its silver, shiny, “polished”
appearance. It has a high melting point and a stable crystalline
structure. Both 304 and 316 grade stainless steels contain a minimum
of 10% chromium by weight.
Chromium metal rates highest on the
Mohs hardness scale, but it is brittle and must be mixed with other
metals for greater tensile strength. The best example of a metal alloy
that utilizes chromium for increased strength characteristics
is stainless steel. Chromium is also used regularly in chrome
plating.
Chromium Applications
Tungsten has the highest tensile strength of any pure metal – up
to 500,000 psi at room temperature. It has the highest tensile
strength even at temperatures over 1,500°C. Tungsten is so dense
that it resists melting, even under extremely high heat. However,
tungsten metal is brittle, making it less useable in its pure
state.
Tungsten Applications
Pure titanium has a higher tensile strength than standard steel
but is less dense, giving it a very high strength-to-weight ratio.
However, steel alloys are more robust than pure titanium. Titanium
also enhances corrosion resistance and is resistant to corrosion,
rust, chemicals, and acids.
Titanium is extremely strong. It
possesses an atomic number of 22, an atomic weight of 47.90, and a
density between aluminum and stainless steel. It can alloy nearly
every element except copper and aluminum, and it is most often used as
an alloy in iron. It has a melting point of 3074 degrees Fahrenheit
and a boiling point of 6395 degrees F.
Inconel is an alloy of nickel and chromium, with several other
elements, such as molybdenum. Inconel comes in several different
grades and is known for its high strength at high temperatures and
corrosion resistance.
Inconel alloys include 600, 601, 625, 690,
718, 751, 903, and 939. These alloys contain varying amounts of nickel
and chromium, resulting in metal alloys commonly used for high-profile
applications, including aerospace, nuclear, and other high-temperature
applications.
Inconel Applications
Steel itself is an alloy of carbon and iron. Alloys of steel with
additional elements added, such as carbon (tool) steel and stainless
steel, can be crafted much more potent than standard steel. Each alloy
is specifically designed to optimize different properties for
different applications.
Tensile strength, corrosion resistance,
hardness, impact resistance, yield strength, and other properties
depend on the alloying elements chosen and the processes used.
Steel Alloy Applications
Scientists continue to develop and test new alloys with even more
excellent properties. In recent years, several university research
groups have announced new types of magnesium alloys that exhibit
exceptional strength, lighter weight, and high corrosion resistance.
These new materials are already being used in smartphone and laptop
cases, electric batteries, and medical implants.
