Metal Strength Chart – Mechanical Properties Chart of Different Metal Grades and Alloys | CNCLATHING


Strength is a critical factor in metal uses, for example, some applications require stronger aluminum parts, while some products need high steel hardness or yield strength of steel, this may determine the selection of CNC machining material or product design. Here we collect the metal strength chart (tensile, yield strength, hardness, and density included) and mechanical properties chart of common metals of different grades for your reference.

Introduction to Different Types of Metal Strength

Strength refers to the ability of materials to resist deformation and failure under the action of external forces. The main indexes can be divided into tensile strength (the most basic strength index), compressive strength (caused by squashing), yield strength, shear strength and more. How to define different types of metal strength and what are they used for?

1) Yield strength: the stress a machined component or material can withstand without permanent deformation or the stress of the yield point at which the part starts plastic deformation. It is used to determine the maximum allowable load in the object.

2) Tensile strength: the minimum force required to pull the material to break or the maximum load that a part can support without fracture when being stretched, divided by the original cross-sectional area of the material, commonly expressed in units of pounds per square inch or psi.

3) Ultimate strength: the utmost tensile, compressive, or shearing stress that a given unit area of a specific material can bear without breakage or deformation.

4) Compressive strength: opposed to tensile strength, the maximum compressive stress a solid material can sustain without fracture under gradually applied load. It can be used to measure the capacity of the material to withstand loads tending to reduce the size. 

5) Impact strength: the maximum impact or suddenly applied force a part can take before its failure. It’s actually used to measure the amount of energy the material can absorb at the limited state.

6) Shear strength: the maximum shear load a material can withstand before failing divided by its cross-sectional area.


Generally, Steel, Titanium, Tungsten and Inconel are considered the strongest four metals.
