In the metal fabrication world, you will hear the words “tensile strength” get thrown around. Many times, customers of ours and those just learning about metal fabrication will always ask about it and how it is pertinent to manufacturing. So this blog post will be intended to close this gap.
First off, the word “tensile” means stretch or flex. Many different types of metal have some elasticity. So stretch strength or flex strength gives you a better idea of what it means. Simply put, tensile strength is the the amount of stretching that can be done to metal before it breaks. When manufacturing with various types of metals, it is important to be aware of a metal’s tensile strength since it is a measurement of how the metal will perform a certain application.
How is tensile strength determined?
According to Steel Forge, metals’ tensile strength is “calculated by dividing the area of the material tested (the cross section) by the stress placed on the material, generally expressed in terms of pounds or tons per square inch of material.” In order to measure a metal’s tensile strength, a test piece of metal is put under a stress test where the metal is stretched with gradual increased force until the metal breaks. The amount of forced used to break the metal determines the metal’s tensile strength in psi (pounds per square inch).
What are the tensile strengths of common metals?
Here is a list of common metals and their tensile strengths according to Material Property Data:
Tensile Strength (psi)
|Aluminum Alloy 5052-H32||33068|
|Aluminum alloy 6063-T6||35969|
|Mild steel 1090||121976|
|Stainless steel AISI 302 – Cold Rolled||124732|
|Steel AISI 4130||160991|
|Structural steel ASTM A36 steel||58015|
