The different types of metal strength.
Metal strength can be measured and evaluated in various ways, depending on the type of force or load applied to the metal. The three main types of metal strength are:
- Tensile strength: This type of strength refers to the maximum amount of tensile force or stress a metal can withstand before breaking or deforming. Tensile strength is commonly measured in pounds per square inch (psi) or megapascals (MPa).
- Yield strength: This type of strength refers to the amount of stress a metal can withstand without permanently deforming. Yield strength is commonly measured in psi or MPa.
- Hardness strength: This type of strength refers to the resistance of a metal to indentation or scratching. Hardness strength is commonly measured using a hardness tester, such as the Rockwell or Brinell hardness test.
Understanding the different types of metal strength is essential for choosing the right metal for a specific application and ensuring its performance and durability.
The different terms used in the metal strength
- Tensile strength – the maximum stress that a metal can withstand while being pulled or stretched before breaking.
- Yield strength – the point at which a metal begins to permanently deform under stress.
- Compressive strength – the maximum stress that a metal can withstand while being squeezed or compressed.
- Shear strength – the maximum stress that a metal can withstand while being cut or sheared.
- Hardness – the measure of a metal’s resistance to deformation and indentation.
- Toughness – the ability of a metal to absorb energy and deform without breaking.
- Elasticity – the ability of a metal to return to its original shape after being deformed.
- Fatigue strength – the ability of a metal to withstand repeated cycles of stress without failing.
- Ductility – the ability of a metal to be easily formed or drawn into wire without breaking.
- Malleability – the ability of a metal to be easily molded or hammered into different shapes without breaking.

The factors that affect metal strength.
How metal strength can be affected by environmental factors, such as corrosion and wear
- Corrosion: Corrosion is the gradual degradation of a metal due to chemical reactions with its environment. Corrosion can reduce the strength and durability of a metal, especially in high-stress applications.
- Wear: Wear is the gradual loss of material due to friction, abrasion, or erosion. Wear can reduce the strength and performance of a metal, especially in high-stress applications.
- Temperature: Temperature can affect the strength of a metal by changing its microstructure and mechanical properties. High temperatures can reduce the strength of some metals, while low temperatures can increase the strength of others.
- Composition: The chemical composition of a metal can affect its strength, ductility, and hardness. Different alloys and materials can have different strength characteristics, depending on their composition and manufacturing process.
- Fatigue: Fatigue is the process of gradual weakening of metals due to repeated loads or stresses. Fatigue can occur in various applications, such as aircraft, bridges, and pipelines. Over time, fatigue can reduce the strength and reliability of metals, leading to failure or deformation.
- Heat treatment: The strength of a metal can be affected by heat treatment processes, such as annealing, quenching, and tempering. These processes can change the microstructure of a metal and improve its strength, ductility, and hardness.
To ensure the performance and durability of a metal in a specific application, it is important to consider its susceptibility to corrosion, wear, and temperature changes, as well as it’s chemical composition and manufacturing process.
How to choose metal strength for a specific application?
