Understand the characteristics of materials together

Mechanical performance
Mechanical properties refer to the properties exhibited by metal materials under stress, mainly including:

Strength: The ability of a material to resist damage (excessive plastic deformation or fracture).
Plasticity: The ability of a material to undergo permanent deformation under load without failure.
Hardness: The ability of a material to resist being pressed into its surface by hard objects.
Resilience: The ability of a material to absorb energy and resist fracture when subjected to impact or rapid loading.
Fatigue: The phenomenon of material fracture under repeated or alternating stress.

Physical performance
The physical properties involve the physical and chemical responses of metal materials, including:

Density: The mass per unit volume that affects the weight and specific strength of a material.
Melting point: The temperature at which a material transitions from a solid state to a liquid state.
Thermal expansion: The change in material volume with temperature fluctuations.
Magnetic properties: The ability of a material to attract ferromagnetic objects.
Electrical performance: mainly considering the electrical conductivity of the material.

Chemical properties
Chemical properties describe the characteristics of metal materials undergoing chemical reactions with the environment, mainly including:

Corrosion resistance: The ability of a material to resist chemical corrosion.
Oxidation resistance: The ability of a material to resist oxidation at high temperatures.

Process performance
The process performance reflects the characteristics of metal materials during the processing, including:

Cutting performance: The degree of difficulty in which a material is processed by a cutting tool.
Malleability: The ease of forming a material during pressure processing.
Castability: The difficulty of melting and casting materials into castings.
Weldability: The ease with which materials can be bonded together after rapid local heating.

Thermal conductivity and electrical conductivity
Many metal materials, especially copper and aluminum, have excellent conductivity and thermal conductivity, making them ideal choices for manufacturing cables and heat sinks.
High and low temperature resistance performance
Metal materials can maintain their properties under extreme temperature conditions, making them suitable for high-temperature furnaces and low-temperature environments.

Conclusion
These characteristics of metallic materials make them indispensable materials in modern industry and technology. With the development of technology, the demand for high-performance metal materials continues to grow, driving the advancement of new material research and processing technology. The rational selection and application of metal materials are of great significance for improving product performance, reducing costs, and achieving sustainable development.
