Metal properties
Material properties describe how a substance behaves under different conditions, including its mechanical strength, thermal stability, electrical conductivity, and chemical resistance. These properties determine how materials are selected and used in engineering, construction, electronics, and everyday products.
Categories of Material Properties
Mechanical properties
Tensile strength, hardness, toughness, elasticity, ductility, fatigue resistance.
Example: Steel has high tensile strength, while rubber is highly elastic.
Thermal properties
Heat capacity, thermal conductivity, expansion coefficient, melting point.
Example: Copper conducts heat well, while ceramics resist high temperatures.
Electrical properties
Conductivity, resistivity, dielectric constant, piezoelectricity.
Example: Silicon is a semiconductor, while silver is an excellent conductor.
Magnetic properties
Permeability, coercivity, remanence.
Example: Iron is ferromagnetic, while aluminum is non-magnetic.
Chemical properties
Corrosion resistance, oxidation, reactivity, solubility.
Example: Stainless steel resists corrosion, while sodium reacts strongly with water.
Optical properties
Transparency, refractive index, absorption, reflectivity.
Example: Glass is transparent, while metals are reflective.
