Physical properties: The properties that a material exhibits under the influence of light, gravity, temperature, electric fields, and magnetic fields are known as physical properties. These include the material’s electrical properties, magnetic properties, optical properties, density, and melting point. Mechanical properties: strength, plasticity, hardness, toughness, and fatigue resistance

The properties of metal materials can generally be divided into two categories: service properties and processing properties. Service performance refers to the properties that a material must possess under operating conditions, and it includes physical properties, chemical properties, and mechanical properties. Physical properties refer to the characteristics exhibited by metal materials under various physical conditions. These include: density, melting point, thermal conductivity, electrical conductivity, thermal expansion, and magnetism, etc. Chemical properties refer to a metal’s ability to resist chemical erosion by external agents at room temperature or at high temperatures. Including: corrosion resistance and oxidation resistance. Mechanical properties are the most important performance characteristics of metal materials. Metal mechanical properties refer to those characteristics related to elastic and inelastic responses under mechanical stress, or those involving the stress-strain relationship. It includes: strength, plasticity, hardness, toughness, and fatigue strength, etc. The processability of metal materials directly affects the quality of the parts after processing, and it is one of the factors that must be taken into consideration when selecting materials and determining the processing routes for parts. It includes casting properties, forming properties, welding properties, machining properties, and heat treatment properties, among others.
