The main density, melting point, thermal expansion, thermal conductivity, electrical conductivity and magnetic properties. Due to the different uses of machine parts, the requirements for their physical properties are also different. For example, aircraft parts are often made of low-density aluminum, magnesium and titanium alloys. Electrical conductivity of metal materials is often considered when designing motor and electrical parts.

Sometimes the physical properties of metal materials also have a certain effect on the machining process. For example, high speed steel thermal conductivity is poor, forging should be used at a low speed to heat up, otherwise easy to crack; The thermal conductivity of materials has a great influence on the temperature rise of cutting tools. For example, the melting points of tin-based bearing alloys, cast iron and cast steel are different, so the selected melting equipment, casting materials and so on are very different.
