sintered metals is a process in which metal powder is placed in a mold and metallurgically bonded under high temperature and high pressure to form a blank.
During the sintering process, the overall organizational structure of the metal powder and the contact surface area between the particles are improved, so that the metal material has better mechanical strength and plasticity, which can be used to manufacture parts with high strength requirements and complex shapes.
Metal melting is the process of heating the metal above the melting point to convert it into a liquid state, and then cooling and solidifying it to form metal blanks of different shapes. Various complex parts and devices can be processed from the melted metal material, such as engine cylinders, aircraft engine blades, ship steering wheels and more.
Differences between metal sintering and melting
1. Different processing methods
Metal sintering and melting have different processing methods. Metal sintering is to press metal powder in a mold, without heating the metal to a molten state; while metal melting requires heating the metal above the melting point to make it liquid.
2. Different metal states
The blanks obtained by metal sintering are directly metallurgically bonded by metal powders, and the joints between the metals are solid; while the metal blanks obtained after metal melting are formed by cooling and solidifying liquid metal into solid. Therefore, the blanks processed by metal sintering are relatively uniform in material and easy to process and shape; while the metal materials obtained by metal melting have certain differences in organizational structure and performance.
3. Different application areas
The application of metal sintering is mainly concentrated in the manufacture of high-strength, high-precision, and complex-shaped parts and devices, such as vehicle engine cylinders, gas turbine guide vanes, ship brakes, etc.; while metal melting is widely used, which can be used to manufacture large parts, such as steel bridges and steel buildings, and can also manufacture basic parts with complex structures and sizes, such as aircraft engines.
Of course, through the above analysis of the concepts and principles of metal sintering and melting, it can be seen that there are great differences between metal sintering and melting in terms of processing methods, metal states, and application areas.
