Metal forgings are the key parts widely used in the industrial field, and their performance and quality have an important impact on the safety, stability and life of the entire mechanical equipment. Material selection is an important link in the design and manufacture of metal forgings. This paper will deeply discuss the selection of different materials and their performance characteristics to provide reference for the design and manufacture of metal forgings.
Carbon steel
Carbon steel is one of the most commonly used materials in the manufacturing of metal forgings, its advantages are high strength, good plasticity, and relatively low price. However, carbon steel has poor corrosion resistance and needs to be treated with corrosion protection during processing and use.
Stainless steel
Stainless steel has excellent corrosion resistance and high temperature resistance and is often used to manufacture metal forgings that work in corrosive environments and high temperatures. However, its price is high, and its plasticity and toughness are relatively poor.
Aluminium alloy
Aluminum alloy has the advantages of light weight, corrosion resistance, good thermal conductivity, etc., and is often used in the manufacture of lightweight and high corrosion resistance requirements of metal forgings. However, its strength and plasticity are relatively low, and the price is also high.
Copper alloy
Copper alloy has excellent electrical and thermal conductivity, and is often used in the manufacture of metal forgings requiring high electrical and thermal conductivity. However, its strength and corrosion resistance are poor, and the price is higher.
Mechanical property
The mechanical property of metal forgings is an important index to measure its quality. Common mechanical properties include strength, hardness, plasticity and toughness. Different materials have different mechanical properties, it is necessary to choose the appropriate material according to the actual working conditions.
Thermal properties
Metal forgings are used in many occasions at high temperatures, so their thermal performance is also an important indicator of quality. Common thermal properties include thermal conductivity, coefficient of thermal expansion, etc. Different materials have different thermal properties, it is necessary to choose the appropriate material according to the actual working conditions.
Physical stability
Hardware forgings may be affected by physical factors, such as temperature, pressure, etc., during long-term use. Therefore, its physical stability is also an important indicator of quality. Common physical stability includes corrosion resistance, wear resistance and so on. Different materials have different physical stability, it is necessary to choose the appropriate material according to the actual working conditions.
Special performance
In addition to the above conventional properties, some special properties are also important indicators to measure the quality of hardware forgings. For example, anti-friction, anti-wear, easy cutting and other properties, need to choose the right material according to the actual working conditions.
The material selection and performance characteristics of metal forgings are important indicators to measure their quality. Different materials have different characteristics and scope of application, it is necessary to choose the appropriate material according to the actual working conditions. In the future, with the continuous progress of science and technology and the continuous development of industry, new materials and technologies will continue to emerge, and the material selection and performance characteristics of hardware forgings will be further improved and improved. At the same time, with the continuous improvement of environmental protection and energy awareness, the concept of environmental protection, energy saving and sustainable development will also run through the material selection and manufacturing process of metal forgings.
