How to choose the material when doing mechanical design
Analysis of the advantages and disadvantages of this material, and then in the mechanical design manual can be found in the application of materials such as high-quality steel:
Usually in the design, the need to refer to similar products using the material, first rough classification: such as metal (ferrous metals, nonferrous metals, alloys, stainless steel, rare metals ...), non-metallic (rubber, plastic, wood,
New materials research and the emergence of materials has always been a cutting-edge science and technology disciplines.
Casting, welding, etc.), the price and source of the material, the physical and chemical properties of the material (temperature, life, corrosion resistance, severe, heat transfer performance, etc.), so this is a very broad topic,
It is difficult to use a few words to make it clear, but the principle is to first consider its strength (including toughness, elongation, hardness and other mechanical properties of materials), processing performance (cutting, heat treatment,
