Wuhan Precision Metal Stamping Co., Ltd., the material characteristics you should pay attention to in the design

Wuhan Precision Metal Stamping Parts Co., Ltd., when you design stamping parts for your own products, the metal materials you need to choose are also different for different products, different structures, and different needs. So which characteristics of metal materials need to be paid attention to first? The physical properties of metal materials mainly include density, melting point, thermal expansion, thermal conductivity, electrical conductivity and magnetic properties. Due to the different uses of machine parts, their physical performance requirements are also different. For example, aircraft parts are often made of low-density aluminum, magnesium, and titanium alloys; when designing motors and electrical parts, the conductivity of metal materials is often considered. The physical properties of metal materials sometimes have a certain influence on the processing technology. For example, the thermal conductivity of high-speed steel is poor, and low speed should be used to heat up during forging, otherwise cracks will easily occur; and the thermal conductivity of the material has a significant impact on the temperature rise of the cutting tool. For another example, tin-based bearing alloys, cast iron and cast steel have different melting points, so the selected melting equipment and casting materials are very different. The chemical properties of metal materials mainly refer to the ability to resist corrosion by various media at room temperature or high temperature, such as acid resistance, alkalinity, and oxidation resistance. For machine parts that work in corrosive media or at high temperatures, because the corrosion is stronger than in the air or at room temperature, special attention should be paid to the chemical properties of metal materials when designing such parts, and good chemical stability should be used. alloy. For example, chemical equipment, medical appliances, etc. are often made of stainless steel, while some parts of internal combustion engine exhaust valves and power station equipment are often made of heat-resistant steel.
