1. Stainless steel crankcase: the ideal choice for high strength and corrosion resistance
Stainless steel has become the choice for crankcase applications that require extremely high mechanical properties and durability due to its strength and corrosion resistance.
Corrosion resistance: Stainless steel crankcases can resist corrosion from moisture, chemicals and high temperatures, and are particularly suitable for environments that come into contact with liquids or gases, such as water pumps or wet automotive engine systems. This material ensures a long life for the crankcase in harsh conditions and reduces the frequency of maintenance and replacement.
Strength and durability: The high tensile strength and structural stability of stainless steel make it suitable for those occasions that need to withstand greater mechanical stress and impact. Therefore, in high-strength mechanical environments, stainless steel crankcases can ensure the safe operation of the system.
Manufacturing cost and weight: Although stainless steel has performance, it is relatively heavy and has a high manufacturing cost. Therefore, in projects that require lightweight design or are cost-sensitive, choosing stainless steel may not be the option.
2. Brass Crankcase: Excellent Machinability and Moderate Strength
Brass is an alloy composed of copper and zinc. With its good machinability and moderate strength, it is widely used in products that require high-precision machining, such as fishing tackle series. Ningheng ensures the accuracy and consistency of brass crankcase in complex designs and machining through high-precision CNC machining and wire cutting processes.
Machinability: Brass has very good machinability and is suitable for machining complex geometries, making it an ideal material for parts that require high precision and high complexity. Brass crankcases are often used in products that require strict tolerances, such as parts in high-end fishing tackle or precision equipment.
Corrosion resistance: Brass has corrosion resistance, especially in humid or chemical-containing environments, and performs better than ordinary steel. Therefore, it is a common material in applications with medium strength and corrosion resistance.
Disadvantages: Although brass crankcases perform well in corrosion resistance and machinability, their strength and hardness are lower than stainless steel, making them unsuitable for applications that are subject to excessive mechanical loads.
3. Copper Crankcase: Excellent thermal and electrical conductivity
Due to its electrical and thermal conductivity, copper has an irreplaceable position in some special applications. Ningheng's copper crankcase ensures its performance in equipment such as electrical and pneumatic tools through precision mold processing and high-precision engraving technology.
Thermal and electrical conductivity: The high electrical and thermal conductivity of copper materials make it an ideal choice for electrical equipment and thermal management systems. For crankcases in power tools or pneumatic equipment, copper materials can ensure efficient heat dissipation of the system and prevent equipment damage caused by overheating.
Antibacterial property: Copper has natural antibacterial properties. In applications that need to maintain hygiene, such as medical equipment or food processing machinery, copper crankcase can effectively reduce bacterial growth and ensure the hygiene of the product.
Disadvantages: Copper has low strength and high cost, so the application of copper crankcase will be limited in situations where high strength and durability requirements are required. In addition, its relatively large weight has limited application in lightweight design.
4. Aluminum alloy crankcase: balance of lightness and strength
Aluminum alloy is widely used in a variety of industrial applications due to its lightweight, corrosion resistance and moderate strength. Ningheng's aluminum alloy crankcase uses advanced CNC machining and drilling technology to ensure precise dimensions and surface finish. Aluminum alloy crankcase is particularly suitable for weight-sensitive industries such as the automotive and power tool industries.
Lightweight design: The density of aluminum alloy is much lower than that of stainless steel and copper, but its strength can meet the requirements of mechanical applications. For automobiles and portable devices that require lightweight design, aluminum alloy crankcase is an ideal choice, which can reduce weight while maintaining mechanical strength.
Corrosion resistance: Aluminum alloy has good corrosion resistance, especially when exposed to air or humid environments. Its oxide layer can effectively protect the internal structure from further corrosion.
Processability and cost: Aluminum alloy is easy to process, relatively low cost, and suitable for mass production. Therefore, in automotive parts and power tools that need to be mass-produced, aluminum alloy crankcases often have a high cost-effectiveness.
