In fields such as mechanical processing, medical devices, and aerospace manufacturing, choosing the right material often determines the performance and lifespan of the product. The three common materials - stainless steel, aluminum alloy, and PEEK - each have their own advantages and applicable scenarios. How to make the choice? This article will help you quickly understand.
Stainless steel is widely used in structural components and medical devices due to its excellent corrosion resistance and strength. It is suitable for environments with high temperatures, high humidity or high requirements for strength. However, its processing is rather difficult, and the processing time and cost are also relatively high.
Aluminum alloy is renowned for its light weight, fast heat conductivity and ease of processing. It is suitable for applications such as aviation, automobiles, and electronic equipment where weight and heat dissipation are critical. Although its strength is not as good as that of stainless steel, it offers rich surface treatments, high cost-effectiveness, and faster processing efficiency.
PEEK (Polyetheretherketone) is a high-performance engineering plastic with excellent heat resistance, chemical corrosion resistance and insulation properties. It is commonly used in medical implants, electronic components and precision mechanical parts. The drawback is that the material cost is relatively high and the processing equipment requirements are also quite demanding.
Overall:
Choose stainless steel for its high strength and corrosion resistance.
Focus on lightweight and cost-effectiveness by choosing aluminum alloy;
For precision parts that require high temperature resistance and chemical stability, PEEK is the ideal choice.
Different materials are suitable for different scenarios. When choosing materials, not only the performance is considered, but also the actual application and budget should be taken into comprehensive account.
