Material Selection Guide for Precision CNC Machining – Wuxi Lead Precision Machinery

Selecting the right material is critical in custom metal manufacturing, especially for high-performance applications in aerospace, medical, automotive, and industrial equipment sectors. At Wuxi Lead Precision Machinery, we specialize in precision CNC machining services tailored to your engineering requirements, ensuring optimal performance, durability, and cost-efficiency. Our expertise includes working with key engineering metals—aluminum, steel, and titanium—each offering unique mechanical properties and compatibility with surface treatments such as anodizing.

Aluminum is widely favored for its excellent strength-to-weight ratio, corrosion resistance, and machinability. It is ideal for applications requiring lightweight components without sacrificing structural integrity. Among the most commonly used grades are 6061 and 7075, with 6061 offering good weldability and moderate strength, while 7075 delivers higher strength, suitable for demanding aerospace environments. Aluminum is particularly well-suited for anodizing, a process that enhances surface hardness and wear resistance while allowing for color coding and improved aesthetics.

Steel, particularly stainless steel grades such as 303, 304, and 17-4 PH, provides superior strength, durability, and resistance to high temperatures and corrosion. Stainless steels are essential in medical devices, food processing, and marine applications where hygiene and long-term reliability are paramount. While steel cannot be anodized like aluminum, it benefits from alternative surface treatments such as passivation, electropolishing, or coating to enhance performance.

Titanium, notably Grade 5 (Ti-6Al-4V), offers an exceptional strength-to-density ratio and outstanding resistance to corrosion, especially in saline or acidic environments. Its biocompatibility makes it a preferred choice for medical implants and aerospace components. Though more challenging to machine due to its low thermal conductivity and tendency to gall, titanium’s performance in extreme conditions justifies its use in mission-critical applications.
