Material & Finish Options

Material selection is a critical step in precision CNC machining, directly influencing part performance, durability, and cost-efficiency. At Wuxi Lead Precision Machinery, we specialize in high-accuracy online CNC cutting services, supporting industrial clients with expert guidance on material and finish selection. The most widely used metals in our production include aluminum, steel, and titanium—each offering distinct mechanical properties suited to specific engineering demands.

Aluminum is favored for its excellent strength-to-weight ratio, corrosion resistance, and machinability. It is particularly ideal for aerospace, automotive, and consumer electronics applications where lightweight components are essential. Grade 6061-T6 is a common choice due to its weldability and moderate strength, while 7075-T6 offers higher strength for more demanding structural uses. Aluminum’s natural oxide layer provides some protection, but for enhanced surface durability and aesthetics, anodizing is recommended.

Steel remains the backbone of heavy-duty industrial applications. Its high tensile strength, wear resistance, and affordability make it suitable for tooling, machinery components, and structural parts. We commonly machine stainless steel grades such as 304 and 316, which offer excellent corrosion resistance and are widely used in medical, food processing, and marine environments. For applications requiring extreme hardness, alloy steels like 4140 or tool steels can be precision cut to tight tolerances.

Titanium, though more challenging to machine, delivers an unmatched strength-to-density ratio and exceptional resistance to heat and corrosion. Grade 5 (Ti-6Al-4V) is the most prevalent in aerospace, defense, and medical implant manufacturing. Despite higher material and machining costs, titanium’s long-term reliability in extreme environments justifies its use in mission-critical components.

Surface finishing plays a pivotal role in enhancing functionality and appearance. Anodizing, particularly for aluminum, is a widely adopted electrochemical process that thickens the natural oxide layer, improving wear and corrosion resistance. It also allows for color coding through dye integration, supporting both branding and functional identification. Type II (sulfuric acid) anodizing is standard for decorative and protective finishes, while Type III (hard anodizing) delivers a thicker, harder coating for industrial wear applications.
