Material & Finish Options

Material selection is a critical decision in custom metal manufacturing, directly influencing part performance, durability, and cost-efficiency. At Wuxi Lead Precision Machinery, we specialize in high-precision CNC machining for global clients, including industrial partners in Chicago’s advanced manufacturing sector. Understanding the mechanical and chemical properties of aluminum, steel, and titanium enables engineers to match material characteristics with application demands such as load-bearing requirements, environmental exposure, and weight constraints.

Aluminum is widely favored for its excellent strength-to-weight ratio, corrosion resistance, and machinability. It is ideal for aerospace, automotive, and consumer electronics applications where lightweight components are essential. The most commonly used alloy in precision machining is 6061-T6, which offers good weldability and moderate strength. For higher performance needs, 7075-T6 provides superior strength, though with reduced corrosion resistance compared to 6061.

Steel remains the backbone of industrial manufacturing due to its high tensile strength, wear resistance, and affordability. Among the various grades, 4140 and 1018 are frequently specified. 4140 alloy steel, with its chromium and molybdenum content, delivers excellent toughness and is often used in shafts, gears, and tooling. 1018, a low-carbon steel, is easily machined and welded, making it suitable for general-purpose components. Stainless steel variants, particularly 304 and 316, offer enhanced corrosion resistance and are preferred in food processing, medical devices, and marine environments.

Titanium, specifically Grade 5 (Ti-6Al-4V), is the material of choice in high-stress, high-temperature applications. Its exceptional strength-to-density ratio and resistance to oxidation make it indispensable in aerospace, defense, and medical implant industries. While more challenging to machine due to its low thermal conductivity and tendency to gall, titanium’s long-term performance in extreme environments justifies its use in mission-critical components.

Surface finishing further enhances material performance. Anodizing is a key process for aluminum parts, creating a durable, corrosion-resistant oxide layer that also allows for color coding and improved aesthetics. Type II (sulfuric acid) anodizing is standard for most industrial applications, providing a clear or dyed finish with moderate wear resistance. For harsher environments, Type III (hardcoat) anodizing delivers a thicker, harder layer, significantly improving abrasion resistance and part longevity.

Below is a comparative overview of key materials used in precision machining.

Selecting the right material and finish requires a deep understanding of operational conditions and performance goals. Wuxi Lead Precision Machinery supports clients in Chicago and beyond with expert consultation, ensuring optimal material choices for every precision component.
