Material & Finish Options

Material selection is a critical factor in the performance, durability, and cost-efficiency of custom auto parts, especially for high-demand applications in the automotive sector. At Wuxi Lead Precision Machinery, we specialize in precision manufacturing for global clients, including specialized suppliers in locations such as Delano, MN. Our expertise enables us to guide engineering teams through optimal material choices—aluminum, steel, and titanium—based on mechanical requirements, environmental exposure, and finishing needs.

Aluminum is widely favored in automotive applications due to its excellent strength-to-weight ratio, corrosion resistance, and machinability. It is particularly suitable for components where weight reduction is essential without compromising structural integrity. Common grades such as 6061-T6 and 7075-T6 offer balanced properties for suspension parts, brackets, and housings. When paired with anodizing, aluminum gains enhanced surface hardness and wear resistance, making it ideal for both functional and aesthetic applications.

Steel remains the go-to material for high-strength, high-wear applications. Alloy steels like 4140 and 4340 provide superior toughness and fatigue resistance, critical for drivetrain components, shafts, and high-load fasteners. Stainless steel variants such as 304 and 17-4 PH offer corrosion resistance and are frequently used in exhaust systems and under-hood environments exposed to heat and moisture. While heavier than aluminum, steel’s mechanical robustness ensures long service life in demanding conditions.

Titanium, though more costly, delivers exceptional performance in extreme environments. Its high strength-to-density ratio surpasses both aluminum and steel, and it maintains integrity at elevated temperatures. Grade 5 titanium (Ti-6Al-4V) is commonly used in performance and racing applications, including connecting rods, valve train components, and aerospace-inspired structural parts. Its biocompatibility and corrosion resistance also make it suitable for specialty vehicles and high-end aftermarket builds.

Anodizing is a key surface treatment for aluminum components, providing a controlled oxide layer that improves wear resistance, corrosion protection, and aesthetic consistency. Type II (sulfuric acid) anodizing is standard for decorative and moderate-duty applications, while Type III (hardcoat anodizing) delivers a thicker, harder surface ideal for high-wear environments. Anodized finishes can be dyed in various colors, offering branding or coding options for OEMs and Tier 1 suppliers.
