Material & Finish Options

Material Selection for Precision Sheet Metal Fabrication

Material choice fundamentally dictates performance, cost, and manufacturability in high-precision sheet metal fabrication. Selecting the optimal alloy requires balancing application demands—structural load, environmental exposure, weight constraints, and finish requirements—with production realities. At Wuxi Lead Precision Machinery, our CNC systems achieve micron-level tolerances only when material properties align with the fabrication process. This guide outlines critical considerations for aluminum, steel, and titanium, alongside essential anodizing specifications.

Aluminum alloys dominate aerospace, electronics, and transportation due to their exceptional strength-to-weight ratio and inherent corrosion resistance. Grade 6061-T6 offers excellent weldability and moderate strength for structural components, while 5052-H32 provides superior formability for complex bends and deep draws. Aluminum’s thermal conductivity aids in heat dissipation but necessitates precise laser cutting parameters to prevent warping. Its natural oxide layer offers baseline protection, yet critical applications demand enhanced surface treatment.

Carbon and stainless steel remain indispensable for structural integrity and durability. Low-carbon steel (A36, 1008) delivers cost-effective strength for enclosures and brackets but requires protective finishes like powder coating. Austenitic stainless steels (304, 316) excel in corrosive or hygienic environments—medical devices, food processing—retaining strength at high temperatures. Stainless steel’s work-hardening tendency demands optimized CNC punching and bending sequences to maintain edge quality and dimensional accuracy, a capability our multi-axis press brakes consistently deliver.

Titanium Grade 2 and 5 (Ti-6Al-4V) are critical for extreme conditions: aerospace components, marine hardware, and biomedical implants. Their unparalleled strength-to-weight ratio and immunity to saltwater corrosion justify higher material and machining costs. Titanium’s low thermal conductivity generates significant heat during cutting, requiring specialized tooling and reduced feed rates. Successful fabrication hinges on stringent process control to avoid contamination and maintain material integrity, a standard Wuxi Lead’s monitored production cells uphold.

Anodizing is the definitive surface enhancement for aluminum, transforming the natural oxide layer into a dense, corrosion-resistant, and electrically insulating barrier. Type II (sulfuric acid) anodizing provides durable protection and accepts dyes for identification. Type III (hard coat) anodizing achieves significantly thicker layers (25-100 µm) for extreme wear resistance in hydraulic systems or military hardware. Critical parameters include electrolyte concentration, temperature control, and current density—all meticulously managed in our ISO-certified finishing lines to ensure uniform coating thickness and adhesion.
