Material & Finish Options

Material Selection for High-Precision Powder Swiss-Type Machining Parts
Selecting the appropriate material is critical when manufacturing high-precision components via powder Swiss-type machining. At Wuxi Lead Precision Machinery, we specialize in delivering custom metal parts that meet exacting performance, durability, and dimensional accuracy requirements. The three most widely used base materials—aluminum, steel, and titanium—each offer distinct mechanical and chemical properties suited to specific industrial applications.
Aluminum is favored for its excellent strength-to-weight ratio, corrosion resistance, and machinability. It is particularly effective in aerospace, electronics, and medical device applications where lightweight components are essential. Powder metallurgy aluminum alloys, such as Al-6061 and Al-7075, can be processed with high precision on Swiss-type machines, producing complex geometries with tight tolerances. These alloys also respond well to secondary finishing processes, especially anodizing.
Steel, particularly alloy and stainless steel variants, delivers superior strength, wear resistance, and thermal stability. Powdered steel alloys like 316L and 17-4 PH are commonly used in high-stress environments such as automotive systems and industrial fluid control. These materials maintain dimensional integrity under load and offer excellent resistance to corrosion and high temperatures. Swiss-type machining of powdered steel enables micro-precision threading, grooving, and contouring, making it ideal for miniature mechanical components.
Titanium and its alloys, such as Ti-6Al-4V, are selected for extreme performance demands. With exceptional corrosion resistance, high strength-to-density ratio, and biocompatibility, titanium is the material of choice for critical aerospace, defense, and medical implant applications. Although more challenging to machine due to work hardening and low thermal conductivity, powdered titanium responds effectively to controlled Swiss-type processes when optimized for speed, feed, and cooling.
Anodizing as a Finishing Process
Anodizing is a key surface treatment, particularly for aluminum components. This electrochemical process enhances surface hardness, wear resistance, and corrosion protection while allowing for color coding and improved adhesion for paint primers. Type II (sulfuric acid) and Type III (hardcoat) anodizing are commonly applied, with Type III offering thicker, more durable coatings for demanding environments. Anodized finishes are fully compatible with the tight tolerances achieved in Swiss machining, ensuring that post-processing does not compromise dimensional accuracy.
Below is a comparative overview of key material properties relevant to powder Swiss-type machining:
| Material | Tensile Strength (MPa) | Density (g/cm³) | Common Alloy Forms | Typical Applications | Anodizing Compatibility |
|---|---|---|---|---|---|
| Aluminum | 310–570 | 2.7 | Al-6061, Al-7075 | Aerospace, Electronics | Excellent |
| Stainless Steel | 515–1300 | 7.9 | 316L, 17-4 PH | Medical, Automotive | Limited (not typical) |
| Titanium | 900–1170 | 4.5 | Ti-6Al-4V | Defense, Implants, Aviation | Poor (requires special methods) |
Material and finish selection must align with functional requirements, environmental exposure, and lifecycle expectations. At Wuxi Lead Precision Machinery, we support clients in choosing the optimal combination of powder metal composition and surface treatment to ensure performance, reliability, and cost-efficiency in every custom component.

This phase eliminates 95% of potential production errors at the source.
Prototyping: Validating the Process
A functional prototype is produced on the designated production Swiss lathe under controlled parameters. We utilize in-process probing and CMM verification to measure critical features against the validated design model. Material properties of sintered powdered metals—such as density consistency and microhardness—are rigorously tested. Any deviations trigger immediate process recalibration. This stage confirms tool life projections, cycle time accuracy, and surface finish requirements, establishing the exact parameter set for mass production. Only when all specifications are met with zero non-conformities does the process advance.
