CNC Machined Black-Anodized Aluminum Parts with Excellent Abrasion Resistance

With 15+ years in custom CNC precision machining services, JINGXIN has honed its skills in aluminum component manufacturing. Our work with aluminum includes specialized processes like black anodization, which enhances both the material’s natural durability and its resistance to wear—making these parts ideal for high-use applications. Located in Dongguan City, China, our professional team adopts rational manufacturing processes, targeted solutions, and meticulous workmanship to supply high-quality one-stop custom CNC precision machined parts. These include aluminum components (finished with black anodization for superior abrasion resistance) alongside parts made of stainless steel, iron, and other materials.

We Focus on:

Custom non-standard CNC precision machining services & milling parts, with deep experience in aluminum components that benefit from black anodization. These parts excel in scenarios where both toughness and a polished look matter, such as:

• Automation equipment housings (standing up to daily scrapes and impacts)

• Electronic device mounting brackets (withstanding frequent assembly and disassembly)

• Medical equipment panels (maintaining appearance through repeated sterilization)

• Industrial control knobs (resisting wear from constant handling)

Our product scope also covers fittings, valves, hydraulic components, electric motor parts, transmission and pump parts, sprocket wheels, wear parts on packing machines, and electronic and medicinal pieces.

Our Advantage:

1.Advanced Equipment: We operate a world-class facility equipped with a variety of precision CNC machines (Brother, HAAS, Mazak), vertical milling centers, and precision milling and turning lathes (including 3-axis, 4-axis, and 5-axis models). Our equipment is fine-tuned for aluminum machining—high spindle speeds create smooth surfaces that serve as an ideal base for black anodization, while sharp cutting tools minimize imperfections that could affect the finish. Our in-house anodization line ensures consistent oxide layer formation (typically 8-12μm thick), a key factor in boosting abrasion resistance.

2.Complete Machining Capability In-House: We adhere to the ISO 2768-F/M machining standard for tolerances, producing parts in a wide range of sizes and complexities—from small aluminum knobs to large equipment housings. For parts receiving black anodization, we add post-process checks: pencil hardness tests (consistently achieving 2H or higher, indicating strong wear resistance) and adhesion tests to ensure the black finish stays intact under stress. Maximum CNC milling capability is detailed in the list below.

3.Raw Material: We guarantee 100% compliance of all materials with RoHS standards and your design specifications. For aluminum parts destined for black anodization, we select grades like 6061 and 7075—alloys that respond well to the anodizing process, developing a uniform black finish while retaining structural strength. The combination of these alloys and their anodized layer results in excellent abrasion resistance. We provide material certificates, SGS reports, and anodization performance data (including wear test results) upon request. Our material range also includes steel, stainless steel, titanium, and engineering plastics (e.g., PEEK, PC, POM); more details refer to the list below.

4.Order Quantity: We accept orders starting from 1 unit, supporting both short-run precision CNC milling & turning and large-volume production—whether you need a small batch of custom black-anodized brackets or mass-produced aluminum panels.

5.Quick Turnaround: We provide quotes within hours and fast delivery in days, backed by a skilled and professional R&D team. Even with the added step of black anodization (which enhances wear resistance), we optimize workflows to keep production on schedule.

6.Our Customers: Our customers are from the EU and North America, many in industries like automation, electronics, and medical equipment. They value our aluminum parts for their ability to withstand daily use without losing their finish—a benefit of the black anodization process we’ve refined over years.

Quality Assurance:

What we do to ensure you receive high-quality CNC Precision Machining parts from JINGXIN: We declare here that we will be responsible for our precision machined parts at all times—especially for aluminum components with black anodization, where the finish’s durability directly impacts product longevity.

1.100% inspection before shipping: For black-anodized aluminum parts, we conduct specialized tests—including abrasion resistance checks (using a Taber abraser), finish uniformity assessments, and dimensional verification (accounting for the anodization layer). An inspection shipment report for each piece of precision CNC milling part is available. We implement ISO quality control throughout production, from aluminum material checks to final anodization inspection.

2.We have served Volvo Auto Corp since 2016 as an approved precision CNC milling company in China (supplying high-precision auto parts), and we’ve also partnered with EU-based electronic equipment brands for 4+ years—providing black-anodized aluminum parts that maintain their appearance and wear resistance, with no complaints to date.

3.In case any precision machined part (including black-anodized aluminum components) is outside tolerance, shows poor abrasion resistance, or has finish defects, we will remake and deliver them as fast as we can, 100% free from our side.

4.Over the past years, JINGXIN CNC Milling Company has manufactured thousands of precision CNC machined components—including tens of thousands of aluminum parts finished with black anodization. The 99.9% satisfaction feedback (particularly about how well these parts hold up to daily use) drives us to keep refining our processes and delivering quality parts.
