Bead Blasted Anodized Aluminum: Premium CNC Machined Components
Our Bead Blasted Anodized Aluminum parts are made with precise CNC cutting and high-tech finishing methods. Custom solutions with specs as tight as ±0.01 mm and response times as fast as 3 days for simple items have been what we do since 2008. Our engineering team has over 15 years of experience and works directly with you to make sure plans are the best they can be and that they can be made. We help with projects from the pilot stage to mass production, and we make sure the quality is always the same by controlling the cutting and finishing. We can make parts that work and look good for electronics, robots, and industrial uses all over the world. We can do 100% custom making and guarantee a 7-day sample turnaround.
What Makes Our Bead Blasted Anodized Aluminum Special
Standard polished aluminium is turned into high-quality parts with this surface treatment. Precision CNC tasks are the first step in the process. Then all tool marks are taken away by bead blasting. Lastly, anodising makes an oxide layer that protects the metal.
As a result? Parts that stand the test of time and look good.
You'll like a number of the benefits that the product has to offer. The matte finish hides small scratches that happen when you handle it. When aluminium is anodised, it protects against rust better than when it is bare. It also has a smooth, even appearance.
We carefully keep an eye on every step. After making sure your parts are exactly what you want, we blast them with glass beads. This makes the surface roughness even. Once you tell us what thickness and colour you want, we anodise it.
The oxide layer adds only a small amount of space—usually 5 to 25 microns, based on the type. We take this growth into account when we machine. Your finished parts exactly match what was asked for in the picture.
Materials and Finishing Options
We work with aluminum alloys chosen for your application:
- 6061-T6 provides excellent strength for structural parts
- 6063 offers superior surface finish for visible components
- 7075-T6 delivers maximum strength when you need it
Color choices include natural silver, black, gold, blue, red, and custom shades. Hard anodizing (Type III) is available when you need extra wear resistance.
The bead blasted finish creates a consistent matte appearance. This works beautifully for housings, enclosures, panels, and decorative elements.

Our Engineering-Driven Approach
You'll work directly with our engineers, not salespeople. This makes communication faster and more effective.
Our team reviews your drawings carefully. We suggest improvements for manufacturability. We recommend optimal materials and tolerances. And we solve technical challenges before production starts.
This engineering-first approach reduces errors significantly. It shortens lead times. And it often lowers your costs.
We support complex geometries and special requirements. Small-batch production? No problem. Tight deadlines? We'll make it work.
Quality You Can Trust
Every part goes through rigorous inspection. We check dimensions during and after machining. We measure anodizing thickness. We verify color consistency and surface quality.
For Bead Blasted Anodized Aluminum parts, appearance matters. We pay special attention to visible surfaces. Any defects get caught before shipping.
Material certifications are available for all raw aluminum. We comply with FDA standards for food-contact applications. Salt spray testing reports can be provided when requested.
If quality issues arise within the same month, we'll remanufacture within one week and cover shipping costs.
Applications Across Industries
Our customers use these components in many ways:
Electronics: Housings, heat sinks, control panels, and enclosures benefit from the attractive finish and corrosion protection.
Coffee Equipment: Visible parts like machine housings and decorative panels showcase the premium matte appearance.
Robotics: Structural components gain durability while maintaining precise dimensions.
Industrial Equipment: Control boxes, mounting plates, and brackets resist environmental damage.
Automotive: Interior and exterior trim pieces combine strength with visual appeal.
The uniform surface texture makes the product ideal whenever appearance and performance both matter.
From Quote to Delivery
Our process is straightforward. Send your drawings in PDF, DWG, STEP, or IGS format. Our engineers review them quickly and provide a detailed quote.
Once approved, we typically deliver samples within 7 days. Simple parts can be ready in just 3 days.
For production orders, we maintain clear communication throughout. You'll receive updates on progress. And we coordinate flexible delivery schedules.
We handle international shipping efficiently. Door-to-door service is available, especially optimized for small-batch orders. Duties and shipping can be managed together for your convenience.
