Brass Machining Surface Finish Options
We provide various surface treatment solutions to enhance the functionality and aesthetics of precision brass components.
As Machined
Smooth surface with visible tool marks. Surface roughness (Ra) 6.3-12.5 μin. Cost-effective solution for functional parts.
Polishing/Buffing
The bright golden appearance is a highlight. Surface roughness (Ra) 8-16 μin. Excellent for high-end decorative components.
Brushed/Satin
Features directional grain textures. Effectively masks fingerprints and minor scratches. Ideal for premium hardware.
Nickel Plating
Offers superb rust prevention and durability. Available in bright and matte finishes to suit different design needs.
Chrome Plating
Highly reflective with high gloss. Features exceptional hardness and scratch resistance for heavy-duty applications.
Passivation
A chemical treatment that enhances corrosion resistance while preserving the original metallic aesthetic of the brass part.

Brass is one of the easiest metals to machine, making it great for CNC machining. Brass also has other very useful properties making it great for different industries such as plumbing, electrical and medical. Overall, it has great durability. It being so versatile and easy to work with is what makes it such a common metal for parts in a wide variety of applications. CNC machined Brass parts begin as a raw piece of metal which is cut down bit by bit to create a desired shape or object. This process is done most accurately with a CNC (Computerized Numerical Control) machine which can produce almost any three dimensional object designed via CAD (Computer Aided Design) software.
Brass machined parts
We offer a complete CNC machining service for brass parts and can produce complex Brass parts in Brass C360. Brass parts are great for applications that require high strength, corrosion resistance, a low friction coefficient, electrical conductivity and overall versatility. We work with almost every kind of CNC mill and turning center, and are able to machine whatever you need, from simple, ‘as-machined’ workholdings to complex, organic geometries with tight tolerances. When creating Brass machined parts with us, you can apply up to 6 different post-processing/surface finishing options including bead blasting, powder coating, smooth machining and polishing.
