About The Material

Brass is an alloy of copper and zinc, especially metal material with more than 20% zinc content, which is the most commonly used metal material in cnc machining.

The color of the alloy will become lighter with the increase of zinc content, and its hardness will also increase with the increase of zinc content, and it will also become more brittle.

Brass has excellent properties for machining, such as:

Brass Alloys for CNC Machining

The most common brass alloys AT-Machining used for CNC milling or CNC turning are C260 and C360

Working with the right alloy can prove essential for successful project completion. Each option offers its own specialized benefits, so it’s wise to look into which one will be best suited for your application needs before beginning work.

Brass C260 has very good plasticity (is the best in brass) and high strength, good machining performance, easy to weld, non-stable to general corrosion, but easy to crack. Used for complex cold and deep drawing parts, such as radiator shell, conduit, bellows, cartridge, gasket, detonator, etc.

Brass C360, also known as free-cutting brass, offers superior machinability and is often used for the production of essential components such as gears, screw parts, and valve fixtures. Its excellent qualities come from its unique alloy construction which features a high concentration of lead.

CNC Machined Brass Applications

Machined brass is a beautiful and durable material that can be used for various projects. From watches to furniture and even handicrafts!
CNC machining offers almost unlimited possibilities when designing with this strong and soft metal; whether you are looking for small parts like beads or major components like entire frames, brass is a good choice for you!

Surface Finishes For CNC Machined Brass Parts

AT-Machining can provide the perfect finishing touch to your CNC machined brass parts with a range of powder coating, bead blasting, and plating options. Each finish offers its own advantages – so make sure you select the one that meets all your requirements!

Name Description
aluminum as machined As machined The machined aluminum parts are left with visible tool marks and potentially sharp edges and burrs, which can be removed upon request.
aluminum alloy beadblasted finish Bead Blasted Give the machined parts a smooth and uniform matte surface finish, thereby removing tool marks.
aluminum polished Polishing Creating a smooth and shiny surface by manually polishing in multiple directions or by applying a chemical polish treatment.
aluminum decoretive plating Decorative Chrome Plating Enhance aesthetics and durability of the cnc aluminum components.
aluminum powder coat Powder Coat Applying powdered paint to the components and then baking it in an oven, which results in a stronger, more wear- and corrosion-resistant layer that is more durable than traditional painting methods.
nickel plating Nickel Plating Nickel plating refers to the plating of a layer of nickel on a metal or some non-metal by electrolysis or chemical methods make the workpiece has better corrosion resistance and wear resistance
gold plating Gold Plating From protection against corrosion to increased conductivity and durability, gold-plated connectors offer numerous advantages.
silver plating Silver Plating Silver plating is a process of coating materials with silver, which is also known as electrolysis. Make the workpiece better Conductivity,Corrosion resistance,Wear resistance,Durability,Solderability

CNC Machining brass FAQs

Is the hardness and strength of the material easier to CNC machine?

The higher the hardness and strength of the material, the higher the cutting force, the higher the cutting temperature, the faster the tool wears, so the worse the machinability of cutting. It is not the lower the hardness of the material, the easier to machine. Some metals such as iron, copper and other hardness is low, but the plasticity is very good, but also not easy to machine. The brass C360 with moderate hardness is easier to process. In addition, the appropriate increase in the hardness of the material is conducive to obtaining a better processing surface quality

What general tolerances can AT Machining achieve?

General Machining Tolerances on metal to +/- 0.005" (+/- 0.127 mm) following ISO 2768 unless otherwise specified. Plastics and composites will be +/- 0.010”(+/- 0.254 mm).

What precision tolerances can AT Machining achieve?

Precision Machining Tolerances down to ±.0002" (0.005mm). AT can manufacture and inspect to tight tolerances per your drawing specifications.

Is brass easier to machine than aluminum?

Yes Brass is easier to cnc machining to ideal part than aluminum. Free-machining brass is renowned for its superior cutting capabilities, due to the lubricating properties of lead added into the alloy. This allows less power and higher speeds during machining processes, resulting in reduced tool wear with excellent results every time.

What is brass CNC machining?

Brass is a remarkable alloy, combining the classic beauty of copper with the sturdiness and strength of zinc. Not only does this metal stand up to weathering and rust, but it's also easily machinable so you keep those production speeds high while saving on coolant costs!

Is brass easier to machine than steel?

While free machining steels are often seen as the benchmark of machinability, brass alloys have a distinct advantage when it comes to ease and efficiency in production - making them one of the most sought-after materials for machine work.
