CNC Machining Brass Alloys

High-Speed Machining
Brass has excellent machinability, sometimes referred to as 100% machinability. The mechanical properties of this alloy are high strength, high tensile strength and shear resistance. These characteristics contribute to the processing speed when using brass.

Precision Machining And Dimensional Stability
Brass is known for its dimensional stability and is also suitable for manufacturing with strict tolerances. Due to the smaller deformation coefficient and higher impact resistance, the dimensions of the brass components remain stable.

High Workpiece To Tool Compatibility
In brass CNC machining, the formation of chips is negligible, so tool wear is minimal. Generally, brass rod workpieces are the first choice for CNC machining. These workpieces are highly compatible with various CNC machining tools. Tool durability and frictionless machining can improve machining efficiency.

Higher Productivity And Profit
As a fast and precise machining process, brass CNC machining can improve machining efficiency. Brass is a relatively economical and convenient material, so it is conducive to capital investment in processing materials.

Environmental Protection
Brass is a copper alloy that can retain the chemical or physical properties of natural copper. However, some properties of this alloy have been enhanced. Therefore, the materials in this process are environmentally friendly. In addition, brass CNC machining will not inject any harmful gases or chemicals into the environment.

Easy To Process
Brass is a versatile material and easy to precision machining. Brass has good ductility and ductility, so you can get brass auto parts of various shapes, sizes and surface finishes.

Heat Resistance
Brass has high heat resistance and can make parts work normally even at high temperatures.

Corrosion Resistance
Corrosion will cause wear of parts, thereby shortening their service life. Brass parts have anti-rust properties due to the corrosion resistance of brass. This means less maintenance of these parts. It can greatly reduce the maintenance cost in the later stage.

Machined brass often comes with a natural golden surface, which could serve as a natural finish. However, depending on your brass part needs, you might want an external surface finish for your CNC brass machined parts. Below are some surface finishes available for CNC machined brass.

Polishing
This is a surface finishing process that improves the appearance of brass by first removing stock. It does this by taking out ruptured metal materials on the surface of the alloy. Honing also helps generate a cross-hatched pattern on the surface of the brass part, thus beautifying it.
Additionally, it helps guarantee the precision of the brass machined part, checking for straightness, roundness, and size.

As Machined
This means using the brass as machined without applying any external surface finish. When such brass is used, the focus is on its functionality instead of aesthetics.
However, surface finish often provides an added layer of protection, so using brass as machined could reduce its life span, as the risk of damage is considerably higher.

Powder Coating
This surface finish involves coating the surface of custom brass parts using the free-flowing dry powder.
Powder coating as a surface finish is highly beneficial as it helps improve the corrosion resistance of brass, durability, and longevity.

Electroplating
Brass with this surface finish appears smoother and glossier than their counterparts. The process involves using electrolysis to bind another metal's molecules to the brass's surface. Other metals used for this process include aluminum, stainless steel, etc. Brass is generally considered to be electroplated with chrome, zinc, silver, or gold.
