Specializing in Custom Brass Parts, Automobile Plastic Parts Manufacturing, and Metal Auto Components.
Modern automotive manufacturing relies on three critical component categories: custom brass parts, automobile plastic parts manufacturing, and metal auto parts. These elements work together to ensure vehicle performance, durability, and efficiency.

CNC Machining Brass
Brass is a widely used copper-zinc alloy, its composition varying depending on the zinc content and other alloying elements such as lead, aluminum, and iron. Brass possesses excellent thermal and electrical conductivity due to its copper content, while also exhibiting exceptional wear resistance. The addition of lead further enhances its machinability, making brass the easiest of all copper alloys to machine. These properties make brass widely used in CNC machining, suitable for the manufacture of various precision parts.

Copper Cylinder (Copper C260)
Copper C260 is a zinc alloy formula containing approximately 30% zinc and less than 1% lead and iron. This grade is sometimes referred to as cartridge brass, a name derived from its historical use in ammunition cartridges. Besides its use in ammunition cartridges, Copper C260 is also commonly used in components such as rivets, hinges, and radiator cores. Its excellent mechanical properties and corrosion resistance make it widely used in various industrial applications
| Tensile Strength, Yield (MPa) | Fatigue Strength (MPa) | Elongation at Break (%) | Hardness (Brinell) | Density (g/cm^3) |
|---|---|---|---|---|
95 | 90 | 65 | 54 | 8.53 |

Free-Machining Brass (Copper C360)
Copper C360, also known as free-machining brass, exhibits excellent machinability due to the alloy's relatively high lead content. This material's excellent properties lend it to outstanding performance in many industrial applications. Typical applications include gears, screw machine components, and valve components. Its excellent machinability makes Copper C360 an ideal choice for machining precision parts.
| Tensile Strength, Yield (MPa) | Fatigue Strength (MPa) | Elongation at Break (%) | Hardness (Brinell) | Density (g/cm^3) |
|---|---|---|---|---|
124 to 310 | 138 | 53 | 63 to 130 | 8.49 |
* Generalized values. For reference only. Values vary greatly depending on temper.

Like stainless steel or copper, brass generally does not require coating due to its inherent conductivity, corrosion resistance, and low coefficient of friction. However, in certain applications, such as cosmetic containers or parts exposed to the environment, a clear coating may be considered. Here are some practical surface treatment options for CNC machined brass:
The automotive industry's evolution depends on the synergy between custom brass parts, automobile plastic parts manufacturing, and metal auto parts. Understanding their unique properties, manufacturing processes, and applications helps manufacturers and designers make informed decisions for vehicle production.
