Brass CNC machining parts, made of brass and using precision machining technology, can meet the diverse needs of global markets including Europe, America, Southeast Asia, and the Middle East. Whether it's the high conductivity requirements of the electronics industry or the aesthetic preferences of the decorative market, they meet international certifications while ensuring stable quality and efficient delivery, making them a core competitive product for expanding into overseas markets. Brass is a globally recognized "multi-functional alloy" that can be directly used in magnetically sensitive applications such as medical equipment and aerospace instruments, reducing current loss and thus lowering energy consumption. From an environmental perspective, Brass CNC machining parts have also gained recognition from many users. Brass is 100% recyclable, helping overseas users achieve their "green production" goals. Throughout the entire processing, the defect rate per million parts is less than 300, far exceeding the industry average, meeting the procurement needs of large retailers in Europe and America and ensuring a high degree of consistency in performance and dimensions for each batch of products.

 

 

Brass CNC machining parts are typically custom-made, with material selection, structure, and dimensions all produced according to blueprints. The composition of the brass directly affects the applicable scenarios of the parts; therefore, overseas users pay close attention to the composition and basic mechanical properties. Below, we provide a detailed introduction to common free-machining brass materials, hoping to assist you in your procurement.

Core components: Cu: 57%~60%, Pb: 2.5%~3.7%, Zn: balance;

Machining processes: Turning, milling, diamond tapping;

Tensile strength: ≥420 MPa;

Elongation: ≥15%;

Electrical conductivity: 28%~32% IACS;

Density: 8.4 g/cm³;

Machining accuracy: Brass CNC machining parts are classified into different accuracy levels: Standard accuracy: dimensional tolerance range ±0.01~±0.05 mm, flatness ≤0.02 mm/m, coaxiality ≤0.03 mm, surface roughness 1.6~3.2 μm; Precision grade: dimensional tolerance range ±0.005~±0.01 mm, flatness ≤0.01 mm/m, coaxiality ≤0.01 mm, surface roughness 0.4~1.6 μm; Ultra-high precision grade: dimensional tolerance range ±0.001~±0.005 mm/m. mm, flatness ≤0.005 mm/m, coaxiality ≤0.003 mm, surface roughness 0.1~0.4 μm.

Many users have questions during the procurement of Brass CNC machining parts, such as the surface treatment processes, commonly chromium-free passivation and ordinary passivation. Since these two processes directly affect the price, many users want to understand the differences and whether they affect the appearance. It's actually quite easy to understand. Ordinary passivation contains hexavalent chromium (Cr⁶⁺), which, while offering good corrosion resistance, does not meet EU production requirements. Chromium-free passivation, on the other hand, uses a zirconium-based process, contains no heavy metals, and meets global environmental standards. Visually, chromium-free passivation presents a pale golden yellow color, closer to the natural color of brass than ordinary passivation, making it ideal for decorative parts that retain a metallic texture. Its resistance to discoloration is 30% better than ordinary passivation. Each production process has its own performance characteristics. When customizing Brass CNC machining parts, it's advisable to discuss the surface treatment process with the manufacturer to achieve the best cost-effectiveness.
