Verified industrial chemicals, gas-atomized specialty powders, and high-purity materials packaged and certified for worldwide distribution.
In modern industrial metallurgy, brass powder (copper-zinc alloy powder) occupies a pivotal position due to its unique combination of mechanical strength, electrical conductivity, corrosion resistance, and low friction coefficient. As international original equipment manufacturers (OEMs), automotive tier suppliers, and powder metallurgy (P/M) sintering facilities transition toward higher precision tolerances, China has evolved from a volume-centric producer into a technological epicenter for high-performance copper-based powders.
Engineered via advanced gas and water atomization techniques, Chinese brass powder meets the exacting metallurgical demands of industrial sintering, porous self-lubricating bearings, decorative coatings, diamond tool bonding matrices, and laser-directed additive manufacturing. Yanxatech System Industries Limited (YANXA) has spent over a decade delivering specification-led alloy powders, chemical additives, and high-purity materials, operating under stringent ISO quality management protocols with complete batch Certificate of Analysis (COA) audibility.
| Alloy Grade | Composition (Cu/Zn Ratio) | Typical Apparent Density (g/cm³) | Primary Morphology | Predominant Industrial Application |

| CuZn10 (90/10 Commercial Bronze) | Cu: 89.0 - 91.0%, Zn: Balance | 2.8 - 3.4 | Spherical / Nodular | Sintered bronze bearings, decorative cold-casting, metallic inks |
| CuZn20 (80/20 Low Brass) | Cu: 79.0 - 81.0%, Zn: Balance | 2.9 - 3.5 | Irregular / Water Atomized | Friction clutch plates, brake linings, electrical contact pads |
| CuZn30 (70/30 Cartridge Brass) | Cu: 68.5 - 71.5%, Zn: Balance | 3.0 - 3.6 | Gas Atomized Spherical | Additive manufacturing, high-ductility compacts, brazing pastes |
| CuZn40 (60/40 Muntz Metal) | Cu: 59.0 - 62.0%, Zn: Balance | 3.1 - 3.8 | Irregular to Dendritic | Diamond tooling matrix, abrasive wheels, high-wear structural parts |
China's comprehensive metallurgical supply chain offers unmistakable technical, cost, and capacity advantages for global supply chains.
Direct proximity to high-grade cathode copper and electrolytic zinc smelting hubs guarantees steady raw material access, dampening global raw market price spikes and securing uninterrupted high-volume production schedules.
Chinese facilities offer both ultra-clean inert gas atomization (yielding spherical powders with superior tap density for additive printing) and high-pressure water atomization (delivering irregular morphologies ideal for green-compact sintering).
Every single batch is validated via laser diffraction (Malvern PSD), oxygen/nitrogen determinators, and ICP-OES elemental analysis to confirm strict adherence to customer-defined Technical Data Sheets (TDS).
From legacy automotive components to advanced smart-infrastructure solutions, brass powders fulfill specialized mechanical and thermal functions.
Acts as an essential thermal stabilizer and friction modifier in commercial automotive brake pads and train clutch discs, dissipating local heat and preventing rotor scouring.
Pre-alloyed brass powder acts as an active matrix binder, gripping synthetic diamond crystals securely in stone cutting saws, grinding wheels, and core drills.
Flake and ultra-fine brass powders provide high electrical conductivity and anti-oxidation traits for electromagnetic interference (EMI) gaskets, coatings, and conductive pastes.
Next-generation spherical brass alloys specifically optimized for Binder Jetting and Laser Powder Bed Fusion (LPBF), producing customized thermal components without tooling.
