Import Brass Customized Cnc Precision Machining Parts — Buy in wholesale FOB from Supplier in China

Lianggu produces brass customized CNC precision machining parts from its facility in Dongguan, Guangdong, serving buyers who need dimensional accuracy in turned or milled brass components. The parts are machined from brass bar stock on CNC lathes and mills, with tolerances typically held to IT8-IT10 grade depending on geometry and batch size. Surface finishes include as-machined, brushed, or barrel-polished, with thread forms and bores cut to customer drawings. The brass alloy used is typically free-machining brass (CuZn39Pb3 or C36000 equivalent), chosen for its 100% relative machinability rating and chip-breaking characteristics.

Brass offers natural corrosion resistance in water, fuel, and low-salinity environments, with thermal conductivity around 120 W/m·K and good solderability. Typical hardness for annealed free-machining brass is 80-90 HV, rising to 140-160 HV in the half-hard condition. Lianggu's process covers turning, milling, drilling, threading, and secondary operations such as knurling or cross-hole drilling. Parts can be supplied with passivation or oil coating for oxidation protection during transit. Standard dimensional inspection uses calipers, micrometers, and thread gauges; CMM verification is available for tighter tolerances.

Primary applications include pneumatic valve bodies, electrical connector housings, fluid manifold blocks, instrument bezels, and mechanical couplings. Buyers span automotive tier-2 suppliers, industrial automation firms, medical device contract manufacturers, and commercial plumbing OEMs. Lianggu lists FOB and CIF as available Incoterms, with MOQ and lead time to be confirmed directly with the supplier. Buyers should provide 2D drawings with GD&T callouts, or 3D models in STEP or IGES format, to receive accurate quotations.

Lianggu operates from Changan Town, Dongguan, wholesaledistrict, Guangdong Province, a region with dense CNC machining infrastructure and rapid access to Shenzhen Port. The supplier address is Xinger Road 228, Dongguan 523000. Lianggu carries a harbor-level trust tier on its marketplace profile. The response rate is recorded at 0.00% with an average response time of 0 hours, indicating no recent inquiry activity or incomplete profile engagement. Buyers should treat initial contact as unverified and request direct communication to assess responsiveness.

The listing presents Lianggu as a source for OEM/ODM brass CNC parts with customization capability, but does not state factory size, year of establishment, revenue, or specific client references. No ISO 9001 or SGS certificate numbers are provided in the extractable data, and any certification claims should be verified directly with documentation. Buyers are advised to conduct a supplier capability audit, including sample evaluation, before committing to production orders.
