High Dimensional Precision
We support customized ultra-tight tolerance production. The dimensional error can be controlled within ±0.005mm. Extra thin copper tubes, micro-diameter copper bars and ultra-thin copper sheets are all available for customized production. All sizes can be processed strictly according to your drawings.
Superior Surface Fineness
Our copper products feature mirror smooth, scratch-free surface without burrs, oxidation spots or uneven edges. We provide multiple surface treatments including polishing, pickling, passivation to achieve ultra-fine surface finish, perfectly fit precision instruments, electronic components and precision engineering parts.
Premium Raw Material
We adopt 99.99% pure copper (T2/C11000) as raw material, with excellent electrical conductivity, thermal conductivity and ductility. The material is soft and easy for deep drawing, bending, cutting and fine machining without cracking.
Custom Fine Processing Service
We offer one-stop deep processing: micro slitting, fine cutting, precision drilling, CNC turning, threading, punching and laser cutting. We can produce ultra-fine copper parts for electronics, refrigeration, new energy, medical equipment and precision machinery industries.
Stable Quality & Complete Certificates
Each batch is attached with official Mill Test Certificate. Our products comply with international standards ASTM, EN and GB. Small trial orders of ultra-fine copper materials are warmly welcomed before bulk cooperation.
Flexible Shipping Terms
We support FOB, CFR, DAP delivery solutions, and can provide full set export documents to smooth your customs clearance, including anti-dumping related consulting support.
