Reliable High Purity Copper Powder Manufacturer Sagwell
2026-07-27
With booming development of high-end industries including electronics, Powder Metallurgy, additive manufacturing and chemical catalysis,Copper powder, ultrafine copper powder and high purity copper powder serve as core conductive raw materials with surging global demand. Thousands of manufacturers and R&D institutions are searching for reliable factories producing ultrafine copper powder with mature technology, stable quality and customizable particle sizes. Among all suppliers, Sagwell stands out as a well-recognized manufacturer of pre-alloy powder and high purity ultrafine copper powder with decades of mass production experience and comprehensive R&D system.
1. Core Capabilities of a Qualified Factory Producing Ultrafine Copper Powder
When purchasing high purity copper powder and ultrafine copper powder, buyers mainly evaluate four key strengths that distinguish premium manufacturers from small workshops:
- Mature production technology: Chemical reduction and water atomization are mainstream processes. Chemically produced ultrafine copper powder features high sphericity, excellent flowability and narrow particle size distribution, perfectly suited for precise electronic paste;
- Strict purity control: High-end applications require copper content ≥99.5% with ultra-low impurities to guarantee stable electrical and thermal conductivity;
- Complete product portfolio: Cover micron & submicron grades, matching mesh sizes like 3000 mesh and 800 mesh for diverse demands;
- Full quality control & technical service: In-house R&D labs, automatic production lines, customized formula adjustment and on-time after-sales support.
Most small workshops only produce low-purity coarse copper powder with uneven particle sizes and poor flowability, failing to meet strict standards of electronics, aerospace and new energy sectors. As a large-scale factory producing ultrafine copper powder, Sagwell implements standardized control over raw materials, production and inspection to fully satisfy high-end manufacturing procurement requirements.

Two Main Grades of Ultrafine Copper Powder
1. F2-Cu Micro Ultrafine Copper Powder (3000 Mesh)
F2-Cu is Sagwell's best-selling ultrafine copper powder, manufactured via chemical reduction with D50 particle size 4-6 μm and Cu purity ≥99.5%. The spherical particles feature excellent flowability. Applications: Electronic conductive paste, MIM metal injection molding, additive manufacturing, superhard material production, widely adopted in electronic manufacturing.
2. X-Cu High Purity Copper Powder (800 Mesh)
X-Cu belongs to X-series high purity copper powder, chemical-process near-spherical powder with Cu content over 99.7% and D50 15-20 μm, featuring good dispersion and anti-oxidation performance. Applications: Diamond tools, ceramic & marble processing, chemical catalysts, anti-corrosion conductive coatings, electronic component filling.
Besides these two grades, Sagwell also supplies F1/F3/F4/F5/F6 and X1-Cu ultrafine copper powder covering particle sizes from 2 μm to 20 μm, with customized purity and particle size available.

5. FAQ
Q1: What is the difference between ultrafine copper powder and ordinary copper powder?
A: Ultrafine copper powder refers to copper powder with particle size under 20 μm, featuring larger specific surface area and stronger conductivity. High purity copper powder focuses on Cu content ≥99.5% with minimal impurities. Sagwell’s products meet both ultrafine and high purity standards simultaneously.
Q2: How to choose between F2-Cu and X-Cu?
A: Select F2-Cu (4-6 μm ultrafine size) for precision electronic paste and miniature MIM parts; choose X-Cu (15-20 μm high purity) for diamond tools, catalytic coatings and large component filling.
Q3: Does the factory provide free samples for testing?
A: Yes. Contact our customer service to request free samples of ultrafine copper powder and high purity copper powder for lab performance verification.
