Product Description
LWPM's 200-300 Mesh Ultrafine Electrolytic Copper Powder is a
premium-grade metal powder designed for high-performance industrial
applications. Characterized by its distinctive orange-yellow color
and irregular particle shape, this powder boasts an exceptional
purity level of Cu ≥99.8% and an extremely low hydrogen loss (H Loss: 0.15%).
This combination of high purity and controlled particle size
distribution (200-300 Mesh) ensures excellent electrical
conductivity, sinterability, and flow characteristics. It is an
ideal raw material for advanced manufacturing processes like Metal
Injection Molding (MIM) and for enhancing the properties of various
composite materials. Sourced from a leading Chinese manufacturer
with over 30 years of expertise, our copper powder guarantees
consistent quality and reliability for your most demanding
projects.

Microwave Absorbing Materials: Used as a key component to create coatings and composites that effectively absorb electromagnetic interference (EMI).
Metal Powder Injection Molding (MIM): An excellent feedstock for producing complex, small, and precise metal parts with excellent electrical and thermal properties.
Additive for Super Hard Materials: Serves as a binder or additive in diamond tools, cutting tools, and other super-hard materials to enhance strength and thermal management.
Powder Metallurgy: Used as an additive in iron-based powder metallurgy compounds to alter conductivity, strength, and sintering behavior.
Electrical Conductors: Suitable for use in conductive pastes, paints, and composites where high electrical conductivity is paramount.
In Metal Injection Molding (MIM): The fine, irregular powder is mixed with a polymer binder to create a feedstock. This feedstock is then injected into a mold, similar to plastic injection molding. After molding, the binder is removed, and the part is sintered at high temperatures. The low H Loss (0.15%) is critical here, as it indicates minimal oxygen content, which prevents internal defects and ensures the powder particles fuse together densely and strongly during sintering, resulting in a high-integrity, fully metallic final part.
In Conductive Composites: When dispersed in a non-conductive matrix (like plastic or epoxy), the irregular copper particles create a continuous conductive network. The 200-300 mesh size provides an optimal surface-area-to-volume ratio, allowing for efficient particle-to-particle contact and maximizing electrical conductivity throughout the composite material.
As an Additive: In super-hard materials, the soft copper powder acts as a metallic binder that holds hard particles (like diamond or cubic boron nitride) in place. During the hot-press sintering process, the copper melts and flows, surrounding the hard grains and creating a strong, durable matrix.
Q1: What does "H Loss: 0.15%" mean and why is it important?
Hydrogen Loss (H Loss) is a measure of the reducible oxygen content on the surface of the metal powder. A low value of 0.15% indicates very high purity and low oxide content. This is vital for sintering processes, as it leads to better densification, higher final part strength, and superior electrical conductivity.
Q2: What is the difference between 200, 250, and 300 Mesh?
Mesh refers to the number of openings in a sieve per linear inch. A higher mesh number indicates a finer powder.
200 Mesh: ~74 microns
300 Mesh: ~50 microns
The choice depends on your application's requirements for surface
detail, packing density, and flow characteristics.
Q3: Can you provide customized particle size and packaging?
Yes. We offer a range of particle sizes from -80 mesh to -300 mesh. We also provide flexible packaging options, from standard 25kg bags to large 1000kg bags, and can customize according to your specific logistics and handling needs.
Q4: Are your products certified?
Absolutely. Our manufacturing processes are certified under the ISO9001:2008 quality management system, ensuring consistent and reliable product quality.
Q5: What is the origin and production capacity?
We are a leading manufacturer based in China with an annual production capacity of over 200,000 metric tons, guaranteeing a stable and scalable supply for global customers.
