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.
