MIM Powder
JINGYE manufactures fine MIM powder for precision metal injection molding of stainless steel, high-strength steel, cobalt-chromium alloy and soft magnetic components. Our metal injection molding powder range includes MIM-304L, MIM-316L, MIM-17-4PH, MIM-304 Hardened, proprietary LD-G19 high-strength steel, F75 Co-Cr-Mo alloy and FeSiCr soft magnetic powder.
Each MIM metal powder is developed around controlled chemical composition, fine particle size distribution, high tap density, low carbon and oxygen content, and stable batch-to-batch processing. JINGYE also provides feedstock preparation and debinding and sintering support for selected grades, connecting powder production with actual MIM process requirements.
Material selection depends on the required corrosion resistance, strength, hardness, ductility, polishability, magnetic performance and heat-treatment condition of the finished component. The following MIM powder grades cover applications ranging from polished electronic parts to high-strength industrial structures.
| MIM Material | Performance Focus | Typical Components and Applications |
|---|---|---|
| MIM-304L | General corrosion resistance, high ductility and good surface finishing performance | Consumer electronics, watch components, decorative hardware and general precision parts |
| MIM-316L | Improved resistance to pitting and chloride corrosion, high ductility and polishability | Medical instruments, watch cases, SIM trays, camera supports, valves and fittings |
| MIM-304 Hardened | Microalloyed 304-based grade combining corrosion resistance with higher strength and hardness | Scratch-resistant decorative parts, electronic connectors and precision equipment components |
| MIM-17-4PH | Precipitation-hardening stainless steel with high strength, hardness and corrosion resistance | Automotive parts, medical instruments, tools, fasteners and structural components |
| MIM-LD-G19 | Proprietary ultra-high-strength maraging steel with heat-treated tensile strength of at least 2,000 MPa and yield strength of at least 1,900 MPa | High-load hinges, aerospace structures, performance automotive parts and high-strength industrial parts |
| MIM-F75 Co-Cr-Mo | High corrosion resistance, wear resistance, strength, polishability and non-magnetic performance | Medical components, premium watch parts, precision automotive parts and corrosion-resistant hardware |
| FeSiCr Soft Magnetic Powder | High permeability, high inductance, magnetic saturation and electrical resistivity | Molded inductors, metal magnetic powder cores, power converters and electronic control systems |
A suitable metal injection molding powder must support feedstock preparation, mold filling, debinding, sintering and dimensional control. Powder chemistry alone does not determine MIM performance. Particle distribution, tap density, morphology and interstitial elements also affect powder loading, feedstock rheology, shrinkage and final part properties.
JINGYE produces fine powder distributions matched to MIM feedstock preparation. Standard stainless steel and alloy grades typically use micron-scale D10, D50 and D90 controls, while grade-specific particle distributions are provided on individual product data sheets. Customized distributions can be evaluated according to the binder system, molding equipment and target sintered properties.
Near-spherical particle morphology and controlled size distribution support higher tap density and stable powder loading. This helps maintain consistent feedstock preparation and predictable shrinkage during debinding and sintering. JINGYE evaluates tap density together with particle morphology rather than treating either value as an isolated specification.
Carbon and oxygen can influence sintering behavior, phase stability and final mechanical properties. JINGYE controls these elements during MIM metal powder manufacturing and can provide testing data for the relevant production stage. Finished-part chemistry may change during debinding and high-temperature sintering, so powder and sintered-part results are evaluated separately.
Repeatable chemical composition, particle distribution and physical properties reduce the need for frequent feedstock or sintering adjustments. Production lots can be evaluated for particle size, tap density, flow behavior, morphology and oxygen-nitrogen-hydrogen content according to the agreed specification.
JINGYE supplies MIM alloy powder and supports established feedstock formulations for selected materials, including 304L, 316L, 17-4PH, high-strength steel and other qualified alloys. Feedstock support can cover powder-binder matching, melt flow rate, green density, tooling factor and expected sintering shrinkage.

As a specialized MIM metal powder manufacturer, JINGYE combines alloy preparation, water-gas combined atomization, particle classification, screening and powder testing. The manufacturing route is adjusted according to the alloy system, target particle distribution and downstream molding requirements.
1. Alloy preparation: raw materials are prepared to the specified chemical composition.
2. Melting and atomization: controlled atomization converts the alloy melt into fine particles.
3. Classification: powder is separated and screened into the required particle range.
4. Powder testing: chemistry, particle size, morphology, tap density and interstitial elements are evaluated.
5. Feedstock verification: selected grades can be compounded and tested through molding, debinding and sintering.
6. Packaging and traceability: approved lots are identified and packed for storage and shipment.
Testing equipment includes direct-reading spectroscopy, laser particle size analysis, scanning electron microscopy, oxygen-nitrogen-hydrogen analysis, Hall flow testing and tap density measurement. Additional information is available on our Material & Quality.
JINGYE operates metal powder production together with in-house feedstock preparation, injection molding, debinding, vacuum or protective-atmosphere sintering and finished-part inspection. This provides practical feedback on powder loading, mold filling, shrinkage, density and mechanical performance before a material moves into recurring production.
Our MIM powder products support precision manufacturing in:
JINGYE can evaluate non-standard chemistry, particle size and physical property requirements. Custom development is based on the target component, required mechanical or magnetic performance, binder system, debinding method, sintering atmosphere, dimensional tolerance and planned production volume.
Material selection can also be supported when an existing grade does not provide the required balance of corrosion resistance, strength, hardness, ductility or magnetic performance.
MIM powder is a fine metal or alloy powder developed for Metal Injection Molding, also written as Metal Injection Moulding. It is mixed with a binder to produce moldable feedstock, then formed, debound and sintered into dense metal components.
MIM-316L is suited to components requiring high ductility, polishability and resistance to chloride corrosion. MIM-17-4PH is more appropriate when higher strength and hardness are required and post-sintering aging heat treatment is acceptable.
Yes. In addition to MIM metal powder, JINGYE has developed feedstock systems for several stainless steel and high-strength alloy grades. Availability and process parameters depend on the selected material and molding system.
Yes. JINGYE can evaluate customized particle distributions and alloy compositions according to the required feedstock behavior, sintered properties and production volume.
Provide your target alloy, component application, binder or feedstock system, required particle distribution, sintered properties and estimated annual usage. JINGYE will recommend a standard grade or evaluate a custom metal injection molding powder specification.
