product overview
CX metal powder is a high-performance iron-based alloy powder developed specifically for additive manufacturing (3D printing) and advanced industrial applications. Its composition is based on iron (Fe), and key alloying elements such as chromium (Cr), nickel (Ni), aluminum (Al), molybdenum (Mo) are optimized and added to make it possess high strength, excellent corrosion resistance, and good thermal stability. CX powder is particularly suitable for 3D printing processes such as laser powder bed melting (SLM/DMLS) and electron beam melting (EBM), and can manufacture high-performance metal components with complex geometric structures. It is widely used in aerospace, energy equipment, medical devices, and high-end molds.
Product advantages
Excellent mechanical performance
After appropriate heat treatment, the hardness of CX powder printed parts can reach HRC 35-50, with a tensile strength exceeding 1000 MPa, while maintaining good toughness, suitable for the manufacturing of key components in high stress environments.
Excellent corrosion resistance (thanks to 11-13% Cr and 1.1-1.7% Mo), it can serve for a long time in harsh conditions such as marine environments and chemical media.
Optimized 3D printing adaptability
The powder is prepared using high-purity aerosolization (EIGA/VIGA) process, which has high sphericity, low oxygen content (<0.1%), and uniform particle size distribution (15-53 μ m), ensuring good flowability during the printing process, uniform powder spreading, and reducing printing defects.
Compared to traditional stainless steel (such as 316L) or tool steel, CX powder has lower crack sensitivity and higher printing stability during laser melting.
Widely applicable scenarios
Aerospace: Manufacturing lightweight and high-strength structural components, heat-resistant engine parts, etc.
Energy industry: suitable for oil drilling tools, corrosion-resistant components for nuclear power, etc.
Medical devices: Can be used for customized orthopedic implants (requiring biocompatibility verification).
Mold manufacturing: High hardness characteristics are suitable for injection molds, die-casting molds, etc., to improve mold life.
Manufacturing process and quality control
CX metal powder is produced using vacuum induction melting gas atomization (VIGA) technology to ensure uniform composition and extremely low impurity content. The production process strictly follows additive manufacturing metal powder standards such as ASTM F3049, and key control points include:
Particle size optimization: By screening and air flow classification, ensure that the powder meets the requirements of SLM/EBM process.
Low oxygen control: The entire process is protected by inert gas to prevent oxidation and ensure the density of printed materials.
Batch testing: Each batch of powder undergoes chemical composition analysis (OES), particle size distribution (laser diffraction), flowability (Hall flowmeter), and bulk density testing to ensure consistency.
3D Printing Process Suggestions
Recommended equipment: Suitable for mainstream metal 3D printers such as EOS M290, SLM 280, RenAM 500Q, etc.
Printing parameter optimization: It is recommended to use laser power of 200-300W, scanning speed of 800-1200 mm/s, layer thickness of 30-50 μ m, and substrate preheating (80-120 ° C) to reduce residual stress.
Post processing plan:
Heat treatment: solid solution (1000-1100 ° C)+aging (480-550 ° C) to maximize hardness and strength.
Surface treatment: Sandblasting, polishing, or PVD coating can be applied to enhance wear resistance and smoothness.
