Products classified under HTS 7205.29.00.00
Iron Powder for 3D Metal Printing
Finely milled iron powder used in selective laser sintering (SLS) for additive manufacturing of metal parts. Classified under HTS 7205.29.00.00 as powders of iron not meeting specific alloy definitions in Chapter 72 notes. Particle size typically 15-45 microns for optimal layer fusion.
Atomized Steel Powder for Sintered Brake Pads
Water-atomized low-alloy steel powder used in powder metallurgy for automotive brake pad production. Falls under HTS 7205.29.00.00 as 'other' iron/steel powders not meeting high-strength or tool steel definitions. Typical composition: 0.5% C, balance Fe with trace elements.
Reduced Iron Powder for Welding Electrodes
Hydrogen-reduced iron powder serving as flux carrier in coated welding electrodes. Classified under 7205.29.00.00 due to high purity (>99% Fe) and spherical morphology from reduction process. Particle size range: 45-150 microns for optimal coating adhesion.
Carbonyl Iron Powder for Microwave Absorbers
Ultra-pure carbonyl process iron powder (<0.1% impurities) used in radar-absorbing materials and magnetic composites. Particle size 3-10 microns enables high surface area for EM absorption. HTS 7205.29.00.00 as other iron powder not meeting alloy definitions.
Water Atomized Steel Powder for MIM Feedstock
Water-atomized 316L stainless substitute powder for Metal Injection Molding (MIM) of precision components. While stainless-like composition, classified as 'other' steel powder under 7205.29.00.00 if not meeting exact stainless criteria. 15-45 micron size for MIM processing.
Spiegeleisen Powder for Specialty Castings
High-manganese spiegeleisen powder used as master alloy addition in ductile iron foundries. Contains 20-30% Mn, 4-6% C fitting spiegeleisen definition. Ground to 100-200 micron for injection molding into ladles.
Iron Powder for Powder Metallurgy Gears
Commercially pure iron powder for press-and-sinter gear production in automotive transmissions. Density 6.8-7.2 g/cc after sintering, annealed for machinability. Standard -100/+325 mesh size for gear compaction.
High-Purity Iron Powder for Magnetic Cores
99.9% pure iron powder insulated with phosphate coating for soft magnetic composite cores. Used in electric motor rotors and inductors requiring low hysteresis loss. 100-200 micron particles post-compaction.
Steel Powder for Thermal Spray Coatings
Low-carbon steel powder for HVOF thermal spray restoration of wear parts. Irregular morphology from crushing, 15-45 micron optimal for coating density. Provides corrosion/wear resistance on industrial components.
Iron Powder for Friction Materials
Copper-free iron powder for automotive friction plates and clutch facings. Provides heat dissipation and wear resistance in wet clutch applications. Controlled particle size distribution for uniform mixing.
