If you work in civil, marine, or heavy equipment, you’ve probably heard murmurs about ลูกปัดเหล็กหมู/น้ำหนักถ่วงแร่เหล็ก. To be honest, the buzz is warranted: buyers want dense, predictable ballast with sensible costs and a clean paper trail.
This material, sourced from Lubai Mountain Village, South Yanchuan, Lingshou County, Shijiazhuang City, Hebei, China, has been trending for counterweights in cranes, forklifts, wave-energy prototypes, and even precision gym equipment. Many customers say what matters most is simple: stable density, consistent mesh, and on-time delivery. I’d add QC transparency to that list.
In short: high-density iron media used as ballast or counterweight. The product comes as powder or particles (10–2000 mesh), color black. The supply chain for ลูกปัดเหล็กหมู/น้ำหนักถ่วงแร่เหล็ก is maturing, and—surprisingly—spec documentation has caught up with global project demands.
| Property | Typical value/range | Notes |
| Particle size | 10–2000 mesh | Custom sieving per ISO 3310-1; ASTM E11 equivalency |
| Total Fe | ≈ 60–95% | Varies by grade (ore vs. pig-iron beads) |
| Bulk density | ≈ 3.8–5.0 g/cm³ | Real-world use may vary with gradation |
| Moisture | ≤ 0.5% | As shipped; sealed bags or bulk liners |
| Hardness (Mohs) | ≈ 4.5–6.0 | Depends on matrix and cooling |
Service life: for fixed ballast, essentially multi‑decade; for mobile counterweights, it’s more about bag integrity than media degradation.
Customer note: “We swapped to ลูกปัดเหล็กหมู/น้ำหนักถ่วงแร่เหล็ก at 0.3 mm avg. mesh—weight spec held within ±1.5% after a year outdoors.” It seems the low moisture and sizing control help a lot.
| Vendor | Traceability | Mesh options | QC docs | Lead time |
| Baifeng Mining | Mine-to-bag origin listed | 10–2000 mesh; custom blends | ISO/ASTM test sheets attached | ≈ 7–15 days |
| Regional Trader A | Partial | Limited SKUs | Basic COA | ≈ 15–25 days |
| Import Reseller B | Unclear | Prepacked only | On request | ≈ 20–35 days |
Custom mesh gradations, oil-coated anti-corrosion packs, and low-silica blends are common. A recent lot I reviewed showed: Fe 92.1%, SiO₂ 3.2%, moisture 0.18%, bulk density 4.7 g/cm³ (ISO 3923-1). That’s good for tight-space counterweights.
Suppliers typically reference ISO 3310-1 (sieves), ISO 3082 (sampling), ISO 3923-1 / ASTM B212 (apparent density). REACH and RoHS statements are available on request—always verify for your jurisdiction.
