Product Description
Product Overview
Heavy Steel Magnetic Alloy W90Ni6Fe (DENSIMET) round bars designed for precision tool manufacturing applications requiring anti-vibration properties and exceptional durability.
Primary Applications
Primarily used by PCD and PCBN tool manufacturers as tool bodies for brazing PCD-PCBN plates. Available in diameters from 6.0mm to 25.0mm with h6 tolerances and lengths of 330-600mm.
Chemical Composition
| Element | Content (%) |
|---|---|
| Nickel (Ni) | 49.0-51.0 |
| Iron (Fe) | Balance |
| Manganese (Mn) | 0.3-0.6 |
| Copper (Cu) | ≤0.2 |
| Sulfur (S) | ≤0.02 |
| Carbon (C) | ≤0.03 |
| Phosphorus (P) | ≤0.02 |
| Silicon (Si) | 0.15-0.3 |
Specialized Applications
Radiation Protection & Guidance
With high density (~18.8 g/cm³) and excellent X-ray/gamma ray absorption capacity, this alloy serves as ideal material for radiation therapy collimators and protection components.
Balance Weights
Widely used in automotive crankshaft counterweights, oil weights, security defense systems, and precision optical instruments. Magnetic properties make it particularly suitable for aviation electron systems.
Maximum Production Capacity
Maximum diameter for h6 ground tungsten alloy bars: 80mm
Tungsten Nickel Copper Alloy Properties
