High Density Heavy Steel Tungsten Alloy Weighted Block for Anti Vibration with Customized Dimensions
High density heavy steel W90Ni6Fe, also known as DENSIMET distributed by Ceratizit, is primarily used by PCD and PCBN tool manufacturers as a tool body for brazing PCD-PCBN plates. In addition to tungsten steel cubes, blocks, and custom shapes, tungsten alloy bars are typically produced in batch orders.

Tungsten Heavy Alloy Characteristics
Tungsten heavy alloy uses tungsten as matrix with small amounts of nickel, iron, copper, and other alloying elements. Key characteristics include:
- High and adjustable density (~18.5g/cm³)
- Excellent absorption of high-energy radiation (1/3 higher than lead)
- Low coefficient of thermal expansion (4-6×10⁻⁶/ºC)
- Good plasticity, high strength and elasticity modulus
- Excellent machinability and weldability
- Non-magnetic properties (tungsten nickel copper alloys)
Applications
Radiation Protection and Guidance:
Due to high density (~18.8 g/cm³), excellent X-ray and gamma ray absorption capacity, and superior processability, tungsten nickel iron alloy serves as ideal material for radiation therapy collimators and protection components.
Balance Weights:
Widely used in automobile crankshaft counterweights, oil weights, security defense systems, and precision optical instruments. The non-magnetic properties of tungsten copper nickel alloy make it particularly suitable for aviation electronic systems.
