Tungsten Alloy Rods Tungsten High Heavy Alloy W90nife W97nife

Tungsten High Heavy Alloy Description:

Material:W90-97NiFe(Magnetic)&W90-97NiCu(Nonmagnetic)
Density:16.8-18.8g/cm3

High density (up to 65% denser than Lead).

• Denser materials exist (, pure Tungsten, Gold, platinum group metals) but their use is restricted by availability, workability and cost.

• Providing mass where volume space is limited.

• Concentrated weight essential where accuracy is required in placement of mass.

• Placement of weight in situations where airflow has a significant impact.

high grade Tungsten High Heavy Alloy AMST 21014 class 3(another expression)
- Material: W90-97NiFe(Magnetic) & W90-97NiCu(Nonmagnetic)
- Density:16.8-18.8g/cm3
- Rods Size:dia(1.5 -200) x Length<500mm

Thermal Properties
High softening temperature.
Low thermal conductivity and low coefficient of expansion gives the material a high resistance to thermal fatigue.
Excellent soldering erosion resistance to molten aluminium. Strong at high temperatures with high thermal stability.

Tungsten High Heavy Alloy Mechanical Properties
High Young's modulus of elasticity. Does not creep when experiencing significant forces, unlike Lead.
Despite their strength, they remain ductile and resistant to cracking.
The hardness range of the alloys is typically 20-35 Hardness HRC.
