Products Description
Tungsten-based high specific gravity alloys are alloys composed of nickel and copper added to tungsten and other metallic elements added on top of that. These alloys are non-ferromagnetic and have relatively good thermal conductivity, and are often used in special applications, such as gyroscope rotors and other parts of devices and instruments that work under magnetic fields; electrical contacts of high-voltage electrical switches and some electrodes for electrical processing.
Tungsten-nickel-copper high specific gravity alloy material is a class of alloy composed of tungsten as the base (W content 85% to 99%) with the addition of Ni, Cu, Co, Mo, Cr and other elements.
Features:
1. High specific gravity: general specific gravity of 16.5 to 18.75g/cucm.
2. High strength: tensile strength of 700 to 1000 MPa.
3. High ray absorption capacity: its capacity is 30 to 40% higher than that of lead.
4. Large thermal conductivity: 5 times that of mold steel; small coefficient of
5. thermal expansion: only 1/2 to 1/3 that of iron or steel, good conductivity; good weldability and processability.
Application
1. Metallurgy industry, chemical industry, machinery industry, medical ;
2. Electronics technology industry source technology industry;
3. Electric light source parts, heat shield;
4. Tungsten boat, high temperature furnace;
5. Computer, communications technology, optical materials, medicine;
6. Aerospace development, new energy materials, photosensitive material and catalyst materials.
