Typical properties of our heavy tungsten alloy products
Tungsten heavy alloys have many special properties such as high density (15.8-18.7g/cm3), high melting point, wear resistance, high tensile strength, good elongation capacity, low vapor pressure, excellent thermal stability and high radiation absorption capacity, etc.. And due to these advantages they are widely used in various fields including the sports, industry and medicine, etc.. The most common high density Tungsten alloys are W-Ni-Fe and W-Ni-Cu.
Stanford Advanced Materials supplies different kinds of high density Tungsten Alloy products and we can manufacture them according to clients' specifications.
