Product Description
Because tungsten has the highest melting point of all metals (6180°F/3420°C), casting Tungsten Alloy components or parts is not possible.
So ASTM B777-15 Tungsten Alloys Parts, Plate, Shapes, Sheets And Other Forms Available In Various Densities And Grades are produced by powder metallurgy techniques which provides customers many cost saving benefits. For example single pieces, small batch quantity parts, components or shapes can be produced at near-net sizes minimizing the machining required and reducing the waste material lost during the machining process. It usually is more economical and efficient to produce a series of smaller parts instead of one large part that can then be assembled into a larger unit by press fitting, mechanical fastening, brazing, etc. For complex parts or where close tolerances must be met, a
blank is often produced to near-net size either in the die design stage or by cutting the blank during the pre-sintered state, minimizing machining
nd material costs.
Characteristics and features
As medical science developing, there is more and more radiation in our life, which has become a new trouble, such as X-ray radiation, gamma radiation (energetic electromagnetic radiation), radiation of alpha particles (helium atoms) beta particles (electrons) and cosmic radiation, etc. In order to protect patients and other people safe from harmful effects of ionizing radiation, such as breast cancer, skin cancer, etc. One type of excellent radiation-absorbing medium is badly needed. Experts find that radiation exposure could be reduced by maxing shielding. The density of a material is related to its radiation stopping ability. Higher density means better stopping power and shielding. With a higher density, tungsten alloy has a greater protection than lead. It is greater linear attenuation of gamma radiations means that less is required for equal shielding. Alternatively equal amounts of tungsten alloy shielding provide diminished exposure risks than equivalent lead shielding.
