Frequently Asked Questions (FAQs)
- What is Tungsten and what is its application?
A hard, brittle, corrosion-resistant, gray to white metallic element extracted from wolframite, scheelite, and other minerals, having the highest melting point and lowest vapor pressure of any metal.
Tungsten and its alloys are widely used in High-temperature environments because its high melting point, meanwhile its composites are used in High voltage environments as contacts and electrodes.
Tungsten parts are also used as weights since its high density.
Tungsten is an idea material that can replace lead in radiation protection fields. - Are all tungsten alloys inherently brittle?
No. Experiences with pure tungsten in the recrystallized state may cause the misunderstanding. Tungsten heavy alloy has a totally different, rounded grain structure that provides good machining behavior.
- Is tungsten heavy alloy similar to tungsten carbide?
While both families of materials are made by the powder metallurgy process of liquid phase sintering and are both very rigid, many differences exist. Tungsten carbide provides high hardness and wear resistance, whereas tungsten heavy alloy gives both ductility and higher density.
- Why is tungsten so much more expensive than lead?
The significantly higher cost of tungsten results from the higher cost of the mined ore as well as the more complicated processing steps needed to get to the metallic state. While costing more, tungsten provides a number of benefits over lead - including both material performance and environmental factors.
