Answer:
Explanation:
Tungsten is a very hard and strong metal that is commonly used in the production of various types of high-strength materials, such as steel alloys, filaments for incandescent light bulbs, and electrical contacts. Tungsten has the highest tensile strength of any metal, which means it can withstand the highest amount of stress without breaking or deforming. However, tungsten is not very resistant to corrosion, especially in the presence of oxygen. At high temperatures, tungsten can react with oxygen to form tungsten oxide, which can cause corrosion of the metal.
Tantalum, on the other hand, is a highly corrosion-resistant metal that is often used in applications where exposure to oxygen and other corrosive materials is a concern. Tantalum has a natural oxide layer on its surface that helps protect the metal from corrosion. This oxide layer is very stable and adheres strongly to the underlying metal, providing an effective barrier against oxygen and other corrosive substances. Tantalum also has a relatively high tensile strength, making it a good choice for applications where both strength and corrosion resistance are important considerations.
In summary, while tungsten has the highest tensile strength of any metal, it is not as resistant to corrosion as some other metals, such as tantalum. Tantalum is highly resistant to corrosion by oxygen and other corrosive substances, making it a good choice for applications where exposure to these materials is a concern. Tantalum also has a relatively high tensile strength, making it a good choice for applications where strength is important.
