Platinum-ruthenium Alloys
Platinum-ruthenium alloys have a unique combination of physical and mechanical properties. These alloys are used in jewelry, electronics, medicine, automotive, industrial and aerospace components. Platinum-ruthenium alloys offer good electrical, thermal and corrosion-resistant properties as well as excellent durability. The good wear resistance also makes this alloy suitable for applications in many industries, such as aerospace and automotive industries.
Platinum-ruthenium alloys are composed of platinum and ruthenium in different proportions. Usually, the ratio range from 5-10% ruthenium to 90-95% platinum. Some exceptions are such alloys with higher ruthenium content, up to 45%. The physical properties of platinum-ruthenium alloys are dependent on the ratio of the two components.
Platinum-ruthenium alloys have high electrical and thermal conductivity which makes them well-suited for high-speed electronics and heating elements. These alloys also have low electrical resistivity and high radiation resistance. They are also very corrosion resistant, meaning they can resist exposure to strong acids, alkalies, and salt water. This corrosion resistance makes them ideal for applications such as fuel cells, ship hulls, and chemical piping.
Platinum-ruthenium alloys are also resistant to wear. This makes them suitable for applications such as bearings, valves, and tiny precision parts.
Due to its versatility, platinum-ruthenium alloys are used in a variety of applications. These alloys are used in the automotive and aerospace industries for engine parts, tools, and fasteners. The alloys are also used in the electronics industry for components such as semiconductors, contacts, and resistors. They are also used in the medical field for implants and surgical instruments.
The melting point of platinum-ruthenium alloys is lower than pure platinum, which allows for easier fabrication. The alloys are also easier to machine and shape than pure platinum. Furthermore, platinum-ruthenium alloys are easier to weld than pure platinum. This makes them suitable for many applications that require joining two or more pieces of metal.
In conclusion, platinum-ruthenium alloys have many advantages. They are corrosion-resistant, have high electrical and thermal conductivity, have low electrical resistivity, and are resistant to wear. They are also easy to shape, machine, and weld. These properties make platinum-ruthenium alloys suitable for a variety of applications in industries such as automotive, aerospace, electronics, medicine, and industrial components.
