| I. Composition of Platinum-Tungsten Alloy |
Platinum-tungsten alloy is made by mixing platinum and tungsten in certain proportions. Typically, the composition of the alloy is 75% tungsten and 25% platinum, although there are other ratios available. The preparation of platinum-tungsten alloy requires high temperature and high pressure conditions and can be achieved through melting or physical-chemical methods. |
| II. Properties of Platinum-Tungsten Alloy |
Platinum-tungsten alloy is a special alloy material with high density, high strength, high hardness, and high melting point. Its density is up to 18.6g/cm³, which is more than double the density of either platinum or tungsten alone; the melting point is 3420ºC, over 1.5 times that of pure platinum; it has high strength with strong resistance to bending, tensile, and compressive forces; and it is hard, exhibiting wear and corrosion resistance. |
| III. Applications of Platinum-Tungsten Alloy |
Due to its unique physical and chemical properties, platinum-tungsten alloy is widely used across various industries. The main application areas include: 1. Jewelry: The lustrous color and high density of platinum-tungsten alloy make it one of the materials used for high-end jewelry. 2. Electronics: The high melting point, high strength, and high density of platinum-tungsten alloy make it the preferred material for manufacturing high-temperature gap materials and cathode materials in the electronics industry. 3. Aviation: With its excellent properties of high temperature, high pressure, high strength, high hardness, and high toughness, platinum-tungsten alloy is widely used in the manufacturing of high-temperature high-strength components in the aviation and aerospace fields. |
1, Introduction to Platinum Tungsten Wire Composition
Platinum tungsten wire is a widely used high-temperature wire, composed of two metals, platinum and tungsten, with high temperature corrosion resistance and good mechanical properties. Platinum tungsten wire is widely used in the manufacturing of high-pressure sodium lamps, halogen lamps, xenon lamps, and solar cells in high-temperature environments due to its unique physical properties.
2, Composition ratio and influencing factors of platinum tungsten wire
The ratio of platinum to tungsten in platinum tungsten wire directly affects the properties and properties of the wire. Generally, the ratio of platinum to tungsten is 1:1 or 2:1. When manufacturing platinum tungsten wires, electrochemical deposition vacuum heat treatment is generally used. By precisely controlling temperature and vacuum degree, high-quality platinum tungsten wires can be obtained.
At the same time, the composition of platinum tungsten wire is also affected by other factors, such as the temperature of the usage environment, atmosphere, particles, etc., which can also lead to changes in the performance of platinum tungsten wire.
