1. Definition and composition of molybdenum alloy Molybdenum alloy, as the name implies, is an alloy material composed of molybdenum as the main component and other elements added. Molybdenum (Mo) is a silvery-white metal element with high melting point, high hardness, and good thermal and electrical conductivity. In molybdenum alloys, the content of molybdenum is usually high, a key factor determining its performance. Beyond molybdenum, the alloy may include elements like iron, nickel, cobalt, chromium, and even copper in specific formulations—such as molybdenum copper or molybdenum copper alloy, which combine molybdenum’s high-temperature resistance with copper’s conductivity. The addition of these elements, including copper in copper moly composites, enhances properties like strength, corrosion resistance, and wear resistance. 2. The proportion of molybdenum in molybdenum alloys applications, molybdenum content ranges widely based on performance needs and use environments. For example, high-strength molybdenum alloys may contain over 90% molybdenum, while alloys requiring high corrosion resistance might adjust molybdenum proportion by adding other elements—including copper in moly copper alloys to balance conductivity and heat dissipation. In copper moly copper structures, the layered composition further tailors properties for specific uses, such as electronic packaging. 3. Properties of molybdenum alloys Molybdenum alloys offer excellent properties from their unique component mix. High molybdenum content grants a high melting point and hardness, ideal for high-temperature environments. Adding elements like copper in molybdenum copper alloy adjusts strength, ductility, and corrosion resistance for diverse applications. For instance, molybdenum copper composites combine molybdenum’s thermal stability with copper’s high thermal conductivity, making them suitable for heat sinks in electronics. Additionally, these alloys maintain good electrical conductivity, critical for applications requiring efficient energy transfer. 4. Preparation process of molybdenum alloys The preparation of molybdenum alloys—including molybdenum copper and copper moly variants—typically involves batching, smelting, pouring, heat treatment, and machining. For molybdenum copper alloy, raw materials like molybdenum powder and copper are accurately weighed, then sintered or infiltrated to form a composite. High-temperature smelting ensures uniform mixing, while heat treatment optimizes the microstructure. Machining converts the alloy into products like moly copper heat spreaders or electrical contacts, with China-based manufacturers often specializing in such precision processes. 5. Application fields of molybdenum alloys Molybdenum alloys, including molybdenum copper and copper moly materials, have wide-ranging uses: Price and market considerations Molybdenum alloy price fluctuates with raw material costs (e.g., molybdenum and copper prices), alloy composition (e.g., high-molybdenum vs. molybdenum copper), and processing complexity. China molybdenum alloy suppliers often offer competitive pricing for standard and custom moly copper or copper moly products, making them preferred choices for industries seeking a balance of performance and cost. Molybdenum alloys—from pure molybdenum-based materials to molybdenum copper alloy composites—deliver versatile performance

Basic knowledge of titanium metal The element titanium (Titanium) was first discovered by British scientist Gregor in ilmenite in 1791. Later, German chemist Klaprus also discovered it from rutile in 1795 and named it “titanium”. However, due to the extremely high chemical activity of titanium, the refining process is quite difficult. It was not until 1910 that American scientist Hunter successfully extracted pure titanium for the first time through sodium reduction. In 1940, Luxembourg scientist Kroll further adopted the magnesium reduction method and successfully produced sponge titanium, thus laying a solid foundation for the large-scale industrial production of titanium. It is worth mentioning that the reserves of titanium in the earth’s crust are considerable. It ranks fourth, second only to iron, aluminum, and magnesium, and its reserves far exceed the sum of commonly used metals copper, nickel, lead, and zinc. In industry, ores such as rutile, white titanium ore, perovskite, and ilmenite are widely used to produce titanium. In addition, titanium metal also has many excellent properties. From the appearance, it is silver-gray, similar to steel, but its performance is better than ordinary metals. ① Titanium metal has low density and high strength, which is very suitable for the needs of lightweight construction. Its density is 4.54g/cm3, which is only 56% of ordinary structural steel, but its strength is equivalent or higher. Among metal structural materials, titanium’s specific strength (that is, the ratio of material strength to density) ranks among the best. In addition, adding a small amount of titanium to the alloy can significantly improve its performance. ② Titanium can react quickly with oxygen in the natural environment to form a strong oxide film, which gives it excellent corrosion resistance. This oxide film can remain stable in oxidizing acids, alkalis, and salt media, especially in wet chlorine and seawater, where its corrosion resistance is even better. Therefore, titanium is very suitable for harsh environments such as seaside, acid rain and volcanic areas. ③ Titanium’s expansion coefficient is about half that of stainless steel and copper, which makes it less stress when the temperature changes. Therefore, it is very suitable for use in environments with large temperature changes, such as the roof of a building. ④Titanium is a non-combustible material with a melting point of up to 1660℃ and can withstand a high temperature of 1100℃ in a fire. In addition, titanium alloys also have excellent thermal strength, which is far superior

Application of tungsten-copper composite materials in EDM and welding processing Tungsten, a metal element, is theoretically considered an ideal electrode material. Its excellent strength, density and high hardness characteristics, coupled with a melting point close to 3400°C, make the tungsten electrode extremely low in practical applications. For this reason, tungsten-copper composite materials play a vital role in the field of EDM and welding. However, although pure tungsten has many advantages in theory, it faces two major problems when used as an electrode: one is that it is extremely difficult to process, and the other is that it is relatively expensive. In order to overcome these challenges, scientists have cleverly combined the excellent properties of pure copper, such as plasticity and high conductivity, to develop tungsten-copper composite materials. This material not only retains the high strength, high density and high hardness of tungsten, but also incorporates the processing advantages of copper, making it an ideal electrode choice in the field of EDM and welding.
