Product Description:Molybdenum alloys are a class of metallic materials composed of molybdenum and other elements. They have excellent physical and chemical properties, such as high melting point (up to 2620°C), boiling point (up to 5560°C), electron configuration of [Kr] 4d5 5s1, thermal conductivity of 138 W/(m·K) and hardness of 6.5. Moreover, molybdenum alloys are corrosion resistant, wear resistant and have high strength at elevated temperatures, making them a perfect choice for many industrial applications. Molybdenum alloy components are widely used in aerospace and nuclear industries, as well as in medical instruments, automobile manufacturing, petrochemical, electrical and electronic industries.
These alloys have good ductility and formability, which enable them to be used in a variety of shapes and sizes. Moreover, molybdenum alloys have excellent resistance to oxidation and high-temperature corrosion, providing superior performance and durability in extreme conditions. With their superior thermal, electrical and mechanical properties, molybdenum alloys are an ideal choice for a range of applications.
Molybdenum alloys have many advantages over other metals, such as higher melting points, higher strength, improved corrosion resistance and better electrical and thermal conductivity. They have become an essential part of many industries, offering exceptional performance and reliability in a wide range of products, from aerospace components to medical instruments.
Molybdenum Draft Tube
Also known as the molybdenum heat preservation barrel, the molybdenum draft tube is placed inside the graphite carbon felt in the single crystal furnace. The actual test results show that the argon gas in the upper part of the single crystal furnace body becomes smooth, the flow of argon gas is accelerated, and the deposition of silicon oxide in the single crystal furnace is greatly reduced. Because of the temperature protection of the molybdenum draft tube, the heating time is reduced, the crystallization time is shortened by nearly 40%, and the occurrence of crystal dislocations is also reduced. Therefore, the application of molybdenum draft tubes reduces energy consumption and improves production efficiency.
The molybdenum draft tube includes plate draft tubes and concave-convex plate molybdenum draft tubes. The concave and convex molybdenum draft tube has a brighter surface, uses less material, and reduces diffuse reflection.
The shape of the molybdenum draft tube is a horn with a big upper mouth and a small lower mouth. Because each manufacturer uses a different furnace type, the current popular molybdenum draft tubes include 20-inch, 22-inch, 24-inch, 26-inch, and 28-inch. Generally 0.5-2.0mm high-temperature molybdenum plates are used for the production and processing of molybdenum draft tubes, which are entirely cut into fan shape according to the drawing size, then heated and rolled into the horn shape for riveting or welding, and finally corrected. Finished molybdenum draft tubes’ surface finish can reach Ra0.8-1.6, and the size is so precise that it can ensure the draft tube can closely match with the graphite carbon felt.

Molybdenum alloys are packaged and shipped in secure containers, such as plastic bins, cardboard boxes, or wooden crates. The packaging should provide protection from physical damage, moisture, and other environmental factors that could damage the alloys. The containers should be labeled with the product name and an identifying marking, such as a barcode, to ensure that the correct product is being shipped.
When shipping molybdenum alloys, the containers should be securely sealed and the shipping method should be selected appropriately for the product and its destination. The shippers should also take into account the transit time and the handling of the containers during transit. The containers should be carefully inspected and checked for any damage before they are accepted for shipment.
