Tungsten alloy is an alloy composed of tungsten and other elements. Among metals, Tungsten and Alloys have the highest melting point, good high-temperature strength and creep resistance, as well as thermal conductivity, electrical conductivity, and electron emission performance. In addition to being widely used in electronics, aerospace, weapons and other fields, Pure Tungsten is also used to manufacture tungsten alloy. In this article, we will take a look at the 3 most common types of tungsten alloys.

 

Molybdenum-tungsten alloys are molybdenum-based alloys containing 25% and 30% tungsten and have excellent properties to prevent corrosion of molten zinc.

Tungsten Heavy Alloy can be used at higher temperatures than molybdenum or molybdenum alloys. For example, when the molybdenum-tungsten alloy is used as the electrode, spout and thimble component in the furnace for producing high melting point refractory ceramic fiber, its service life is much longer than that of pure metal molybdenum products.

Molybdenum-tungsten alloy has higher corrosion resistance to zinc liquid than pure metal molybdenum, and it is mostly used for zinc liquid temperature measuring tube, zinc liquid pump rotor and some corrosion-resistant parts of the zinc smelting furnace.

 

Tungsten Alloy is a niobium alloy formed by adding a certain amount of tungsten and other elements based on niobium. Tungsten and niobium form an infinite solid solution.

Niobium-tungsten alloy has good high-temperature strength and good room temperature plasticity and can be made into various processed materials and parts by conventional forming processing technology. It is mainly used for space shuttle skin, nuclear reactor engineering, jet engine parts, and heat radiation screens and ducts for space power generation systems.

 

Tungsten Carbide is the most common and most important form of tungsten alloy. Unlike the previous tungsten alloys, its main components are tungsten, carbon, and cobalt, so it is also often called tungsten-cobalt alloy.

Tungsten carbide has high hardness, strength, wear-resistance and corrosion resistance, and is known as “industrial teeth”. It is used to manufacture cutting tools, knives, cobalt tools, and wear-resistant parts.

 

Pure Molybdenum is a silvery, shiny metal that belongs to Group 6A, the second transition series of the Periodic Table. It has the 6th highest melting point and is the 54th most abundant element in the world. The highest molybdenum reserves of molybdenum ore can be found in the U.S, Canada, China, Peru and Chile.

Because of its properties, it serves as a good thermal conductor and as an important alloying element in the production of structural and stainless steel. It has a high ability to resist corrosion and to hold shape even when subjected to high temperatures.

The most common among the Molybdenum and Alloys is the titanium-zirconium-molybdenum alloy (TZM), which is a blend of 0.5% titanium and 0.08% of zirconium, and about 90% molybdenum. This alloy exhibits strength even at very high temperatures, making it the perfect alloy for casting zinc.
