Molybdenum Target Applications

Molybdenum target is mainly used in plasma sputtering industry. With the electric field, electron collided with the argon atom when fly to the substrate, then argon atoms and electrics were ionized .The electrics fly to the substrate while argon atoms accelerate to bomb the target, the neutral atoms (or molecules) in the target deposit on the substrate and become the coating.

Since the molybdenum resistant to high temperature and corrosion, molybdenum targets have applications in petroleum chemical industry, aviation, machine manufacturing, and electronics semiconductor industries and so on.

We  can provide molybdenum target that made with molybdenum powder which purity is 99.95%. High quality products have been made after decades of procedures such as pressing, sintering, rolling, cutting and surface grinding. Super sputtering target (single heavy reach to 120kg) is available at present..

Types of Molybdenum Alloy

Molybdenum alloy is a nonferrous alloy consisting of other elements with molybdenum as the matrix. Types of molybdenum alloy include TZM and TZC alloys, MHC and ZHM alloys, molybdenum-tungsten alloy, molybdenum-rhenium alloy, MH and KW alloys.

TZM and TZC Alloys

TZM is an acronym for titanium-zirconium-molybdenum, and is typically manufactured by powder metallurgy or arc-casting processes. It is an alloy that has a higher recrystallization temperature, higher creep strength, and higher tensile strength than pure, unalloyed molybdenum. Available in rod and plate form, it is often used for hardware in vacuum furnaces, large x-ray equipment, and in creating tools. TZC alloy is using powder metallurgy and vacuum arc melting method of preparation. It may make space rockets flying devices and surface components, etc.

MHC and ZHM Alloys

MHC alloy is a particle-reinforced molybdenum alloy which contains hafnium and carbon. The carbon is uniformly distributed along the alloys structure giving it excellent heat and creep resistant properties at elevated temperatures of 1550°C (2822°F). This alloy is able to function under extreme mechanical and thermal loads. ZHM alloy, mass percentage of each component is zirconium 0.4 to 0.7, 1.2 to 2.1 hafnium, 0.15 to 0.27 carbon. Both TZM and MHC have found application as metalworking tool materials. 

Molybdenum-tungsten Alloy

Molybdenum tungsten alloy has better corrosion resistance, making it better able to resist molten zinc. Molybdenum has a high melting point and high density, so tungsten-molybdenum alloy also has these characteristics. Molybdenum and tungsten alloy can have a different proportion of tungsten, such as 30% tungsten or 50% of tungsten.

Molybdenum-rhenium Alloy

Molybdenum-rhenium is a highly pure alloy containing only two elements (molybdenum and rhenium), and serves a wide range of applications in electronics, furnace, joining, and aerospace industries. Precise alloying of the refractory metals rhenium and molybdenum adds both ductility and strength to suit different specifications. It is a superconductive alloy with a noble surface chemistry and a relatively high transition temperature.

MH and KW Alloy

MH alloy adds potassium and sulfur elements with molybdenum as the matrix; KW alloy is a molybdenum alloy with potassium, silicon and other elements added in the molybdenum matrix.

Molybdenum Copper Alloy Properties

Molybdenum copper is alloy of molybdenum and copper. It is a great alternative to tungsten copper for weight sensitive applications, with many good properties.

1. High electrical and thermal conductivity. Molybdenum is a better element for electricity conductivity except for gold, silver and copper in the metals. Therefore, molybdenum copper alloy composed by molybdenum and copper have very high electrical and thermal conductivity.

2. Adjustable low coefficient of thermal expansion. The coefficient of thermal expansion of copper is higher, but the coefficient of thermal expansion of molybdenum is very low. Therefore, the low coefficient of thermal expansion can be made by different proportion of the components according to the requirements, in order to make them appropriate and combine with other materials, avoid the damage of thermal stress caused by large differences in coefficient thermal expansions.

3. Special high temperature property. The melting point of molybdenum is 2 610, and the melting point of copper is only 1083, molybdenum-copper alloy have good strength property and definite plasticity in ordinary temperature. And if the temperature exceeds the melting point of copper, the copper will change to liquid and evaporate to absorb heat, to make cooling effect. This performance can be used as special-purpose high-temperature materials, such as the nozzle throat which can be resist combustion temperature of gunpowder, electrical contact which under high-temperature electric arc, and so on.

4. Molybdenum copper alloy is non-magnetic. Both molybdenum and copper are non-magnetic non-ferrous metals. Hence the composition of Mo-Cu alloy is an excellent non-magnetic material.

5. Molybdenum copper alloy has low gas content and a good vacuum performance. Either molybdenum or copper, its oxides easy to restore, their N, H, C and other impurities can easily be removed, thereby maintaining low outgassing and makes full use of performance of the vacuum.

6. Molybdenum copper alloy has good machinability. Because of high hardness and brittleness, it is difficult to machine the pure molybdenum. Mo-Cu alloy, because of copper's incorporation, the hardness reduced and plasticity increases, so it is beneficial to machining, and can be processed into complex shapes components.
