Molybdenum Chemical Etching – Molybdenum Etching

Molybdenum chemical etching is a specialized process used in various industries to pattern, cut, or shape molybdenum components. This method employs chemical solutions to remove material in a controlled manner, allowing for the production of intricate designs and precise geometries that would be challenging to achieve through mechanical means. Molybdenum, a refractory metal with unique properties, is widely utilized in electronics, aerospace, and other high-tech applications due to its high melting point, strength, and resistance to corrosion.

Molybdenum Chemical Etching

Molybdenum (Mo) is a transition metal with atomic number 42 and an atomic weight of 95.95. Known for its robustness and high melting point (2,623°C or 4,753°F), molybdenum finds extensive use in situations demanding high thermal and structural stability. Its applications span from electrical contacts and semiconductors to aerospace components and industrial machinery. The complexity of machining molybdenum due to its hardness and brittleness has led to the adoption of chemical etching as a viable manufacturing technique.

BE-CU ETCH offers precision etching with multiple molybdenum alloys.

How To Etch Molybdenum

Metal Grades For Molybdenum Etching

Molybdenum’s unique properties, including its high melting point, excellent thermal conductivity, and resistance to corrosion, make it an ideal material for a wide range of applications. The selection of the appropriate grade of molybdenum is crucial for the success of chemical etching processes. Different grades of molybdenum offer varying characteristics in terms of purity, alloy composition, and mechanical properties, which can influence the etching outcomes.


Pure Molybdenum

Pure molybdenum is typically used in applications requiring high thermal and electrical conductivity. It offers excellent performance in high-temperature environments and has good resistance to corrosion by most acids and bases. The purity of molybdenum used for etching typically exceeds 99.95%, ensuring minimal impurities that could affect the etching process and the final product quality.
Electronics: Thin-film transistors (TFTs), electrodes, and interconnects.
Aerospace: High-temperature components such as rocket nozzles and heat shields.
Medical Devices: Implants and surgical instruments requiring high biocompatibility.

Molybdenum-Lanthanum (Mo-La)

Molybdenum-Lanthanum (Mo-La) alloy, also known as ML, is doped with small amounts of lanthanum oxide (La₂O₃). This alloy offers enhanced ductility and creep resistance at high temperatures compared to pure molybdenum. The addition of lanthanum oxide helps to refine the grain structure, improving the material’s mechanical properties and making it more suitable for applications involving mechanical stress and thermal cycling.
Industrial Machinery: High-stress components such as molds and dies.
Aerospace: Turbine blades and other high-temperature applications where improved ductility and creep resistance are beneficial.
Lighting: Filaments and support structures in high-intensity lighting applications

Molybdenum-Rhenium (Mo-Re)

Molybdenum-Rhenium (Mo-Re) alloys contain varying amounts of rhenium (typically 5% to 47%). The addition of rhenium significantly enhances the ductility and tensile strength of molybdenum, even at low temperatures. Mo-Re alloys also exhibit improved weldability and resistance to radiation damage.
Aerospace: High-stress, high-temperature components such as turbine blades and space vehicle parts.
Medical: X-ray tubes and other diagnostic equipment.
Electronics: Advanced semiconductor devices and electrical contacts requiring superior performance and longevity.

TZM (Titanium-Zirconium-Molybdenum) Alloy

TZM is an alloy of molybdenum with small amounts of titanium (0.50%), zirconium (0.08%), and carbon (0.02%). This alloy is known for its high strength, hardness, and resistance to thermal shock. TZM also offers excellent creep resistance and maintains its mechanical properties at high temperatures.
Aerospace: Critical components in jet engines and gas turbines.
Industrial: High-temperature furnace parts and hot working dies.
Defense: Armor-piercing projectiles and missile components due to its strength and durability.

Molybdenum-Tungsten (Mo-W)

Molybdenum-Tungsten (Mo-W) alloys combine the properties of both molybdenum and tungsten, offering superior strength and thermal stability at extremely high temperatures. The tungsten content in these alloys can vary, typically ranging from 30% to 50%, depending on the desired properties. Mo-W alloys exhibit better resistance to corrosion and erosion compared to pure molybdenum.
Aerospace: Components exposed to extreme temperatures and aggressive environments, such as re-entry shields and rocket propulsion systems.
Electronics: High-performance electrical contacts and semiconductors.
Nuclear: Shielding and structural components in nuclear reactors due to their high melting point and radiation resistance.

Components That Are Produced By Etching Molybdenum

The popularity of molybdenum makes it a desirable metal for use in fabrication because it is easy to manufacture and has favorable properties for many industrial products.With the photo etching process, the metal is etched evenly without any structural deformations from the hard tooling used in stamping and punching.Since there isn’t a heat point of contact like laser cutting, the parts’ metal properties remain unchanged and free from thermal deformations.Get inspired by our custom etching part projects and contact us to Get Instant Quote for rapid prototype or molybdenum etching parts start from 1pcs.
