TUNGSTEN

Tungsten is a metal known for its exceptional heat resistance and high density.

Key Properties:

• One of tungsten’s most remarkable characteristics is its extremely high melting point of 3422°C (6191.6°F) — the highest among all metals.
• It is the heaviest naturally occurring metal, capable of maintaining its strength even at very high temperatures.
• Tungsten has a unique crystal lattice structure that makes it incredibly resilient and resistant to deformation.
• With a density of 19.26 g/cm³, tungsten is among the densest metals — approximately 2.5 times denser than steel (7.85 g/cm³).
• Its hardness is 420-450 HV, though this can vary significantly depending on deformation and processing temperature.
• In terms of electrical conductivity, tungsten ranks eighth among metals, with conductivity roughly 31% that of copper.

MOLYBDENUM

Molybdenum is a chemical element.

Key Properties:

• Symbol: Mo, Atomic Number: 42
• In its pure form, molybdenum is a silvery-gray metal with a Mohs hardness of 5.5 and a standard atomic weight of 95.95 g/mol.
• It has a melting point of 2623°C (4753°F), the sixth highest among naturally occurring elements — surpassed only by tantalum, osmium, rhenium, tungsten, and carbon.
• Molybdenum resists extreme temperatures without significant expansion or softening, making it ideal for high-heat applications such as military armor, aircraft parts, electrical contacts, industrial motors, and filament supports.
• Most high-strength steel alloys (e.g., 41xx series steels) contain 0.25–8% molybdenum.
• Due to its lower density and more stable pricing, molybdenum is sometimes used as a substitute for tungsten. It can also be used as a flame-resistant coating for other metals.
• While its melting point is high, molybdenum oxidizes rapidly above 760°C (1400°F), which is why it is more suitable for use in vacuum environments.

TZM

Used in high-heat industrial applications.

Key Properties:

• TZM (Mo 99%, Ti 0.5%, Zr 0.08%) is a corrosion-resistant molybdenum superalloy capable of withstanding molten fluoride salts at temperatures above 1300°C (2370°F).
• It offers approximately twice the strength of pure molybdenum, with improved ductility and weldability.
• Due to its excellent mechanical properties at high temperatures and pressures, TZM alloys are widely used in defense and military applications.
• Typical uses include torpedo engines, rocket nozzles, and valve bodies in gas pipelines, where components must endure extreme thermal and mechanical stress.
• TZM is also used as radiation shielding in nuclear applications.

WCu

WCu Alloy Welding Electrode

Key Properties:

• Tungsten-copper alloy (WCu) is a highly refractory metal composite widely used in metalworking and high-temperature smelting applications.
• The WCu welding electrode combines the plasticity and high conductivity of high-purity tungsten powder and high-purity copper powder, refined through processes such as static pressure casting, high-temperature sintering, and melting.
• It is capable of maintaining excellent performance, particularly in the metal smelting industry, where corrosion and wear caused by molds used for tungsten steel and high-temperature superhard alloys are common. Compared to standard electrodes, WCu alloy welding electrodes offer: High corrosion resistance, Exceptional wear and impact resistance, Dimensional stability (resistance to deformation), Good thermal conductivity, Low operational loss, High processing efficiency, Extended service life.
• WCu alloy welding electrodes are widely used as EDM (Electrical Discharge Machining) and ECM (Electrochemical Machining) electrodes, as well as resistance welding electrodes. They are extensively applied across various industries, including motor manufacturing, electrical power, electronics, metallurgy, aerospace, aviation, and other high-performance sectors.

GLIDCOP® is a family of copper-based alloy systems reinforced with ultra-fine aluminum oxide (Al₂O₃) particles. This unique combination results in high strength while maintaining excellent electrical and thermal conductivity.

Multiple GLIDCOP grades are available to meet a wide range of strength and conductivity requirements, depending on specific application needs.

One of the primary applications of GLIDCOP is in resistance welding electrodes. When properly applied, GLIDCOP electrodes consistently outperform Cu-Cr and Cu-Cr-Zr electrodes, particularly due to their exceptional resistance to high-temperature softening. GLIDCOP is widely used in the industry for resistance welding operations.

Key Properties:

• Exceptional resistance to thermal softening
• High electrical and thermal conductivity
• Excellent tensile strength
• Maintains high strength at elevated temperatures
• Superior high-temperature tensile performance
• Anti-adhesion properties during welding of coated materials
