Molybdenum Copper Alloy Foil

Mo alloys have better sealing capacities, workability, and are far more lightweight than tungsten-copper alloy which makes them highly favorable for specialized plications such as aerospace.

The production of the foil starts from the powder metallurgy process where a mixture of molybdenum and copper powder is compacted then placed in a mold for sintering. It is then subjected to a series of mechanical processes such as rolling, cutting, drawing, and polishing. Machined ferrous alloys possess an elevated melting point, high conductivity for electricity and heat, low magnetism, minimal gas content, excellent high temperature stability, good heat emission, economical pricing, and a prolonged functional lifespan.

MoCu Alloy Foils are extensively utilized in military hardware, vacuum electronics, and for electromagnetic shielding. Their versatility ranges from the microelectric sector to integrated circuits, optical communications, high-temperature applications, and even in the microelectronics industry.

1. Ultra-thin form, perfect conductivity: Thickness is able to reach sub microns, possessing a melting point of molybdenum (2623°C) and conductivity of copper (IACS around 98%) along with adjustable thermal expansion coefficient, ideal for sillicon-based semi conductor materials.

2. Thermal resistance and corrosion resistance: Retains structure at 1000 degrees celcius, having strong acid and alkali corrosive resistant properties, ideal for sulfur working conditions.

3. Electromagnetic shielding, Flexibility: Shielding performance at high frequency band (10GHz) is 80dB and flexible with the ability to bent, radius of 2mm, without performance change.

Molybdenum copper alloy foil is used as a substrate for IGBT and SiC power devices to improve heat dissipation efficiency.
Molybdenum copper alloy foil serves as a conductive layer for wearable device FPC, replacing traditional copper based materials.
Molybdenum copper alloy foil is used for satellite heat sink plates without delamination during ± 100 ° C thermal cycling.
