Products Description
Molybdenum copper alloy is a composite material consists of molybdenum and copper, which is easier to machine and mass produce in comparison to tungsten copper.
As a product of molybdenum copper alloy, Molybdenum Copper Foil is very suitable for contact materials. With respect to mechanical properties, molybdenum copper alloys possess high melting point, high thermal conductivity and electrical conductivity, low expansion coefficient of thermal, great resistance to thermal shock, high temperature performance of good, heat resistance and ideal vacuum performance.
Molybdenum Copper Foils have such importance that they are used in integrated circuits, military defense, and high power smelting, Vacuum, Optical communications, micro electronics and space. Furthermore, Molybdenum Copper Foil can work as an electromagnetic shielding material for high voltage power equipment and medical radiation equipment because of the non magnetic nature of molybdenum and copper.
Features of Molybdenum Copper Foil
Micrometer dimensions achieved by ultra-thin highly precise slicing methods such as rolling or chemical deposition, which provide unmatched surface flatness exceeding 0.1μm.
Minimal cooling threshold window aligns with high thermoelectric performance: Achieving thermal expansion coefficients of 6.5×10⁻⁶/K enables tailoring of chip ceramic composite substrates to mitigate stress.
Electromagnetic shielding capability. Molybdenum Copper Foil offers exceptional shielding capability reaching 80dB for high-frequency circuit interference around 10GHz.
Applications of Molybdenum Copper Foil
Molybdenum copper foil acts as a substrate for power devices like IGBT and SiC MOSFETs, offering high power density heat dissipation.
Molybdenum copper foil is applied in flexible circuit boards (FPCs) of wearable devices, supporting fracture-free stable conductivity under bending radius ≤ 2 mm.
Molybdenum copper foil is the layer of electromagnetic shielding applied to the 5G base station antenna feeding network for signal crosstalk suppression.
