Molybdenum copper is a composite material of molybdenum and copper. Its performance is similar to that of tungsten copper, and it also has a thermal expansion coefficient and thermal conductivity 

that can be adjusted by adjusting the composition. However, the density of molybdenum copper is much smaller than that of tungsten copper, making it more suitable for aerospace and other fields.

Molybdenum copper is one of the important materials indispensable for the development of modern science and technology. It has the characteristics of molybdenum and copper and has good comprehensive performance.

Features of our molybdenum copper products:

☆ No sintering activation elements such as Fe and Co are added to maintain high thermal conductivity

☆ Excellent air tightness

☆ Lower density, more suitable for flight electronic equipment

☆Can reduce thermal expansion coefficient

☆Special high-temperature performance

☆High electrical conductivity and thermal conductivity


☆Low gas content and good vacuum performance

☆Good machinability

☆ When the molybdenum content does not exceed 75%, rolled plates can be provided to facilitate stamping parts

Provide semi-finished products or finished products with Ni/Au plated surface

☆Full-process technical services before, during, and after-sales

Applications of molybdenum copper composites

Due to the above properties, molybdenum-copper composite materials have broad application prospects. mainly include:

-Used as vacuum contact

-Used as a conductive heat dissipation element to meet the requirements of high electrical conductivity, thermal conductivity, heat resistance, vacuum performance, and constant thermal expansion coefficient of high-power integrated circuits and microwave devices;

-Used as some instrument components with special requirements, such as non-magnetic properties, constant thermal expansion coefficient, high elastic modulus, high electrical thermal conductivity, etc.;

-High-temperature components for rockets and missiles with lower temperatures

-Used as solid dynamic seals, reinforcing ribs for sliding friction, water-cooled electrode tips for high-temperature furnaces, electrodes for electrical machining, etc.

-Wireless communication, metal carrier board for wireless communication: tungsten-copper-molybdenum-copper carrier board is organically combined with ceramics to greatly improve high-frequency transmission performance

-Optical communication: used in server LSI components, used in communication base stations, etc.

-Semiconductor lasers: LC and LED components

-Power module: low loss and efficient heat dissipation, can be used in high power density modules
