Cu/Mo/Cu Heat Sink Price on July 26, 2022

0.4x3.715x1.5mm Cu/Mo/Cu heat sink price is 1.10USD/PC on July 26, 2022. They are mainly used in radio frequency, microwave and semiconductor high-power devices, heat sinks, lead frames, low-expansion layers and heat conduction channels of multilayer printed circuit boards (PCBs).

Cu/Mo/Cu heat sink (CMC) is a composite material with a similar sandwich structure, the core material is molybdenum, and both sides are covered with copper. The basic concept of the design is to use the high thermal conductivity of copper and the low thermal expansion characteristics of molybdenum. By adjusting the thickness ratio of copper, molybdenum and copper, it can achieve a thermal expansion coefficient matching ceramic materials and semiconductor materials, and a higher thermal conductivity. The expansion coefficient and thermal conductivity are designable.

The ideal heat sink material should have a linear expansion coefficient CTE, which is basically matched with the chip, and has the highest possible thermal conductivity, especially the Z-direction (thickness) thermal conductivity, so that the heat of the packaged chip and other electronic devices can be quickly discharged. In order to increase its power density, achieve high power, reduce the volume and realize the miniaturization of the device. CMC material is now the one of the materials to meet above requirements.

Duplex Stainless Steel Containing Molybdenum Is Used in Xiamen Mountains-to-Sea Trail

Carbon steel is widely used around the globe for the construction of bridges of sizes ranging from the very large to the very small, but now many bridges around the world are approaching the end of their useful life because carbon steel bridges do not have the corrosion resistance benefits offered by chromium, molybdenum and other alloying elements. 

The forward-looking design of the Soderstrom Bridge with duplex stainless steel highlights the benefits of building bridges from structural stainless steel in coastal areas or where deicing salts are used. Molybdenum-containing stainless steels will play an ever-increasing role in much-needed infrastructure upgrades and new builds around the world for the benefit of the environment and the people who depend on them.

Duplex stainless steel bridge structures were praised for their attractive appearance when they were first introduced, with novel designs emerging such as Singapore's Double Helix Bridge and the world's longest mono-cable suspension bridge with a curved deck in Xiamen, China. Nowadays, designers are increasingly looking at the properties of the material beyond its aesthetics. In many applications, even in concealed applications, its strength and corrosion resistance are used to create structures that are lighter than carbon steel in the past. The materials used and less maintenance is required.

All duplex grades are at least twice as strong as 316 stainless steel and have good weldability for a wide range of applications. This material of bridge structures is gaining popularity around the world due to their longer service life and lower maintenance requirements.

While all steel is 100% recyclable, options with stainless steel have a lower environmental footprint. If the stainless steel is selected correctly, the bridge structure will not fail over time. Stainless steel can achieve a near-infinite life expectancy when properly maintained to specification requirements. It also does not require any environmentally harmful surface treatment to resist corrosion

The Soderstrom Bridge was built with 2404 duplex stainless steel, the first bridge to be designed with this grade of stainless steel. This stainless steel contains 1.6% molybdenum, which contributes significantly to its crevice corrosion and pitting resistance. In fact, this type of stainless steel not only has twice the yield strength of 316 stainless steel, but also has improved atmospheric corrosion resistance.

Xiamen Mountains-to-Sea Trail (Health Footpaths) starts at Dongdu Cruise Plaza and ends at Guanyin Mountain Beach. It includes an 11km elevated trail and seven long-span node bridges, as well as newly remodeled green spaces along the walkways. The project also connects eight mountain ranges, namely Huwei Mountain, Xianyue Mountain, Yuanshan Mountain, Xueling Mountain, Hutou Mountain, Jinshan Mountain, Huzi Mountain and Guanyin Mountain, as well as 3 waters of Yundang Lake, Wuyuanwan and Hubin Reservoir. The idea of the walkway is to connect these oasis of harmony and tranquility with bridges, creating a continuous path independent of the busy life of the city below.

The construction time of Xiamen health footpaths was short, and the hills and forests in the environment were extremely challenging. Therefore, designers chose to use highly prefabricated components. Due to their low weight, these components could be transported to the site without heavy machinery, with minimal damage to vegetation.

Stainless steel containing molybdenum is used through the all footpath. For example, Hemei Bridge, one of seven footbridges that are part of the Xiamen Mountains to Sea Trail, a 23-kilometre large-scale network of footpaths, elevated walkways, and footbridges, the suspension system consists of a three-part main cable (fully locked steel cables) and 36 hanger cables (stainless steel spiral strands). The main cable joins the tips of the V-shaped mast and connects the mast to the abutments. The eccentrically arranged hanger cables connect the curved deck to the main cable. The V-shaped mast is situated along the central symmetry axis, stabilized by four guy cables.

In terms of physical and chemical properties, the color of moly wire is silver gray or black (surface covered with graphite), with higher melting point, higher density, higher tensile strength, lower resistivity, and lower thermal expansion, coefficient, small elongation, good high temperature resistance and acid and alkali resistance. It should be noted that when heated in air, it will react with oxygen; the overall performance of doped wires is generally better than that of pure wires

From the production process point of view, pure wire is a kind of product that uses hot and cold drawing combined process to process high temperature molybdenum raw material into filament. The production method of doped wire is a solid-liquid doping method, that is, adding an appropriate amount of solid solution metal elements and rare earth oxides to solid molybdenum dioxide, then mixing evenly, and finally performing hydrogen reduction and isostatic pressing. , sintering, hammer tandem, hot wire drawing, annealing and cold wire drawing.

In terms of usages, moly wire is generally used for winding core wire, bracket, lead wire, electronic tube reed, grid, heating element, molybdenum foil belt, wire cutting high temperature components, auto parts spraying, etc.

In terms of storage methods, molybdenum wire is generally placed in a ventilated and cool place with low humidity and temperature to avoid oxidation. In addition, the problem of poor verticality may occur when it is left for more than 6 months.

What Do You Know About the Applications of Molybdenum Foil?

What is molybdenum foil? 

Normally, a plate with thickness less than 0.1mm will be called foil. It is lightweight and flexible, and is produced by powder metallurgy with purity more than 99.95%. Chinatungsten Online has sophisticated production equipment, which can produce moly foil according to the thickness, surface condition and tolerance required by customers. 

Mo foil applications 

Molybdenum can withstand extremely high temperatures without significantly changing, expanding or softening. This ability makes its engagement in high temperature situations very useful. Therefore, molybdenum metal can be used in the manufacture of armor, aircraft parts, industrial motors, filaments and electrical contacts.

Originally, molybdenum is primarily used as an alloying agent in steel. However, in 1906, William D. Coolidge applied for a patent to make molybdenum ductile, thereby being used as heating elements (molybdenum rods) and shields (molybdenum sheets) in high-temperature furnaces. Molybdenum sheets are also used in the manufacture of missiles and aircraft parts and in the nuclear power industry.

With the advance of technology, thinner sheets are available that is foil. Molybdenum foil is often used for heat and x-ray shielding, production of drawn parts, electronic components, metalizing sources, furnace insulation, and chemically etched parts, and has the ability to be etched into fine patterns, making it useful in the semiconductor industry.

In addition, Mo foils are desirable for space applications. They may be used as a substrate for the fabrication of CdS-CdTe solar cells. Interaction of selenium, arsenic hydrides, stibine and bismuthine with Mo foil was investigated by atomic absorption spectroscopy. Furthermore, they may be used to generate metal diffusion bonding in silicon carbide/silicon carbide (SiC/SiC) joints.

Mo foil packaging 

Considering the thin thickness of the foil, it has to be carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
