There are three forms of vacuum coating: evaporation coating, sputtering coating, and ion plating. It is currently the mainstream technology to achieve film growth by means of physical vapor deposition (PVD). UMM produces and supplies various forms of high-quality and high-purity metal evaporation materials and sputtering targets to ensure that users get the best coating quality.

Metal Organic Chemical Vapor Deposition (MOCVD) is a chip epitaxial technology for preparing mixed semiconductor devices, metal and metal oxide and metal nitride film materials. The heating system is an important part of the MOCVD equipment. Whether it can heat the substrate quickly and uniformly directly affects the quality of film deposition, thickness consistency, and chip performance. The rhenium alloy under UMM has 10 years of professional production technology experience in the production of rhenium heaters for MOCVD and a complete quality control management system. It is a substitute for imported big-name or original parts of rhenium heaters for MOCVD and can carry out OEM full-process foundry. It is the number one domestic manufacturer with the most technical development strength and quality assurance ability.

At present and in the future, the miniaturization and multi-functionalization of electronic components put forward higher requirements for the heat dissipation of the devices. High-performance heat dissipation (thermal management) materials need to have the characteristics of low density, high thermal conductivity, and thermal expansion matching with semiconductor chip materials, good hardness, and excellent air tightness. Tungsten-copper and molybdenum-copper are often preferred as heat sink materials due to the above advantages. UMM customizes a series of high-quality tungsten copper, molybdenum copper products for users.

Ion implantation technology refers to doping boron, phosphorus and arsenic plasma on the surface of semiconductor wafers to change its electrical characteristics and device conductivity, or to use non-doped elements such as germanium and carbon to achieve the goal of modifying the surface properties of wafer materials. The ion source is the core component of the ion implanter, mainly composed of various tungsten and molybdenum components. The ion implantation industry has very stringent requirements for impurity elements. Any excess of impurity elements may cause contamination and failure of ion implantation materials. Therefore, tungsten or molybdenum materials for ion implantation must first meet their strict requirements for chemical purity .

Aiming at different materials and application conditions in additive manufacturing, UMM mainly uses international mainstream advanced technologies such as plasma suspension spheroidization, plasma rotary electrode atomization, gas atomization, etc., based on quality assurance, through technical ideas and equipment details Continuous improvement and innovation to minimize the production cost of powder consumables, and accurately customize all kinds of cost-effective elementary metals, alloys, and ceramic spherical powders for users.

The industry generally refers to materials with a Vickers hardness HV of 10~40GPa as high-hard materials, generally represented by metal-based or ceramic-based composite materials, such as cemented carbide, silicon carbide, corundum (alumina), etc.; Vickers hardness HV Those larger than 40GPa are called superhard materials, which mainly refer to diamond and cubic boron nitride. Challenging and severe working conditions require materials to meet the conditions of high hardness and wear resistance, as well as harsh requirements such as ultra-high temperature, high strength, impact resistance, high transmission, and large torque. UMM precision manufactures the following three types of materials, which are used in the preparation of special tools, pumps, valves, shafts, etc., against harsh working conditions such as heavy machinery, petrochemical, aerospace, nuclear power equipment, rail transit, ship power, and special equipment. In terms of key structural components such as transmission parts and wear parts, it has unparalleled performance advantages.

Refractory metal tungsten, rhenium, molybdenum and their alloy materials are often used to make high-temperature heat vessels (high-temperature crucibles) above 2000°C. They have high melting point, high strength and hardness, good high-temperature performance, low resistivity, small expansion coefficient, and electronic escape. Feature such as small effort. As a container for high-temperature environments, this type of crucible is widely used in the field of sapphire crystal growth, rare earth smelting, coating and other industries.

Electrodes for plasma spraying, argon arc welding, and pulse arc welding are usually made of tungsten-doped thorium or rare earth cerium. Tungsten-thorium and tungsten-cerium electrodes not only have a limited service life, but also thorium is a radioactive element. Tungsten-doped thorium is in the manufacturing and use process It is harmful to the human body and the environment. The use of tungsten rhenium electrode can effectively inhibit the growth of crystal grains caused by recrystallization during use of the electrode, improve the electron emission characteristics of the material, reduce the formation of hole defects and burnout of the electrode under the action of arc, and extend the service life of the electrode 2~ 3 times, and environmental protection without any radioactive hazards. UMM uses new tungsten rhenium electrodes to replace tungsten thorium and tungsten cerium electrodes, which greatly improves economy and efficiency.
