High-melting metals - Import export

Aluminum nitride ceramics have excellent electrical and thermal properties, and are considered to be the most promising high thermal conductivity ceramic substrate materials. In order to seal the package structure, mount components and connect input and output terminals, the surface and interior of the aluminum nitride ceramic substrate need to be metallized. The reliability and performance of ceramic surface metallization have an important impact on the application of ceramic substrates, and firm bonding strength and excellent air tightness are the most basic requirements. Considering the heat dissipation of the substrate, it is also required to have high thermal conductivity at the interface between the metal and the ceramic. The metallization methods on the surface of aluminum nitride ceramics include: thin film method, thick film method, high melting point metallization method, electroless plating method, direct copper cladding method (DBC), etc.

Ming Xiao Mfg has a friend factory produce cold forging standard fasteners,the main production is welding nuts and welding screws, Specs from M4 - M18,also can custom all kinds of hex nut,square nuts in UNC and Metric threads. Welding nut is a nut is suitable for welding nut, generally can be welded and thicker and welding materials, welding is equivalent to two separate parts into a whole, with a high temperature metal melt together and then cooling, in the middle will join alloy, internal is a function of molecular force, intensity is generally larger than the maternal strength. The test of welding parameters depends on the fusion size of the weld, and the welding parameters should be adjusted according to the fusion size until the defects are eliminated. Of course, the quality of welding is related to welding pre-treatment, dust removal, oil stains and so on. Attempts to sell to foreign markets at the request of friendly factory, Ming Xiao provide lowest ex-factory prices.

Pik casting is a casting method used in industrial applications that require excellence, durability, and high precision. This specialized casting technique involves melting the metal at high temperatures and injecting it into molds, followed by cooling to achieve the desired shape. Pik casting is a method that provides superior performance in the production of parts with complex geometries. Pik casting offers a unique combination of advantages. The use of metals with high melting points enables pik casting parts to withstand extreme temperatures, pressure, and wear. This method allows for the production of parts with exceptional mechanical properties such as high strength, low weight ratio, and high hardness. Additionally, pik casting enables achieving high tolerance levels, ensuring surface quality and geometric precision of the parts.

Thermal spraying processes (as classified in the EN 657 and ISO 14917 standards) offer a wide range of applications within modern surface technologies. Components made from a wide range of base materials can be coated with layers of high-melting-point metals or ceramics to protect them against wear and corrosion. Furthermore, thermally conductive or heat-insulating layers can be applied to highly thermally stressed components. Almost all coating materials that can be produced in powder or wire form can be processed in this way. During thermal spraying, the coating materials are fed into — and melted by — an energetic heat source (fuel gas oxygen flames from combustible gas, arcs or plasmas of noble gases such as argon, hydrogen, nitrogen, helium). The particles, which are either softened or fully molten, are accelerated in the direction of the workpiece and collide with it at high speed (40–600 m/s).

Heat Treatment furnaces MOV are ideal for the treatment of sophisticated materials if high temperatures and an absolutely clean hydro-carbon free atmosphere are required. Due to the ultrahigh vacuum atmosphere as well as the extreme temperature homogeneity and the fully automatic process the furnaces are especially suitable for the economic application in industrial and medical productions, i.e. for brazing of vacuum interruptors, parts of x ray tubes, heat exchangers, parts used in the medical and aerospace industry. Applications: MOV furnaces are universally applicable if heat treatment with particularly high requirements in respect of cleanliness for exacting materials is involved, for example: • Degassing of electric or radiation tube components • Bright- and stress-free annealing of high-temperature alloys • Sintering of high-melting and heavy metals such as tungsten • Production of high-quality fluxless braze joinings of steels, steel-ceramics and many other materials.

AMETEK Specialty Metal Products uses a wrought powder metallurgical process to ensure the highest purity finished products. Our main strengths lie in the processing of Nickel, Iron and Cobalt containing alloys amongst other available materials. The processing of these materials begins with the consolidation of powder through a roll compaction process and followed by a controlled atmosphere sintering. Further reduction of the material is performed solely under cold working temperatures to reduce the introduction of non-metallics and annealing is performed under controlled atmospheres. AMETEK Strip Products are produced in ranges between .002” (0.05mm) and .080” (2.03mm) thicknesses in a full range of tempers and widths to 22” (558.8mm) while maintaining special capabilities to produce materials outside of these ranges for special applications. This process lends itself to the production of small but easily reproducible lots of highly specialized alloys
