Alloy of tungsten, Nickel, molybdenum
Supplier — AvekGlob Company — offers at an affordable price from the manufacturer alloys of tungsten with nickel and molybdenum. The supplier guarantees the timely delivery of products to any address specified by the consumer /
Alloys of tungsten with nickel and molybdenum belong to the group of heavy tungsten alloys. They are distinguished by a high degree of chemical purity and are manufactured in the form of metal powders, submicron powders and granules for applying chemical vapor deposition or physical vapor deposition. The heat resistance of such alloys is lower than that of pure tungsten — no more than 600 0 С.
Urgency of application
Tungsten alloys with nickel and molybdenum are used in military technology, pharmaceuticals, food processing and optical equipment.
Primary applications include the production of precise bearing assemblies, ballast systems, radiation protection installations and molds for precision injection molding. Typical products that are made from these alloys are ballast systems, vibration and recoil reduction devices, X-ray shielding devices, aerospace parts. Addition of molybdenum increases the resistance of the alloy to high temperatures.
Tungsten — not less than 93%;
Molybdenum — no more than 2.5… 4.0%;
Nickel — 4… 6%.
The total content of nickel, molybdenum and iron in an amount up to 10% is allowed.
