Experimental casting of monel alloy Czech Republic Liberec

Experimentální odlévání monelu na katedře strojírenské technologie při TU v Liberci - Monel je slitina niklu a mědi. Název Monel je registrován jako trademark americké firmy Special Metals Corporation. Monel vyrobil v roce 1901 Robert Crooks Stanley, slitinu pojmenoval po tehdejším prezidentu firmy Ambrose Monellovi. Monel vykazuje výborné mechanické vlastnosti a chemickou odolnost v náročném prostředí, např. v dlouhodobém kontaktu se slanou vodou, ale i v chemickém průmyslu. Často bývá využit tam, kde již nedostačují vlastnosti nerezových ocelí. Monel is a group of nickel alloys, primarily composed of nickel (up to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. Stronger than pure nickel, Monel alloys are resistant to corrosion by many agents, including rapidly flowing seawater. They can be fabricated readily by hot- and cold-working, machining, and welding.[2] Monel was created by David H. Browne, chief metallurgist for International Nickel Co. Monel alloy 400 is a binary alloy of the same proportions of nickel and copper as is found naturally in the nickel ore from the Sudbury (Ontario) mines and is therefore considered a puritan alloy. Monel was named after company president Ambrose Monell, and patented in 1906.[3] One L was dropped, because family names were not allowed as trademarks at that time.[1] The name is now a trademark of Special Metals Corporation.
