2 Years’ Warranty for Cobalt Alloy Refractaloy 26 UNS R30188 in Monaco

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 Specific 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, largely composed of nickel (up to sixty seven%) and copper, with tiny quantities of iron, manganese, carbon, and silicon. More powerful than pure nickel, Monel alloys are resistant to corrosion by quite a few agents, like promptly flowing seawater. They can be fabricated quickly by very hot- and chilly-working, machining, and welding.[2]

Monel was made by David H. Browne, main metallurgist for Global Nickel Co. Monel alloy four hundred is a binary alloy of the identical proportions of nickel and copper as is found naturally in the nickel ore from the Sudbury (Ontario) mines and is thus thought of a puritan alloy. Monel was named following business president Ambrose Monell, and patented in 1906.[three] Just one L was dropped, for the reason that loved ones names were being not allowed as trademarks at that time.[one] The title is now a trademark of Specific Metals Corporation.

How to weld nickel alloys like hastelloy, inconel, etc. Nickel alloys have a low thermal conductivity and so limiting heat input and using lower amperage than would be used for stainless is one key to making good nickel alloy welds.
