Terry Pratchett's character, Jeremy Clockson, claims that Invar is more expensive than gold. its an exotic nickel steel alloy that has a CTE near nothing, I am guessing its heavy but wondering why if its the same weight as steel that we dont make tubes out of it. The conventional Invar alloy is used generally for its optimum low expansion properties. Hey guys Im back! In fact, Invar is about five times more expensive than 304 stainless steel. The Invar FeNi36 alloy is ductile and easily weldable, and machinability is similar to austenitic stainless steel. Most alloys cannot be Alloy 36 K93600 36.0 64.0 hardened by heat treatment and best machining is obtained Alloy K K94610 29.5 53.0 17.0 in cold-drawn or cold-drawn and stress-relieved conditions. It has a slightly lower coefficient of thermal expansion than Free Cut Invar. Does anybody have any experience of casting and/or machining Invar 36? B of the spec (the only one available). Registration Invar 36 is a 36% nickel-iron alloy possessing a rate of thermal expansion approximately one-tenth that of carbon steel at temperatures up to 400°F(204°C) Applications This alloy has been used for applications where dimensional changes due to temperature variation must be minimized such as in radio and electronic devices, aircraft controls, optical and laser system, etc. The alloy also retains good strength and toughness at cryogenic temperatures. I'm afraid I must disabuse forum members of this statement, lest they start taking apart their clocks and watches in the hope of scrapping the Invar components. The name Invar comes from the word invariable, due to its relative lack of expansion or contraction with temperature changes. Invar® end uses include glass sealing, clocks, laboratory devices, creep gauges, shadow-mask frames and valves in motors. I've never milled this before. I'm a bit nervous. machinability and smoothest finish. It has thermal mass benefits, for faster autoclave cycles each time the customer is curing a part. Any ideas on feed and speed, I was thinking 130SFM at .002-.003" per rev. ... Register for the world’s largest manufacturing technology forum for free today to stay in the know. Together with a near zero thermal expansion Alloy 36 provides a high retention of strength and toughness at cryogenic temperatures, making it ideal for a range of both low temperature and low expansion applications. ;-) I hope everyones holidays are going well. Is it stable? This Forum; Advanced Search; Welcome to eMastercam. I have a project coming up that is going to require me to turn 1/4-28 invar screws from bar stock.
