CNC milling a super alloy like Nimonic
Some materials lend themselves easily to CNC milling. Others demand greater technical skill and specialist equipment. And then there are metals that demand the very best of a machining company. These are not surprisingly called super alloys. Nimonic is a well-known example.
Super alloys consist of various elements, many of which occur in high percentages. Iron is often the base element, and other metals are added to it, such as nickel, cobalt, chrome, molybdenum and vanadium.
Such a super alloy, based on iron, can be regarded as a special kind of stainless steel. Examples include Haynes 556 and types of Incoloy. The added hardening elements make these alloys strong, heat proof, corrosion and contraction resistant.
There are also nickel-based super alloys, such as Hastelloy, Inconel and Nimonic, all in various forms.
Haynes 188, Stellite 6B and V36, for example, have cobalt as the base element.
Their mechanical, chemical and thermal characteristics make super alloys suitable for applications which place high demands on hardness and corrosion resistance. But this also means that CNC milling these metals needs special equipment and methods.
At Landes we have extensive experience in handling super alloys. We are even able to process these hard to machine materials down to micrometre accuracy. This is why our motto is: “any shape in any metal¨.
