I've seen a lot of classification, what tools, hardware, machinery, machinery, metallurgy, minerals, etc.,But I always don't know what the hard alloy belongs to. What can I do for you?
Modern ultra hard alloys are produced by sintering of carbides of tungsten carbide and some other elements. It is the hard metal (tungsten, tantalum, titanium, molybdenum, etc.) carbide carbide particles, with one or several iron elements (cobalt, nickel or iron) powder mixed, pressed molding, and then made by sintering.
The original should belong to the tool industry, because the use of hard alloy cutting tools, cutting tools, do some, such as measuring. Now the application of cemented carbide is becoming more and more widespread, and it should be more machining.
Cemented carbide is a powder metallurgy product, mainly used in cutting tools, belonging to the tool industry. Other powder metallurgy products should belong to the machinery manufacturing industry.
