Northwest Institute for Nonferrous Metal Research (NIN) is one of the main units for the R & D of titanium alloys in China. NIN devotes to research and development of titanium alloys for more than 40 years, as well as for Ti alloy industrial manufacture. NIN has made research and developed nearly 60 kinds of conventional Ti alloys, and these alloys are extensively applied to industrial manufacture. NIN also designs and develops many kinds of new titanium alloys, for example TC21, Ti75, Ti-B19, CT20, Ti12LC, TP650 and so on. Some of these alloys are used or will be used and some alloys are industrially manufactured. This paper reviews the conventional and new alloys developed by NIN and their industrial manufactures.
