TiN

TiN is a sort of coating with gold yellow color. The TiN coating has high hardness, good wear resistance and proper oxidation resistance. It is suit for high speed cutting. TiN has high performance/cost ratio. It is generally used to prolong the lifetime of the cutting tools, especially for the cutting tool used to cut the soft products like brass and low carbon steel. TiN can be deposited onto lathe cutter, milling cutter, drills, screw tap, gear hobber, forming moulds, press dies, extrusion dies and die-casting moulds, parts of moulds, wear resistance parts, mechanical parts, decorative parts. TiN is the best choice for cutting iron products, plastic forming moulds and wear resistance products.
