Main feature
It has low internal stress, relatively high toughness, good lubricity and wear resistance. It has remarkable effect on punching die and stretch forming die
Scope of application
1.Precision mold: in the metal stamping and bending mold, continuous high-speed punching die and stretch forming die has a significant effect.
2. Cutting tools: drill, tap, milling cutter, hob cutter, circular saw blade and other cutting tools.
三、The alumina layer formed in the TiAlN/AlTiN coating can effectively increase the high-temperature working life of the tool. Tungsten carbide tools mainly used for dry or semi-dry cutting can choose this coating. Depending on the proportion of aluminum and titanium contained in the coating, AlTiN coatings provide a higher surface hardness than TiAlN coatings, making it another viable coating option for high-speed machining.
