Is there a significant difference between AlTiN+ and TiAlN?
Yes. AlTiN+ (Aluminum Titanium Nitride) has superior properties when compared with TiAlN (Titanium Aluminum Nitride). A TiAlN coated tool may last up to 10x longer than an uncoated tool. When using an AlTiN+ coated tool, it may last up to 12-14x longer than an uncoated tool depending on the application. The maximum temperature for TiAlN is approximately 1450 degrees Fahrenheit, whereas AlTiN+ can withstand up to approximately 1652 Fahrenheit. AlTiN+ has a hardness (Vickers) of 4500 (90 Rc) while TiAlN has a hardness of merely 2800 (85 Rc). When working with harder materials like steel, stainless steel, and high-temperature alloys, it is beneficial to use an AlTiN+ coated tool for higher cutting speeds and nano hardness.
