- AlCrN – Aluminium Chromium Nitride (a.k.a. Alcrona)
TiN
The original yellow/gold coating that provided good wear resistance in many applications, from cutting tools, to punches to injection moulding components to forming tools. Due to it's lower oxidation temperature, it it not used where high heat is generated . The TiN is a low cost, good performance option. It is not to be used when working copper.
TiCN
With the added carbon, the friction is significantly reduced and the hardness increased. TiCN is a thin, tough, hard, low friction coating. It is often used on punches and forming tools and on injection moulding tools when moulding abrasive materials. In metalworking applications, it is compatible with a variety of metals inlcuding stainless steel and aluminium. When TiCN is used without lubrication, movement should be releavtive low to avoid high local temperatures.
TiAlN (Nano)
The TiAlN coating is formed with nano scale particles (therefore our name NANO) and it is a very hard coating with good toughness. It does well on injection moulding parts when abrasives are present, metalworking tooling and punches. It can be used in applications where there is little to no lubrication.
CrCN/CrN
These coating can be applied thicker as it is a tough coating. CrN also has good non-stick properties and can be used for example on pill punches. CrN can be used on a variety of metals but it is partiiculalry suitable when formng copper.
AlCrN
For high stresses and high surface temperatures such as that found in fine blanking. A very hard, durable coating specifically for little to no lubrication and then high surface temperatures are present.
