Because stainless steel requires an additional insulator and ceramic is generally too brittle, Dengensha America Corp. wanted to find a superior material. ACT is that material. This surface allows the pin to be used without additional insulation and has been shown to outlast KCF and ceramic coated pins nearly 2 to 1 and is far less expensive than ceramic composition pins, providing the lowest possible cost per nut weld.
Features
High quality steel is alloyed with chromium
Superior electrical insulation characteristics
The most precise dimensions can be obtained
Insulation layer is virtually pore-free (profilometer reading of 35 Ra)
Insulating film is metallurgically stable up to 2000° F
Insulating film is uniformly distributed throughout the shape of the pin
