KCF PIN VS. ALUMINUM-OXIDE COATED PIN WHAT IS DEFERENT ABOUT INSULATED OUTER SURFACE?KCF is not a coating, it is the actual material. The KCF material contains aluminum and when specially heat treated, the aluminum comes to the surface and joins with oxygen to form aluminum-oxide. The surface of the KCF pin is 20-30micro meter thick. This process makes the pin very strong because it is all same the material, even insulated surface. Aluminum-oxide coating is steel layered with an aluminum-oxide compound. It is 2-3micro meter thick, even 10micro meter is not as strong as KCF because it is layered. THE DANGERS OF ALUMINUM-OXIDE COATINGWe using aluminum-oxide coating on hard material, this is a danger point. With coating it is easy to take of the insulating skin. Even past its life the guide pin still looks new, this gives the appearance that the pin is in good condition, when actually it should be replaced with a new one. This can cause failure. Insulated skin of a KCF pin has a life of 5-10 times longer than aluminum-oxide coating. Even if KCF pin looks broken, insulated skin is still working. (The KCF material can not control hardness.) EXPERIENCES OF JAPANJapan does not use aluminum-oxide coated pins due to the reason stated in the previous paragraph. Currently, Japan only uses KCF and Ceramic pins. Insulated skin is necessary for Projection welding pins. KCF IS EXPENSIVE, DELIVERY IS SLOW? (Made
in USA)Due to special technology, KCF has had to be imported from Japan. Now America has one company, which uses , that produces KCF pins, they began production the first of 2001. NOW, exchange rate is not a concern, reasonable and stable prices, stable delivery, short lead times on special shapes, and technical support are available. Weldparts, Inc.
