Excellent Insulativity KCF Material Rods For Automobile Industry Bolt Welding

         Rods for making guild sleeves for bolt welding in automobile industry

1 . KCF Materials is a kind of special alloy materials, when it has been heat treated with 1220C temperature, there will be a good insulating layer with thickness about 8-15um appeared on its surface.

     This alloy materials is widely used in resistance welding industry, it can be made into insulated location pins(guid pins) and Location bushings(guid sleeves) for nut welding or bolt welding .the guid pins and sleeves have good durability, excellent insulativity, super surface hardness and anti-abrasive capability.

     We can offer KCF alloy Rods with diameter of 8-85mm and length is about 1m or longer. After our special treatment, there are about 3 oxidation layers created, and when observing under electric microscope 10000 times, you can see its uniform microstructure and the layers are so closely to each other. Which offer better performance for anti-resisting and insulativity. We also can manufacture many sizes of guid pins and guid sleeves for our customers. We also can make based on the customer’s requirements.
