KCF Special Alloy Welding Pin / Centering Pin / Guide Pin / Location Pin
Bloom KCF material is a kind of special alloy materials,when it has been heat treated with 1220℃ temperature,there will be a good insulation layer with thickness of 8-15um appeared on its surface.
This alloy material is widely used in resistance welding industry,it can be made into insulated location pins (guide pins) and location bushings (guide sleeves) for nut welding or bolt welding.The guide pins and sleeves have good durability,excellent insulativity,super surface hardness and anti-abrasive capability.
We can offer KCF alloy rods with diameter of 9 to 85mm,and length is about 1m or longer.Aafter our special treatment,there are about 3 ocidation 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-resistance and insulativity.We also can manufacture many sizes of guide pins and guilde sleeves for our customers.We also can make based on the customer's requirements.
Used as projection welding(spot welding),KCF pins can completely avoid the passage of unnecessary current,avoid sparks between
the pins and the workpiece,and the high wear resistacne feature allows the workpiece to be accurately positioned for a long time.The
welded workpirece maintains a very high qualtiy and high yield.And because of the avoidance of sparks ,the workpiece don't need to add extra hole.
