Bloom welding is the manufacturer of the KCF bars,and we also make the KCF guide pins.We offer different sizes guide pin,locating pin,bushing,sleeve.Our material include KCF alloy material,ceramic coated,Zirconia ceramic,Silicon nitride ceramic etc.We not only can make the standard size and also can make the KCF pins according to your drawings.Welcome your inquiry.
We produce and supply all kinds of resistance welding accessories,welding electrode,electrode tips,cap tips,electrode holder,electrode arm,adapter,welding wheel,straight shank,bent shank,KCF guide pins,KCF sleeve,tip dresser tool,welding tester.
2. Properties
Code | Composition(wt%) | Tensile strength(N/mm2) | Yield strength(N/mm2) | Elongation(%) | Features | Application |
KCF | Cr20,Al3,Fe Bal | 539 | 392 | 15 | Oxidation resistant | Brazing jigs,Guide pins for projection welding |
We offer various sizes of KCF guide pin and KCF sleeves. The standard kcf pins are always in stock.Also supply customized pins according to your drawing.With excellent insulation performance and long-life,our kcf guide pins are directly or indirectly used on GM,VW,TOYOTA etc.automotive welding factory.
Pin Material: KCF,AL2O3,ZrO2,Si3N4,Ceramic,Stainless Steel etc.
KCF Pins Diameter:M4,M5,M6,M8,M10,M12…
Application: KCF guide pins are widely used on projection welding,nut welding,stud welding
Good insulation performance
Excellent wear resistance ability
High temperature anti-oxidation performance
Good heat shock performance
KCF material is a special metal material.Through special heat treatment process and process temperature range of 1000-1500 degree adjustment,the surface can generate a layer of 10-32μm thick high-quality insulation layer,the insulation layer and the alloy matrix has a good ability to combine.So that the material takes into account the good wear resistance and high insulation resistance.The material in the mechanical processing after formation of a variety of parts,after cleaning and heat treatment with insulation,wear and anti-oxidation of the three functions of the product.This material is mainly used in resistance welding equipment.
We generally use ceramic guide pins as a welding nut positioning pin, but because of the toughness of ceramics is poor, fragile, so now KCF guide pin instead of ceramic is more and more popular.
| Ceramic (solid) | Traditionally Silicon Nitride -fully insulated. | Grey, White, Beige, Blue | High intial cost but will last longer than any other pin when conditions allow. Sosceptible to damage. Repels weld spatter. |
|---|---|---|---|
| KCF | A special heal treated alloy with a hard,insulating skin | Grey / Black | A low cost pin with a reasonable lifespan |
