Description

1.Feature
○ Material Classification: Original KCF Alloy (Cr-Al-Fe specialized ferritic alloy steel base).
○ Available Dimensions: Standard lengths of 1 Meter (1m); Outer Diameter (Dϕ) customizable from 10mm to 50mm.
○ Core Structure: A specialized bulk metal core wrapped in a 100% uniform, micron-level special heat-treated insulation layer formed through our proprietary oxidation process.
○ Mechanical Strength: High tensile strength and exceptional impact toughness compared to fragile pure ceramics.

2.Advantage
○ Flawless Skin-Effect Insulation: Our advanced heat-treatment ensures the surface insulation layer is extremely dense, uniform, and tightly bonded to the metal core. It will never peel off or crack under high-frequency robotic welding vibrations.
○ Perfect Balance of Toughness & Hardness: Unlike brittle ceramic pins that easily chip or snap when the pneumatic welding cylinder slams down, our KCF rods retain a heavy-duty metal core that absorbs heavy mechanical impacts without fracturing.
○ Excellent Processability: Since we supply them in raw rod/bar form, your workshop can easily cut, turn, and thread them into any complex locating pin shapes (step pins, slot pins) using standard carbide tools before final localized oxidation touch-ups.
○ High Chemical & Thermal Stability: Sustains its structural integrity and insulation performance under continuous high temperature (> 1000°C) resistance welding environments.

3.Benefit
○Eliminate Thread Damage Rates: Flawless insulation completely blocks the welding current from bypassing through the locating pin into the nut threads, achieving a 0% nut-burn defect rate in automotive BIW lines.
○Drastically Reduce Replacement Costs: Due to our optimized Cr-Al-Fe formula, our KCF rods offer excellent anti-friction and wear resistance, lasting significantly longer than cheap imitation alloy bars.
○Flexible Workshop Inventory: By stocking KCF rods, your factory can custom-machine whatever size pin is needed on demand. No need to wait for weeks for expensive pre-fabricated imported pins.
○Boost Hourly Production Output (OEE): Minimizes production line shutdowns caused by pin cracking or electrical insulation breakdown, keeping your automated welding robots running smoothly.

Why Source from Bloom Material?
○Strict Material Source Control: We never use recycled scrap metal. Every batch of our Cr-Al-Fe KCF base material undergoes full spectrographic analysis to ensure exact elemental ratios.
○Advanced Oxidation Furnaces: Our proprietary multi-stage high-temperature gas-controlled oxidation process guarantees the depth and insulation resistance of the KCF layer.
○Complete Inspection: Every single rod is checked for surface micro-cracks and straightness before being packed in heavy-duty protective wooden cases for international shipping.
