Core Advantages
Stable Insulation Skin: Bloom’s unique heat treatment process creates a deep, black insulating layer that won’t peel or flake off during heavy-duty welding.
Superior Toughness: Compared to brittle ceramics, KCF material has the mechanical strength of an alloy, making it resistant to impact and cracking.
High Wear Resistance: Designed for high-volume production lines, our KCF rods offer a long service life, reducing downtime and replacement costs.
Excellent Machinability: Our KCF rods can be easily machined into various shapes (M4, M5, M6, M8, M10, M12 pins) according to your specific blueprints.

Application Scope
Automotive Manufacturing: Widely used in Body-in-White (BIW) lines for projection nut and stud welding.
Resistance Welding: Perfect for making guide pins, bushings, and sleeves that require electrical insulation.
Brazing Jigs: High-temperature resistant components for specialized jig systems.

Customization & Service
At Bloom, we don’t just sell rods. We understand the precision required in the automotive industry：
1. Custom Shapes: We can provide both raw rods and finished KCF pins based on your drawings.
2. Strict Quality Control: Every batch is tested for insulation resistance and surface hardness.
3. Direct Factory Price: Save costs by sourcing directly from the production line.
