High-Performance KCF Alloy Rod | Surface Insulation Layer 8-15μm | For Nut Welding
High-performance KCF alloy rods designed for manufacturing insulating pins and sleeves. Featuring a specially treated surface layer for superior insulation and exceptional heat resistance, our KCF bars ensure precise nut/bolt positioning while preventing current shunting during the welding process.
Description
Why Choose BLOOM KCF Alloy Bars?
Our KCF alloy is a ferritic stainless steel base material, specially processed through a unique heat treatment at 1220°C. This creates a high-quality 8-15μm thick insulation layer on the surface. It is the preferred choice for automotive and electronics manufacturing where welding precision is non-negotiable.
Key Features:
Superior Insulation: Prevents unwanted current flow through the locating pins.
Heat & Oxidation Resistance: Maintains structural integrity under high-temperature welding cycles.
Extended Service Life: Highly resistant to mechanical wear compared to ceramic alternatives.
Excellent Machinability: Can be precisely machined into complex shapes before final treatment.
