Projection Welding Insulation Sleeves For Automobile Manufacturing Industry
1 . Descriptions:
KCF Guide Sleeves have been used in Resistance Welding applications
for several decades. KCF is not a coating, it's the actual
material. KCF Alloy is a Ferritic Stainless Alloy, which adds
Chrome, Aluminum, and other special elements. When the KCF material
is heat treated via a special high temperature process, the
Aluminum comes to the surface and joins with oxygen to form
Aluminum-Oxide, creating an insulated skin on its surface. This
process makes the pins and sleeves very strong because it's all
same the material, even the insulated surface. The surface of the
KCF pin/sleeve is 20-30 micrometers thick.
