The SurfAlloy Process

An electronically controlled pulsed-arc micro welding process which metallurgically bonds tungsten carbide uniformly to a steel substrate. Our tungsten carbide coating works at near-ambient temperatures to ensure that your work piece doesn’t become embrittled or warped; we can even surface treat hardened parts. We can treat the same tools many times, virtually eliminating your need to buy replacements.

SurfAlloy Grades

Benefits: - Tools can be resurfaced not replaced - Increased gripping power - Carbide coating increases tool life - Treatment cost a fraction of replacement tooling - Decreases downtime - Tungsten carbide coating surface hardness is up to 74 Rc - Excellent uniformity - No thermal distortion due to the low heat input process - True metallurgical bond - Carbide coating will not chip, peel or flake - In most cases clamping pressure can be reduced - Increase machining rates with additional gripping power - Tools can be accurately masked off - Increase or decrease the coefficient of friction

Turnaround Time: - Normal Service 2-3 days - One Day Service 10% Additional - Same Day Service 25% Additional

Applications: - Screw Machine Collets - Workholding Details - Forging Dies - Tube Bending Clamps - Testing Grip Wedges - Milling Cutter - Trepan Cutter - Dimensional Restoration - Cold Heading Fingers - Feed Rolls - Die Casting Dies
