Product Description

Product Overview

HRA90 3mm Tungsten Carbide Nozzle is a precision component designed for coil winding machines, manufactured from super hard alloy with hardness exceeding HRA90 and anti-bending strength over 2300N/mm².

Key Advantages

High Wear Resistance: Hardness value of 1800-2200 Vickers, approximately 3 times that of case-hardened steel
Scratch-Proof Design: Mirror-finished surfaces with roughness ≤ 2-4 micro inches Ra prevent wire insulation damage
Precision Straightness: Concentricity within 0.01mm and wire exit concentric to locating within 0.02mm
Accurate Exit Radii: Controlled to ±0.025mm for consistent wire exit angles between coils

Technical Specifications

The nozzle features mirror surface treatment on terminals and inner/outlet surfaces to eliminate enameled wire scraping.
