10kg – 2.5mm ENi55 Cast Iron Nickel Stick Electrodes: Premium Repair Solution for Heavy Castings

Product Description

Engineered for industrial-grade cast iron repair, these Taurus ENi55 nickel stick electrodes deliver exceptional performance for heavy-section castings. With 55% nickel content, they balance economy and machinability while offering superior ductility and phosphorus tolerance compared to 99Ni alternatives. Ideal for critical repairs requiring minimal fusion line cracking, this 10kg pack (10 x 1kg) meets global standards for reliability in demanding applications.

Core Specifications

Core Performance

? Superior ductility for high-stress castings
? Excellent phosphorus tolerance in base materials
? Reduced fusion line cracking via low expansion coefficient
? Easy post-weld machining compared to 99Ni electrodes
? Stable arc performance at 100-120A operating current

Application Scenarios

Perfect for repairing large cast iron components including: industrial machinery housings, engine blocks, pump casings, and heavy equipment parts. Ideal for foundries, automotive repair shops, and manufacturing facilities requiring reliable, cost-effective cast iron welding solutions.

Competitive Differentiation

Unlike 99% nickel electrodes, ENi55 offers:
? 30% lower material cost without sacrificing critical properties
? Enhanced machinability for post-weld finishing
? Better tolerance to casting impurities (phosphorus)
? Reduced thermal stress cracking during cooling

Quality Assurance

Manufactured to international standards (ISO 2560/AWS A5.1) and backed by Taurus’ reputation for industrial-grade welding consumables. Each batch undergoes rigorous quality testing to ensure consistent performance and reliability in demanding environments.

FAQ

Q: What current settings are recommended?
A: Optimal performance at 100-120 amps DC reverse polarity.

Q: Can these electrodes be used on all cast iron types?
A: Yes, particularly effective on gray and ductile cast irons with phosphorus content up to 0.15%

Q: Is preheating required?
A: Recommended for thick sections (preheat to 200-300¡ãC) to minimize stress cracking.
