T169-2.5 - C-32 Cast Iron TIG Welding Rod 3/32" (2.5mm) - 10lb Tube

Premium C-32 Cast Iron TIG Rods for Precision Repairs

The Josef C-32 Cast Iron TIG Rod is a specialized filler metal engineered for the high-quality repair and joining of cast iron components. Manufactured to strict standards, this rod is essential for professional fabricators and maintenance teams dealing with gray, malleable, or nodular cast iron. The 3/32" (2.5mm) diameter provides excellent control for fine detail work, allowing welders to build up edges, fill porosity, or repair cracks with precision that other processes cannot match.

One of the primary challenges in welding cast iron is the material's brittleness and tendency to crack under thermal stress. The C-32 alloy is formulated with a high nickel content to produce a ductile, crack-resistant deposit that absorbs shrinkage stresses during cooling. This makes it an ideal choice for repairing engine blocks, pump housings, gearboxes, and other critical machinery parts where structural integrity is non-negotiable. The resulting weld deposit is fully machinable, allowing the part to be milled, drilled, or tapped back to its original dimensions after welding.

Packaged in a durable 4.54 kg (10 lb) tube, these 36-inch rods are kept clean and straight, ensuring consistent feeding and arc stability. The TIG process, when used with C-32 rods, offers superior visibility and heat input control compared to stick welding, significantly reducing the heat-affected zone (HAZ) and preventing the formation of hard, brittle martensite in the base metal. Whether you are correcting machining errors in a foundry setting or performing maintenance repairs in an industrial plant, the Josef C-32 Cast Iron TIG Rod delivers reliable, high-strength results.

Key Applications

• Automotive Repair: Ideal for fixing cracked engine blocks, cylinder heads, and manifolds.
