What Is ZT610 Alloy and How Does It Compare to Hastelloy C? Best Alloy for High-Corrosion Extrusion Barrels

Which material should you choose for extrusion barrels under high-corrosion and high-temperature conditions? ZT610 nickel-copper alloy, independently developed by ZHITIAN, is engineered to replace Hastelloy C for twin screw extruder barrel applications. Produced using vacuum hot-press sintering, ZT610 features high density, low porosity, and uniform metallurgical structure. Compared to Hastelloy C, it delivers significantly enhanced wear resistance and corrosion performance, making it ideal for highly corrosive industries such as chemicals, pesticides, fluoropolymers, chlorinated polymers, organic salts, and marine applications.

What makes ZT610 different from Hastelloy C?

ZT610 achieves a hardness above HRC45, whereas Hastelloy C offers only HRC20-21. In abrasion testing, ZT610 performs 4 times better under identical conditions. In terms of corrosion resistance, ZT610 achieves 1.5 to 2 times the resistance of Hastelloy C, making it suitable for long-term, high-shear, and chemically aggressive extrusion processes.

ZT610 Key Benefits:

• High hardness and superior wear resistance (HRC ≥ 45)
• Nickel-copper matrix improves corrosion performance by forming solid solutions
• Added molybdenum and chromium for enhanced chemical resistance
• Vacuum hot-pressed for high structural density and stability
• Specially designed for twin screw extruder barrel applications

How ZT610 Works

ZT610 forms a high-density solid solution structure at elevated temperatures, thanks to the full miscibility of nickel and copper. With the addition of molybdenum and chromium, the alloy resists both intergranular corrosion and pitting under acidic or alkaline conditions, ensuring long-term stability.
