Product Overview

45CT Welding Wire (equivalent to Metco 8500) is a high-performance NiCrTi alloy wire specifically engineered for demanding welding applications. This nickel-chromium-titanium wire offers outstanding corrosion resistance and thermal stability in high-temperature environments. It is commonly used in industries such as aerospace, marine, power generation, and chemical processing for welding components that must endure extreme heat, oxidation, and mechanical wear.

45CT welding wire is designed to provide smooth, stable arcs, excellent wetting characteristics, and consistent results in TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding. With its ability to maintain structural integrity at elevated temperatures, it is the ideal choice for components exposed to continuous heat cycles and aggressive conditions.

Chemical Composition (Typical)

Fully conforms to NiCrTi alloy standard; equivalent to Metco 8500.
