ASTM F1684 Iron Nickel Alloy Wire Alloy Welding Wire 1.6mm 2.0mm AWS
Invar Alloy exhibits extremely low expansion around ambient temperatures, making Invar Alloy particularly useful in applications where minimum thermal expansion and high dimensional stability is required, such as in precision instruments like optoelectronic devices, optical and laser benches, electronics, and other kinds of scientific instruments.
Product Description and Application
45CT (PS45,NiCr44Ti)Sprayed Wire is used for fusion gas welding and tungsten inert gas welding, surfacing nickel-chromium alloy on Nickel iron chromium steel tubes and casting repair welding. The weld metal has the ability to resist high temperature corrosion and the smoke corrosion containing sulfur and alum in the air.
