What is the difference between Incoloy and titanium?
Inconel
Inconel is a material optimized for the harshest usage conditions in manufacturing, while titanium is a chemical element with the symbol Ti and atomic number 22. It is a lustrous transition metal with a silvery appearance, low density and high strength.

Inconel
Inconel alloys include:
Inconel 600: solid solution strengthening
Inconel 601
Inconel 625: Acid resistant, good weldability. The LCF version is usually used for corrugated pipes.
Inconel 690: low cobalt content and low resistivity for nuclear applications
Inconel 713C: Precipitation hardened nickel-chromium based casting alloy
Inconel 718: gamma double element strengthened, with good solderability
Inconel 751: Increased aluminum content improves fracture strength in the 1600 °F range
Inconel 792: Increase aluminum content to improve high temperature corrosion performance, especially for gas turbines
Inconel 939: Gamma strengthened to improve solderability
