Commercially pure grade 2 titanium

grade 2 titanium Characteristic and Application

1. Commercially Pure Grade 2 Titanium

Alternate Names: CP Grade 2 Titanium, CP 2, Grade 2, CP 40

Description: Commercially Pure Grade 2 Titanium is one of the most
common Grades of unalloyed Titanium. In Commercially Pure Titanium,
the mechanical properties are controlled by the chemistry input; higher
amounts of Nitrogen, Oxygen, and Iron will increase strength properties.
CP Grade 2 is higher in strength than CP Grade 1, but lower in strength
than CP Grade 3 and CP Grade 4. It is sometimes referred to as “CP 40”
due to its approximate yield strength. CP Grade 2 Titanium typically
comes in the Annealed condition. It is an attractive Grade of Titanium due
to its excellent corrosion resistance, good formability, and limited
strength. It is used in a variety of industries such as chemical, marine,
medical, recreational, and aerospace.
Machinability: Low cutting speeds, heavy feed rates, sharp tools, and
ample cutting fluid are prescribed.

CP Grade 2 Titanium is available in the following Product Forms:
Round Bar (Rod), Plate, and Sheet
