Unalloyed Commercially Pure (CP) Titanium is represented by four distinct grades, specifically 1, 2, 3 and 4. CP titanium is ordered in relation to the corrosion resistance, formability (ductility) and strength requirements of a specific application. CP titanium ranges from grade 1, which has the highest corrosion resistance, formability and lowest strength, to grade 4, which offers the highest strength and moderate formability. CP titanium end users utilize excellent corrosion resistance, formability and weldable characteristics for many critical applications.
|Grade 1||Grade 2||Grade 3||Grade 4|

|Modulus Of Elasticity||14.9 psi x 106|
|Electrical Resistivity||0.42-0.52 µohms-m|
|Thermal Conductivity||16-22 W/mK|
CP titanium has a tendency to stick, fret or cold weld with drawing dies during processing. Common industry practice to avoid this condition usually employs heavy etching or pickling at finish size resulting in a course or very textured surface. Fort Wayne Metals has developed processing techniques with enhanced surface treatments that require minimal etching at finish size to remove most residual oxide, yielding a cleaner and smoother surface finish. Material can be purchased with this improved surface finish or with a retained water soluble lubricant for applications where lubricity on the wire is required (i.e. weaving applications).
Enhanced surface treatments and processing techniques allow Fort Wayne Metals to offer tighter and more controlled tolerances. The chart in the right column details standard diameter tolerances for CP Titanium in wire and coil forms. Most diameters can be produced to tighter tolerances.
Fort Wayne Metals manufactures CP titanium in straightened and cut bar, coil, strands and cables, flat wire and wire form to support a variety of critical medical and industrial based applications. End uses include:
|Grade||U.T.S. min.||Y.S. min. (2% offset)||% Elongation|
|ksi||MPa||ksi||MPa||(2 in. gage length) min. %|
