Commercially Pure Titanium

ERTi-1

ERTi-1 is the lowest strength unalloyed, or commercially pure titanium available.  It is normally used in applications where ductility is paramount.  Applications include explosive cladding, expanded metal, and deep drawing applications.  As with all titanium alloys, ERTi-1 is extremely reactive above 1000°F and extra precaution must be taken to have a successful weld.  ERTi-a can be welded by the GTAW, GMAW and plasma arc processes.

ERTi-2

ERTi-2 is the “workhorse” of titaniums in the commercially pure titaniums  available.  It is normally used in applications such as pressure vessles, pipes, columns, tanks, shafts, valves, and fittings.  As with all titanium alloys, ERTi-2 is extremely reactive above 1000°F and extra precaution must be taken to have a successful weld.  ERTi-2 can be welded by the GTAW, GMAW and plasma arc processes.

ERTi-5

ERTi-5 (Ti 6Al-4V) is also know as 6-4 titanium.  It is the most common and widely used titanium alloy, due to it's relatively low cost and easy availability.  Weldability is good and it can be heat treated to a higher strength  or toughness.  ERTi-5 is used in aircraft components such as landing gear, wing spars, and compressor blades.  Corrosion resistance is comparable to the ERTi-2.  It can be welded by the STAW, GMAW and plasma arc processes.

ERTi-7

ERTi-7 has the same mechanical properties as the ERTi-2 but has the addition of palladium.  This improves corrosion performance under mildly reducing conditionsor where crevice or under-deposit corrosion is a problem.  For this reason ERTi-7 can be considered for welding grade 2 or grade 16 titanium where improved corrosion performance is desired.  It can be welded by the GTAW, GMAW and plasma arc processes

• Classification: ERTi-7

ERTi-12

ERTi-12 is an intermediate strength grade of titanium orginally developed to provide enhanced crevice corrosion resistance in high temperature brines, but at a lower cost than the ERTi-7. ERTi-12 has better elevated temperature than ERTi-2 and is sometimes specified for pressure vessels or piping for its superior strength alone.  It can be welded by the GTAS, GMAW and plasma arc processes.
