Grade 7

Titanium alloys have several advantageous properties that allow them to be used in industries such as automobile, consumer electronics, military, aerospace, medical, marine and sports equipment.

 

Grade 7 Ti-0.15Pd alloy is highly resistant to corrosion in reducing acids and localized attack in a hot halide environment. The presence of palladium helps to increase the corrosion resistance of the alloy. This alloy is similar to grade 2 and has medium strength and ductility.

 

The following sections will be discussed in detail about Grade 7 Ti-0.15Pd alloy.

Physical Properties

Grade 7 contains 0.12 to 0.25% palladium. This quality is similar to class 2. The small amount of added palladium increases the crevice corrosion resistance at low temperatures and high pH values
