Detailed Description
Grade 7 Ti-0.2Pd titanium rods are titanium alloys with a small addition of the noble metal palladium to commercially pure titanium. The palladium in Grade 7 Ti-0.2Pd titanium alloy rod significantly enhances corrosion resistance in both reducing and oxidizing media. This alloy demonstrates superior resistance to crevice corrosion in high-temperature, high-concentration chloride environments. While maintaining similar properties to commercially pure titanium, Ti-0.2Pd titanium alloy rod finds extensive applications in the chemical industry, particularly in petrochemical processing.

Grade 7 titanium alloy with 0.1% palladium is similar to Grade 2 titanium but offers enhanced resistance to general and localized crevice corrosion in various reducing acid environments, including chlorides, at low pH levels and elevated temperatures from 180°F (83°C) to 500°F (260°C).
Whether manufacturing heat exchangers, reactor vessels, or marine shafting, Grade 7 titanium rods provide long-term durability and tolerance under corrosive and high-temperature conditions. They are widely recognized as one of the most corrosion-resistant titanium alloys available.

FAQ
Q1: How does Grade 7 titanium differ from Grade 2 or Grade 5?
A1: Grade 7 contains 0.2% palladium, significantly enhancing corrosion resistance compared to Grade 2. Grade 5 (Ti-6Al-4V) offers higher strength but lower corrosion resistance.
Q2: Can Grade 7 titanium rods be used in seawater environments?
A2: Absolutely. Grade 7 is one of the most suitable materials for marine applications due to its excellent resistance to crevice and pitting corrosion.
Q3: Do you support custom diameters in small batches?
A3: Yes. We support diameters from 4 mm to 200 mm, with machining and tolerance control per your drawings.
Q4: What surface finish options are available?
A4: We offer polished, peeled, turned, or ground surfaces tailored to your application requirements.
