Introduction
Grade 7 titanium alloy contains 0.12 to 0.25% palladium. This grade is similar to Grade 6.The small quantity of palladium added gives Grade 7 titanium alloy enhanced crevice corrosion resistance at low temperatures and high pH.
First,Grade 7 titanium alloy (titanium-palladium alloy) has excellent corrosion resistance in oxidizing media. It can also show considerable corrosion resistance in reducing media and is particularly suitable for improving crevice corrosion resistance in media with high chloride ion concentrations.It can maintain stable performance in high-temperature environments.Grade 7 alloy also has high strength and good mechanical properties, and is suitable for applications requiring high strength.Compared to other metals, titanium alloys have a lower density, making them ideal for lightweight designs.The AL and V elements contained in its make it a high-quality material used in plant biomedicine. Grade 7 titanium alloy has excellent biocompatibility and is widely used in medical fields, such as prosthetic implants and dental implants. Grade 7 has good processing, forming and welding properties.
