Grade 7 titanium rods have excellent machining, forming and welding properties. Since Grade 7 titanium rods are made from pure titanium with a small amount of the precious metal Pd, the alloy produces excellent corrosion resistance to acidic media. However, the cost of Grade 7 titanium alloys is relatively high due to the presence of the precious metal palladium.
