These titanium rods are the strongest of the commercially pure titanium alloys, Grades 1 through 4, and resist corrosion better than Grade 5 titanium. However, they’re not as strong as Grade 5, and they won’t bend or form as easily as lower grades. Use them in chemical processing and marine environments. Nearly 99% pure, these rods won’t corrode from chlorides or oxidizing acids, such as hydrochloric and sulfuric acids. They also stand up to alkalis, such as hydroxide and ammonia. With more iron and oxygen than lower grade titanium, these rods are lightweight as well as strong. They also withstand impacts at low temperatures.
