Hemi Metals, located in Hamilton, New Zealand, is a reputable manufacturer and supplier of high-performance Titanium Grade 7 Bars and Rods, specifically designed for critical applications that require corrosion resistance. This titanium grade is renowned for its exceptional ability to withstand harsh chemicals and marine conditions, thanks to its alloying with palladium, which boosts its durability. Hemi Metals guarantees precise dimensions, rigorous quality checks, and adherence to international standards with every batch they produce. These bars and rods find extensive use in chemical processing, marine engineering, heat exchangers, and aerospace applications, where reliability and resistance to corrosion are essential.
Titanium Grade 7 is mainly made up of commercially pure titanium, with a carefully controlled addition of about 0.12–0.25% palladium, which greatly improves its corrosion resistance. It boasts a tensile strength of around 345 MPa and a yield strength close to 275 MPa, along with impressive elongation and impact toughness. This alloy is lightweight, non-magnetic, and highly resistant to crevice corrosion and reducing acids. Titanium Grade 7 bars maintain excellent mechanical stability over a broad temperature range and excel in challenging chemical and marine environments.
