Introduction
Titanium alloys are widely used across various industries due to their excellent properties, including high strength-to-weight ratio, good corrosion resistance, and biocompatibility. They find applications in automotive, consumer electronics, military, aerospace, medical, marine, and sports equipment sectors.
Grade 7 Ti-0.15Pd alloy is a special type of titanium alloy that offers enhanced resistance to corrosive environments, especially in reducing acids and hot halide media. The addition of palladium significantly improves its corrosion resistance. This alloy is similar to Grade 2 titanium in terms of mechanical properties, offering moderate strength and good ductility, making it suitable for a wide range of industrial uses.
This section provides a detailed overview of the Grade 7 Ti-0.15Pd alloy, covering its chemical composition, physical, mechanical, and thermal properties.
