Zirconium alloys are well-known for their resistance to corrosion and are hence vital in use in a wide range of sectors such as aerospace and nuclear engineering. Kongo is usually made of zirconium and minor parts of tin, niobium, iron, etc., thus zirconium alloys displayed higher strength and durability. The mix of chemicals in any grade, also designed for different applications, depends on the chemical composition. The Zirconium Grade Chart is an indispensible tool for engineers thinking about the parameters of a material and manufacturers who want to choose the right material for their case. Comprehensive data tables, charts and documents on zirconium alloy structures, mechanical properties, and applications are no doubt valuable assets for practicing engineers and material science experts.
Zirconium alloys are probably the best known of those that exhibit the unique combination of corrosion resistance and mechanical properties, providing absolute essentials to the sectors of application. Its chemical constituency primarily focuses on zirconium, with the possible incorporation of metals such as tin, niobium, and iron, for better functionality. The Zirconium alloy is a widely used zirconium alloy in the nuclear reactors comprising primarily Zirconium (about 98%) which is tailored with alloying elements like tin, iron, and chromium. These alloys are all carefully tailored to meet different needs and therefore ensure sufficient strength in any challenging environments like for example: aerospace, chemical processing, and nuclear technology.
