Titanium and pure titanium are two distinct titanium materials, exhibiting notable differences in composition, performance, and applications.

Differences:

Composition:

Pure Titanium: Pure titanium refers to materials containing over 99.0% titanium elements. Common grades of pure titanium include Gr1, Gr2, Gr3, etc. Titanium Alloy: Titanium alloy is formed by alloying titanium with other metal elements (such as aluminum, iron, nickel, etc.), creating materials with specific properties. Common titanium alloys include Ti-6Al-4V, Ti-6Al-4V ELI, etc. Performance:

Pure Titanium: Possesses excellent corrosion resistance and biocompatibility but relatively lower strength and hardness. Titanium Alloy: Exhibits higher strength, hardness, and corrosion resistance, making it more suitable for high-strength and special environments. Applications:

Pure Titanium: Mainly used in fields with high requirements for biocompatibility, such as medical implants, biomedical devices, and structural components in aerospace. Titanium Alloy: Widely employed in aerospace, chemical engineering, energy, automotive, and other industries, especially in engineering applications that demand higher strength, lightweight, and corrosion resistance. Overall:

Pure Titanium emphasizes biocompatibility and excellent corrosion resistance, suitable for medical applications, among others. Titanium Alloy, by alloying, enhances strength and hardness, making it more suitable for engineering applications with higher mechanical performance requirements. When choosing materials, the specific application scenarios and performance requirements should dictate whether to use pure titanium or titanium alloy."
