At Giometal, mill certificates provide documented evidence of our Ti-6Al-4V ELI titanium’s material specification. Issued by the material mill, these certificates record the chemical composition, mechanical properties and stated conformity to ASTM F136 for the material identified in each document. ASTM F136 specifies requirements for wrought Ti-6Al-4V ELI titanium alloy intended for surgical implant applications. For professional partners, these records provide a clear basis for reviewing the raw material used in our titanium body jewelry.
