Ti-6Al-4V Grade 5
VerifiedmetalUNS R56400· 6-4 Grade 5
Ti-6Al-4V Grade 5 is a two-phase titanium alloy containing aluminum and vanadium alloying elements, representing the most widely used titanium alloy in industry due to its excellent balance of strength, weight, and corrosion resistance. It is the workhorse material for aerospace structures, medical implants, and chemical processing equipment, chosen by engineers specifically for applications requiring high strength-to-weight ratio, superior biocompatibility, and reliable performance in demanding thermal and corrosive environments where conventional steels or aluminum alloys fall short.

Quality & Standards
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
