ASTM Grade 1 pure titanium bar is the highest purity industrial titanium bar with optimal plasticity and form-ability, offering exceptional corrosion resistance. Corresponding to the Chinese national standard TA0/TA1, it is a lightweight, corrosion-resistant material characterized by low strength, high toughness, and ease of machining. It is widely used in medical, marine, chemical, aerospace, and other industries.
Basic information and implementation standards:
1. Materials: Gr1 or TA1
2. Primary Standard: ASTM B348 (Titanium and Titanium Alloy Bars and Billets),AMS 4928
3. Chemical Composition (wt%, Annealed Condition(M)):
