It is reported that in January 2004, Aichi Steel Corporation of Japan developed a new type of titanium alloy "ASTA, which is both flexible" and "high-strength". It recently began to sell samples, and it officially sold its products in April. According to different uses and shapes ,Adjusting the composition and composition of products with “ASTAL†and “ASTA2†with different production strength and longitudinal modulus.The estimated annual sales amount is about 500 million yen.The new alloy is β-alloy of Ti-Nb-Mo alloy and other alloys. The system (alpha alloy, alpha+beta alloy) has high strength, high processability, and small longitudinal elastic modulus (less numerical values ​​are better), but if the characteristics are to be improved, other characteristics will be deteriorated. The company improved various properties by adding a third and fourth element, etc. The new alloy has a modulus of longitudinal elasticity that is comparable to that of the well-used Ti-6A1-4V alloy. The latter's 1/2, about 45 Gpa, shows a value close to that of magnesium alloys, with a tensile strength of about 1250 MPa, an increase of 20%, and at the same time an increase of about 2% over the elastic deformation of common metallic materials.The price of the new alloy is Ti-6A1- 4 to 3 times that of 4V alloy, but if it can be mass produced, the price will be Down. In addition to the use of an eyeglass frame, outside the golf club, it is also applicable to wide range of fields such as
Home Appliances precision coil springs, medical equipment, automobile parts and the like.
