Superelastic entropy alloy
EM-300
The superelastic entropy alloy EM-300 series is an innovative alloy with high elastic properties, featuring a yield strength greater than 600 MPa and a Young’s modulus less than 80 GPa. Applied to golf ball striking surfaces, tennis/badminton racket frames, and dental braces, the unique patented formula for high elasticity has a higher yield strength than β-type titanium alloy and a lower Young’s modulus than Ti-6Al-4V. It is a high-entropy alloy with both high strength and high elasticity.
Material Features
The superelastic entropy alloy EM-300 has high elastic properties, which can reach about two to three times that of titanium alloy. The steel ball bounce test video is shown below, showing that the elasticity of EM-300 is much better than that of 304 stainless steel and 6061 aluminum alloy:
Note: For the steel ball bounce test, the left side is fixed with a superelastic entropy alloy EM-300 round rod, the right side is fixed with 304 stainless steel and 6061 aluminum alloy round rods, and the acrylic tube is 40 cm long.
The superelastic entropy alloy EM-300 series can be used in golf ball striking surfaces, tennis/badminton racket frames and dental correction wires, etc.
