For low density titanium alloys containing aluminum and alum with high strength and casting flow performance, pure aluminum (Al) and aluminum-alum (Al-V) intermediate alloys are added into the sponge titanium (Ti) matrix with a weight percentage of 86.0 ~ 90.0. Weigh 3.32 ~ 7.16 pure aluminum and 5.64 ~ 8.18 aluminum-alum intermediate alloy with V content of 55% into 86.0 ~ 90.0 titanium sponge and stir evenly to form Ti-Al-V mixture, then press Ti-Al-V mixture into titanium sponge electrode. Then the sponge titanium electrode was placed in the vacuum consumable electrode arc furnace or vacuum induction furnace for vacuum melting to obtain low density titanium alloy with high strength and casting flow properties, containing Al6.85 ~ 9.5%, containing alum 3.1 ~ 4.5% and containing titanium 86.0 ~ 90.0%. The finished product rate of pouring golf club head reached 98% and was suitable for the preparation of bearing parts.
Low density titanium alloy has a huge market potential, such as the golf club head made of low density titanium alloy can reduce the weight of the current titanium club head and increase the volume of the club head, in order to improve the flight distance of the golf ball and the accuracy of the shot.
Low density titanium alloy is a lightweight material that is particularly suitable for making golf club heads to reduce the weight of golf club heads. Under the premise of reducing the weight of the golf club head, the volume or thickness of the club head can be increased, thus increasing the strength and rigidity of the club head and improving the accuracy of the golfer when hitting the ball. To increase the strength of the cue head is to increase the strength of low-density titanium alloy, which includes yield strength, tensile strength and hardness. The low density titanium alloy for the manufacture of golf club heads has been developed in this institute for many years.
