Golf club head alloy and preparation method thereof

Abstract

The invention provides a golf club head alloy and a preparation method thereof and belongs to the technical field of alloys. The golf club head alloy is prepared from the following components in percentage by weight: 0.25 percent to 1.0 percent of silicon, 0.25 percent to 1.5 percent of manganese, 2.0 percent to 3.5 percent of molybdenum, 6.0 percent to 8.0 percent of nickel, 15.5 percent to 18.0percent of tungsten, 0.15 percent to 0.65 percent of aluminum, 0.1 percent to 0.8 percent of titanium and the balance of iron and unavoidable impurities. According to the golf club head alloy and thepreparation method thereof, the nickel is added so that the high-temperature strength and the anti-impact toughness of the alloy material can be improved and the specific gravity of the tungsten is great so that the alloy material has very high rigidity and wear resistance and the heat strength can be improved; the silicon has the effect of improving the flowability when the alloy is liquid and the molybdenum and the titanium are matched so that the mechanical property of the alloy is improved; the aluminum is added to stabilize the ductility of the alloy so that a condition that the ductilityof the alloy is greatly reduced when the strength is improved is avoided; meanwhile, the golf club head alloy and the preparation method thereof have the advantages of simple production technology and high efficiency; a golf club head with the strength, rigidity and abrasion resistance, which are more excellent than that of a golf club head made of an existing alloy, is manufactured.

Description

technical field [0001] The invention relates to a golf club head alloy and a preparation method thereof, belonging to the technical field of alloys. Background technique [0002] Golf is considered to be a sport that is most affected by materials, and the most direct and simplest is the material requirements of golf club heads. Generally, the hitting distance is mainly affected by the hardness and tensile strength of the hitting surface of the golf head. Only when these two properties are high can it be ensured that more swinging force is transmitted to the ball, so that the ball is Hit farther and fly more ideally. With the birth and development of golf, club head materials have changed from wood to mild steel. At present, most golf club head materials are titanium alloy materials, which have high specific strength and light weight, and can be made into large-sized ball heads. The larger the volume, the larger the moment of inertia, and the less curvature of the ball path...

AI Technical Summary

Problems solved by technology

However, the process performance of titanium alloy is poor, the hardness can only reach about HRC46, and the cutting process is difficult. In thermal processing, it is very easy to absorb impurities such as hydrogen, oxygen, nitrogen, carbon, etc., and has poor wear resistance, and the production process is complicated.
