[0050] Grinding: the blank of the golf strike pad 10 is ground to remove the burr of the blank of the golf strike pad 10 and provide a golf strike pad 10 that has a light weight, a high hardness and a low cost. Similarly, a glass fiber layer 11 is securely adhered to a back of the golf strike pad 10.

[0051] With reference to FIG. 8 that shows a fourth preferred embodiment of the manufacturing method of golf strike pad in accordance with the present invention, in this embodiment, the manufacturing method comprises the following steps.

[0052] Hot melt: the aluminum-magnesium alloy is heated and melted.

[0053] Mixing: the powders of the silicon carbide and the sodium silicate are evenly mixed according to the ratio disclosed in the first preferred embodiment and added into the hot melted aluminum-magnesium alloy.

[0054] Casting: the hot melted aluminum-magnesium alloy, containing the powders of the silicon carbide and the sodium silicate, is casted into a mold.

[0056] Grinding: the blank of the golf strike pad 10 is ground to remove the burr of the blank of the golf strike pad 10 and provide a golf strike pad 10 that has a light weight, a high hardness and a low cost. Similarly, a glass fiber layer 11 is securely adhered to a back of the golf strike pad 10.

[0057] Furthermore, the golf strike pad 10 in accordance with the present invention also can be manufactured by powder metallurgy or die-casting. The powders of the silicon carbide and the sodium silicate are used to ?increase the contract area among the powders of the silicon carbide and the sodium silicate, and the aluminum-magnesium alloy. The diameter of the powders of the silicon carbide and the sodium silicate is more smaller, the bonding strength among the powders of the silicon carbide and the sodium silicate, and the aluminum-magnesium alloy is more stronger.

[0058] The aluminum-magnesium alloy containing the silicon carbide and the sodium silicate has an excellent heat dissipation effect such that it is usually provided for high-level radiator that is the reason why the golf strike pad 10 in accordance with the present invention is made of aluminum-magnesium alloy that contains the silicon carbide and the sodium silicate. The golf strike pad is inwardly deformed and immediately causes high heat energy. The golf strike pad 10 made of aluminum-magnesium alloy containing the silicon carbide and the sodium silicate can quickly release the high heat energy during striking the golf ball and reduce the metal fatigue level for extending the use life of the golf strike pad 10.

[0059] Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
