Tungsten Alloy Golf Head Counterweight
A golf head comprises a golf head body and the bottom of which is provided with a welding port and a dual-gravity tungsten alloy counterweight plate body which is welded to the welding port.
The dual-gravity counterweight plate body comprises a tungsten alloy counterweight and a metal part which is arranged at the periphery of the tungsten alloy counterweight and is made from the same metal material as the golf head body. The dual-gravity counterweight plate body is welded to the welding port of the golf head body, and the welding port is ground to form the golf head, the bottom of which is provide with the tungsten alloy part. The gravity and weight are averagely distributed on the area of the bottom of the golf head under the condition that the thickness of the golf head is not changed, so the effect of lower center of gravity and better counterweight can be achieved, thus greatly improving stability and solidity of playing the golf.
Tungsten alloy counterweight with high density is popular used for golf headnowadays.Table above clearly shows you typical properties of tungsten alloy golf head parts .
