Why Use Tungsten Alloy for Golf Screw? Numerous techniques have been used for weighting golf club heads in order to gain better performance. In persimmon wood club heads, weights were attached to the sole in order to lower the center of gravity. The first metal woods had sufficient weight, however, the weight distribution deterred slightly from performance. The refinement of hollow metal woods with weighting on the sole improved upon the performance of these clubs. We use a tungsten screw in the sole of each titanium club head body to vary the weight of the golf club head.
We can offer golf club head with a sole component entirely composed of a tungsten alloy material. We adopt the method of Metal Injection Molding, making an entire golf club head composed of a metal injection molded material having a tungsten alloy composition.
Advantages of tungsten alloy golf head weight part by MIM method 1,High strength,Well-toughness,Hardness of fit,Excellent machinability
2,Density-Designed according to customers needs (10~18.6g/cc)
3,Dense material without holes
4,Not rust
5,Color consistency
