    • A putter golf club head includes a body fitted with relatively high-density heel and toe inserts. A golf putter club head includes a body formed of a first material (e.g., titanium) having a density of approximately 3.0 g/cm3 to 7.0 g/cm3. Two cavities are formed in the body, one adjacent to the heel region of the body, and another adjacent to the toe region. Inserts are provided in each of the two cavities and are formed of a second material (e.g., tungsten) having a density ranging from approximately 15.0 g/cm3 to 20.0 g/cm3. The cavities may be configured such that they extend to (or are bounded by) the bottom surface and/or the front face of the body. In one embodiment, the body of the putter club head has an elastic modulus greater than approximately 90 GPa while the density of the insert material is greater than the density of the body material by a factor of at least 3.0.
    • 推杆高尔夫球杆头包括装配有相对高密度跟部和脚趾刀片的主体。 一种高尔夫球棍球杆头包括由密度约为3.0g / cm 3至7.0g / cm 3的第一材料(例如钛)形成的主体。 在身体中形成两个腔体,一个邻近身体跟部区域,另一个邻近脚趾区域。 插入件设置在两个空腔的每一个中,并且由密度范围为约15.0g / cm 3至20.0g / cm 3的第二材料(例如钨)形成, SUP>。 空腔可以被配置为使得它们延伸到(或由其限定)底部表面和/或身体的前表面。 在一个实施例中,推杆球杆头的主体具有大于约90GPa的弹性模量,而插入材料的密度大于体材料的密度至少为3.0。
