Golf club head

A golf club head that, when oriented in a reference position, comprises:

• a striking face having a face center and defining a face plane;
• a vertical center plane perpendicular to the face plane and passing through the face center;
• a sole portion;
• a top portion;
• a heel portion;
• a toe portion opposite the heel portion;
• a hosel configured to receive a shaft and defining a hosel axis;
• a club head mass between about 250 g and 320 g;
• a loft, L, no less than 39°;
• a club head center of gravity spaced rearward from the face plane by a distance, D5, D5 being no greater than 2.2 mm, and spaced from the vertical center plane by a distance, D7, D7 being no greater than 5 mm;
• a moment of inertia, Iyy, measured about an axis extending in the heel to toe direction and passing through the center of gravity, Iyy being no less than 1000 g*cm2;
• and
• a first component comprising a first material having a first melting point and a first density and a second component comprising a second material having a second melting point higher than the first melting point and a second density less than the first density, the second component at least partially encapsulated by the first component,
• wherein a ratio of Iyy/Izz is no less than 0.25, Izz being a moment of inertia measured about a virtual vertical axis passing through the center of gravity.
