High-tenacity cast titanium alloy material for golf club head

The invention discloses a high-tenacity cast titanium alloy material for a golf club head. The high-tenacity cast titanium alloy material for the golf club head comprises, by mass, 5.3%-6.5% of Al, 1.65%-2.45% of Sn, 2.3%-3.2% of Mo, 1.8%-2.2% of Nb, 1.7%-2.4% of Zr, 0.95%-1.95% of Cr, 0.55%-0.85% of Ni, 0.08%-0.14% of Fe, 0.003%-0.007% of C, 0.01%-0.04% of N, 0.008%-0.014% of H, 0.09%-0.14% of O and the balance Ti. In this way, according to the golf club head made of the cast titanium alloy material prepared through the formula, the indoor-temperature yield strength is 1100 MPa or over, the tensile strength is 1200 MPa or over, the ductility is 8% or over, the percentage reduction of area is 15% or over, and meanwhile the golf club head has the advantages of being high in strength, tenacity and damage tolerance and the like; the usability of a product is more excellent, the service life of the product can be prolonged easily, and the weldability is good; and in addition, the casting yield is high, and convenience is brought for production and manufacturing.
