| titleOfInvention | Material for golf club head with low iron density |
| abstract | A material for golf club head with a low iron density has an increased strength through its working process (cold forging or hot forging) and is suitable for being used as the striking face of a wooden golf club head. The invented material includes 25 to 31% of Mn, 7 to 10% of Al, and 0.9 to 1.1% of C, and optionally 0.8 to 1.5% of Si or 5 to 7% of Cr, the balance being iron. The addition of Cr and Si enables the material to have an excellent atmospheric corrosion resistance. The material can have a micro structure with a variously proportioned precipitation phase after a cast being chilled or plasticized, after by a thermal treatment at 950 to 1270 DEG C for 1 to 24 hours. Its alloidal density can be lower than 6.6g/cm3, or even 6.1 to 6.6g/cm3, and have excellent surface properties after receiving hot forging at 800 to 1050 DEG C. Products with excellent tensile strength, ductility, low density, high strength and high corrosion resistance can be achieved after receiving thermal treatments at 980 to 1080 DEG C for 1 to 4 hours and 500 to 650 DEG C for 4 to 8 hours, and cold rolling for altering their grain structures, and suitable timely treatments. |
