Or, the body of the club head may be made of the ferrous metal and the ball hitting face of the club head may be a different material.

Description

1270395 发明, the invention description: [Technical field of the invention] The present invention relates to an iron rod, a wedge rod, a metal wood rod or a putter type golf club head, or an inlay portion for such a club head, including The ferrous metal 'more particularly contains ductile iron or grey cast iron. w [Prior Art] This application is based on U.S. Patent Application Serial No. 60/499,832, filed on Feb. 27, 2003, and U.S. Patent Application Serial No. 60/507, filed on Jan. No. 804, the entire disclosure of which is incorporated herein by reference. The conventional golf club head and the face inlay used in the golf club head are constructed of a variety of materials such as steel, non-ferrous metal alloys, titanium, aluminum, composites, plastics, rubber, and the like. Disadvantages associated with such golf club heads that are traditionally utilized in the art of golf club head manufacturing include: giving the golfer a "rough" during and after the golf club head hits a golf ball. Tactile sensation, poor durability, poor processability, poor wear resistance, use of high-density materials in special weight restrictions, and the lack of weight associated with the design of the club is the main model that is created in each step and There is a significant difference in size between the net remainder and a manufacturing cost of 13⁄4. Therefore, there is still a need for golf club materials and designs that reduce the above disadvantages and provide advantageous characteristics such as improved material shock absorption, workability, abrasion resistance, increased strength-to-weight ratio, phase 1270395 Reduction in other iron materials (4) Surface treatment and plating, a wide range of mechanical properties: malleability, acceptable table, reduced shrinkage and near net shape: manufacturing capacity, low material cost [invention] The invention is a gB + 丄, prior art golf club material designed to overcome the above prior. The invention is advantageously made of a Gol=density iron material or a prayer iron material. ; = by: There are special requirements for ductile iron or gray cast iron. The advantageous iron material may be a club head or may be present on the club head: the king's - inlaid portion of the ball striking surface, the same or different material as the club head. The remainder of the club head may be [Embodiment] The present invention relates to an iron club, a wedge rod, a metal wood pole or a putter type golf club head, or a club for the club head, including Iron-containing metals, more particularly ductile irQn or gray iron. Such metals may include high ductile iron, high-silic〇n iron, annealed ductile iron, austenitic ductile iron (austempered ductile). Iron) and grey cast iron. The ductile iron is a cast iron that has been treated to contain towns, strontium or rare earth metals (atomic number 5 7 - 7 1) during the casting step to cause substantially all of its graphite carbon with 1270395 (graphUic coffee (4) in prayer The main second-iron moment P car in (aS_CaSt C°ndltl〇n) takes the form of a pellet in iron-SlUC〇n(1). In the as-cast state, the graphite sphere is suspended in ferrite or Pearlite &amp; Heart (4) (4) Arrays with occasional carbides. The pearlite and carbide systems are transformed into almost ferrite microstructures using well-known annealing procedures by those skilled in the art of metallurgy.斩 ' ' ' 沾 与 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和 和Medium-strength alloy. Austenitic austempering ductile iron is a ductile iron that has been controlled by a conventional thermal step of 'causing a suspension containing primary acicular ferrite and high carbon austenite. Matrix microscopy of graphite spheres This microstructure provides improved strength over as-cast or annealed ductile iron, while at the same time providing a suitable "extension. ^ Gray cast iron - cast iron" is not treated with a graphite spheroidizer, substantially all of which Graphitic carbon forms a sheet in the as-cast state in the main bismuth-iron matrix. The flaky graphite structure of the A species in the iron matrix provides advantageous properties for many materials, including outstanding shock absorbing ability, excellent (four) abrasiveness and machinability. And a reduced density relative to other iron materials. The shock absorbing ability of gray mouth iron is 1.25 times greater than that of ordinary steel. The golf club head of the present invention preferably comprises a range of weight ratios below: The composition of the ductile iron · · 2 · 8 to 4 · 3 weight percent of carbon, 1270395 垔 percentage of 矽 1. 5 to 〇 to 1 weight percent of copper less than ο · 1 weight percent of magnesium, less than 〇.15 The weight percent of the phosphorus, and the balance of the majority of the iron.
