1. A method for joining multiple iron-type golf club head components, the method comprising:
positioning a first attachment surface of an iron-type body composed of a steel material to a second attachment surface of a single material face component consisting of a titanium alloy material, wherein a first brazing material is applied to the first attachment surface, wherein the first brazing material is a copper alloy based brazing material consisting of copper, manganese and nickel, the iron-type body having an internal edge defining a recess, the first attachment surface formed continuously around an entire perimeter portion of the body, wherein the face component is disposed over the recess;
positioning a third attachment surface of a weight component to a fourth attachment surface of the iron-type body, wherein the weight component is composed of a tungsten material, wherein a second brazing material is applied to the third attachment surface, wherein the second brazing material is a BNi-2 nickel-based brazing material; and
performing a single brazing cycle within a vacuum brazing furnace to braze the face component to the iron-type body and the weight component to the iron-type body;
wherein a miter joint is formed between the second attachment surface of the face component and the first attachment surface of the body and has an angle ranging from 10 degrees to 80 degrees relative to a plane of a rear surface of the face component, wherein the second attachment surface of the face component is formed continuously around an entire circumference of the rear surface of the face component, and wherein the second attachment surface of the face component has a width ranging from 0.04 inch to 0.5 inch and wherein the first attachment surface of the body has a width substantially matching the width of the second attachment surface of the face component.
