COMPOSITION FOR DISC BRAKE CALIPER HOUSING MANUFACTURING METHOD FOR DISC BRAKE CALIPER HOUSING USING THE SAME AND DISC BRAKE CALIPER HOUSING COMPRISING THE COMPOSITION

摘要

The present invention relates to a composition for a disc brake caliper housing, a method for manufacturing a disc brake caliper housing using the same, and a disc brake caliper housing including the composition, which can achieve excellent hardness and light weight, and can reduce manufacturing costs. According to the present invention, the method for manufacturing a caliper housing for a disc brake caliper is a method for manufacturing a caliper housing constituting a disc brake caliper, wherein, as an alloy composition for manufacturing the caliper housing constituting the disc brake caliper, provided is a composition for the disc brake caliper housing comprising silicon (Si), iron (Fe), manganese (Mn), magnesium (Mg), nickel (Ni) and aluminum (Al) in predetermined composition ratios, respectively. The method comprises the steps of: preparing, as a composition, an alloy composition for manufacturing a caliper housing comprising silicon (Si), iron (Fe), manganese (Mn), magnesium (Mg), nickel (Ni), and aluminum (Al); composing each of the prepared compositions at a predetermined composition ratio; melting the composition; injecting a molten alloy in a state of being heated at a predetermined temperature into a casting space of a casting mold in which a middle core is placed inside the casting space to form a shape corresponding to the caliper housing to be manufactured; and solidifying the molten alloy injected into the casting mold to complete a caliper housing.
