Brake disk composed from different metals and method for manufacturing the same

摘要

The invention provides techniques capable of forming a light brake disk and of suppressing the cost of the brake disk A brake disk (30) has a disk body (35) formed of a titanium alloy, and inner and outer friction members (40, 42) formed of a stainless steel and bonded to the opposite surfaces (36a, 36b) of the disk body (35) by a brazing method. The friction members (40, 42) can be simply bonded to the opposite surfaces (36a, 36b) of the disk body (35). <IMAGE>
