High thermal conductivity disk brakes

A disc brake rotor, comprising:

• (a) mounting hat;
• and
• (b) solid disc, rigidly affixed to said mounting hat, and including:
• i. a transverse dimension core, made of a first metal;
• ii. two rubbing-surface claddings, set on either transverse side of said core, said claddings made of a second metal and having a thickness of 1-10 mm, and further defining physical engagement features;
• iii. a third metal interposed between said first metal and said second metal;
• and
• iv. wherein said second metal bonded with said first metal metallurgically through said third metal and mechanically by said engagement features.

A method of fabricating a disk for a disk brake system, comprising:

• (a) forming a cladding workpiece having a first major external surface defining engagement features;
• (b) coating said first major external surface with a second metal;
• (c) providing a mold, defining an interior shape of a rotor;
• (d) inserting said cladding workpiece into said mold;
• (e) providing a molten third metal;
• and
• (f) pouring said molten third metal into said mold so that it engages to said engagement features and reacts with said second metal and permitting said molten third metal to cool, thereby forming a disk made of said third metal, which is metallurgically bonded and mechanically interlocked to said cladding workpiece.
