metal-to-metal

Alloy against alloy contact

Metal-to-metal describes direct contact between two metal surfaces without cushioning, lubrication, or intervening material.

In engineering, metal-to-metal seals rely on precision-machined surfaces pressed together.

The phrase often signals a problem: The brakes are grinding metal-to-metal means the pads have worn through completely.
