Features and Specifications

AMPCO® M4 is an exceptional aluminum bronze alloy known for its remarkable properties. This high performance material has mechanical properties that exceed those of conventional nickel aluminum bronzes. It features a unique composition with increased aluminum and iron content, resulting in a uniform distribution of the hard gamma 2 phase throughout the alloy. This results in excellent wear resistance, reduced friction, and improved sliding properties. As a result, it is well suited for applications requiring high mechanical strength at elevated temperatures, making it an ideal choice for aircraft landing gear bearings, bending dies, gear wheels, and more. Compliant with AMS 4590 for extrusions, this bronze alloy offers reliability and performance without the industrial hygiene requirements associated with beryllium copper alternatives.

Applications

AMPCO® M4 is used in a wide variety of industries due to its exceptional properties. This high performance aluminum bronze alloy excels in demanding environments. It is the first choice for aircraft landing gear bearings and bushings, ensuring reliable performance under extreme conditions. In the tube bending industry, aluminum bronze alloy is valued for its use in bending tools, including shoes and mandrels, due to its outstanding durability and wear resistance. It’s also a trusted material for gears and wear/guide plates, where its superior mechanical strength and corrosion resistance really shine. From aerospace to manufacturing to heavy equipment, AMPCO® M4 is proven in critical applications.
