Combines high strength with fair machinability and hot forgability.
Full alloy description:
A. W. Fraser Alloy 686 is a leaded manganese bronze combining high strength and excellent hot forging and corrosion resistant properties.
Used extensively for marine applications propeller shafts, valve bodies, spindles, nuts, bolts, gears and bearings. This alloy has good machinability due to the addition of lead.
The composition of A.W. Fraser alloy 686 is strictly controlled as are the extrusion and finishing operations to achieve a constant standard of quality, properties and structure.
All extrusions are manufactured from continuous cast billet stock ensuring uniform dispersion of lead particles and freedom from porosity.
Machinability Rating: 70
SAE Grade: n/a
