Leaded tin bronze with excellent machinability, medium strength and good corrosion resistance. Will withstand mild acids as found in mine water.
Full alloy description:
A.W. Fraser Alloy 370 is a free machining brass conforming to the requirements of UNS C37000.
The lower lead content of this alloy makes it suitable for forging applications as well as machining operations.
The composition of A.W. Fraser alloy 370 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.
Alloy 370 is susceptible to dezincification under certain conditions and is classified a category III alloy.
Machinability Rating: 95
SAE Grade: 64
