C62400 alloy, commonly referred to as aluminum bronze, 11% is frequently used in making automotive valve guides, bolts, nuts, cams, gears, valve components, and marine hardware.

The properties of any alloy will vary with the size, shape and temper of the sample being tested. But the industry-standard information below should serve as a helpful guideline.

Tensile Strength

The tensile strength of a material is a measure of the amount of stress it can withstand while being pulled before it will break. Aluminum Bronze is especially valued for its superior tensile strength. For example, C31400, a non-aluminum bronze, has a tensile strength that ranges from 37 to 60 ksi depending on its temper and form. By comparison, the tensile strength of C62400 ranges from 75 to 102 ksi.

For the sake of comparison, the table below shows the tensile strength of five popular aluminum bronze alloys.

Yield Strength

The yield strength of an alloy is defined as the point at which it begins to deform. It’s an indication of the limit of the alloy’s elastic behavior. Stretch it and it changes shape. Remove the stress and it returns to its original shape. At some point, it breaks.

For the sake of comparison, the table below shows the yield strength of five popular aluminum bronze alloys.

Hardness

One of the major benefits of aluminum bronze as an alloy is its hardness which is one of the reasons it is selected for demanding applications.

For the sake of comparison, the table below shows the Rockwell B Hardness  of five popular aluminum bronze alloys.

Elongation

The elongation properties of an alloy determine how much bending and shaping it can withstand before it breaks. It’s usually inversely proportional to hardness.
