C63000 alloy, commonly referred to as aluminum bronze is frequently used in making aircraft parts, balls, bearings, cams, gears, heat exchanger parts, plunger tips, pump parts, shafting, structural members, tanks, valve components, bolts, nuts, ship propellers, and faucets.

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 C63000 ranges from 90 to 118 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 al 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.

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.
