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.

Tensile Strength Range Measured in KSI Varies with Temper and Form
	C62300	C62400	C62500	C63000	C64200
Min	75	90	100	90	75
Max	98	105	100	118	102

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.

Yield Strength Range Measured in KSI Varies with Temper and Form
	C62300	C62400	C62500	C63000	C64200
Min	35	40	55	50	35
Max	50	52	55	75	68

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.

Rockwell B Hardness Range Measured in KSI Varies With Temper and Form
	C62300	C62400	C62500	C63000	C64200
Min	80	87	29	96	77
Max	89	92	29	98	98

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.

For the sake of comparison, the table below shows the elongation range of five popular aluminum bronze alloys.

Elongation Range Measured As Percentage Varies With Temper and Form
	C62300	C62400	C62500	C63000	C64200
Min	22	14	1	15	22
Max	35	18	1	20	32
