Notice: The weights listed are the best estimates of the actual weights we will ship. They are a combination of the calculated theoretical weights and an average of actual weights. Our weights are conservative to the heavier side but there may be slight variations in weight from bar to bar.
The Physical, Fabrication and Thermal Properties shown here represent reasonable approximations suitable for general engineering use. Due to commercial variations in compositions and to manufacturing limitations, they should not be used for specification purposes.
