Bronzes are unquestionably the most versatile class of bearing materials, offering a broad range of properties from a wide selection of alloys and compositions.

The high thermal conductivity of copper alloys makes them ideal materials for the injection mold sprue bushing and runner bars.

In North America two injection mold nozzle and sprue bushing radii are used, 1/2 and 3/4 inch. To insure proper fit up, the nozzle radius is nominal -.015 inch, while the sprue radius is nominal +. 015 inch, required tolerances to use.
