Cast bronze alloys are listed chronologically by their nominal dimensions. Any continuously cast bronze tube is guaranteed “to finish to” its nominal size. To accomplish this, “clean-up” material is added to both the ID (inside diameter) and OD (outside diameter).
Read MoreWhen speaking of cast bronze products, there are numerous methods of casting currently in use. These are sand casting, centrifugal casting, and continuous casting. This post will look at continuous casting and outline the benefits of this process.
The superior qualities of continuous casting are achieved by feeding molten metal through a furnace to an inert cast protected
