X = X-ray

X-ray crystallography is a fundamental tool for examining the structure of materials including, especially, metals and alloys. All Bantam boxes are cast with a test nodule included in the mould; these nodules are then subjected to metallurgical testing to prove the structure of the spheroidal graphite grade of cast iron.
