Early disc for pure iron, material selection and did not change much, but with advances in materials science, most modern motorcycleusing iron as a material for disc, now more common in stainless steel. Wide range of stainless steel, is excellent because of rigidcast iron stainless steel, you can reduce the thickness of plates,
integral braking system to reduce the weight. In addition, thedurability of stainless steel plate is also higher than that of cast iron plates.
In addition to stainless steel, dish surface is also a priority. In order to create sufficient hardness and toughess, complex heat treatment is required to ensure excellent mechanical properties, andunfortunately,
most metals heat treatment quality is unable todistinguish with the naked eye, even without expensive modification of the selling price on the heattreated plate endlessly.
