球铁铸件差不多已在所有主要工业部门中得到应用，这些部门要求高的强度、塑性、韧性、耐磨性、耐严 重的热和机械冲击、耐高温或低温、耐腐蚀以及尺寸稳定性等。为了满足使用条件的这些变化、球墨铸铁现有许多牌号，提供了机械性能和物理性能的一个很宽的范围。
如国际标准化组织ISO1083所规定的大多数球墨铸铁铸件，主要是以非合金态生产的。显然，这个范围包括抗拉强度大于800牛顿/毫米，延伸率为2%的高强度牌号。另一个极端是高塑性牌号，其延伸率大于17%，而相应的强度较低(最低为370牛顿/毫米)。强度和延伸率并不是设计者选择材料的唯一根，而其它决定性的重要性能还包括屈服强度、弹性模数、耐磨性和疲劳强度、硬度和冲击性能。另外，耐蚀性和抗氧化以及电磁性能对于设计者也许是关键的。为了满足这些特殊使用，研制了一组奥氏体球铁，通常叫傲Ni一Resis亡球铁。这些奥氏体球铁，主要用锌、铬和锰合金化，并且列入国际标准。

They said the artificial sweeteners in diet drinks are not healthy. Dr Guy Mintz, a heart specialist, said, "The belief that artificial sweeteners are a safe substitute for sugar is fake news."

He added, "Artificial sweeteners have been associated with weight gain, insulin resistance, and diabetes."
The research is published in the Journal of the American College of Cardiology. Researchers looked at health data from over 100,000 people in France.
