Standard ISO codes define grain sizes from fine to medium and do not represent the today’s state of the art in cemented carbides. The selection of the optimum carbide grade should therefore always be done based on application data of the customer.
标准 ISO 代码定义粒度由细至中等，并没有反应最先进的硬质合金发展成果。最佳的硬质合金牌号的选择应因此始终基于客户的实际应用的数据。
