根据材料，回答下面的题目。金是一种具有美丽光泽的贵金属，是人类最早应用的金属之一。金最大的特点是不易氧化，即使在千度高温下也不变色，因此获了“真金不怕火炼”的美誉。在世界上，绝对的纯金是没有的，一般工业用金也不过为99．99%左右。可见“金无足赤”不无科学道理。通常人们所说的纯金(也有称之为赤金、足金的)，纯度约在99%。由于纯金的硬度低、塑性好，用它制成的首饰不耐磨，易变形，所以近代很少用纯度很高的金来制作首饰，而是将它配制成K金后再使用。K金是金与其他金属熔合而形成的金基合金。常用于首饰生产的有金铜合金和金银合金。金铜合金微呈紫红；金银合金则略显淡黄；为此，K金首饰在成品之前一般均进行镀金处理。另外，若在金中加入其他金属元素，还可以制成青色、蓝色和红色等各种颜色的K金饰品。K金按其成色高低分为24K，即24成。24K金为纯金，成色最高。l8K金，则说明该合金中含金18成，其他金属占6成。K金首饰的含金量百分比为：8K——33．3%；9K——37．55%；10K——41．7%；l2K——50%；l4K——58．5%；l8K——75%；20K——83．4%；22K——91．67%。目前，在国外(in overseas)K金首饰很流行。英国盛行9K金，美国和西欧则喜欢l4K金，香港最喜欢(the most interesting)l8K金首饰。纯金的比重为l9．3，是钢铁的2．5倍。一寸见方的金块约重700克左右，即超过一市斤。下列对纯金的表述，不符合文意的一项是 （ ）
