18k金是彩金吗?
8k金不一定是彩金,但彩金一定是18k金。18k金是指黄金含量为百分之75的合金,其余百分之25为别的贵金属,因此不像纯金那么软,比较硬,适合造型和镶嵌。18k金就是黄灿灿的金首饰,颜色较单一,款式也普通。
毕竟彩金并非纯金,但凡有点理智的人在购买之前都会想到彩金会不会掉色。很多朋友购买彩金不仅是因为其精细的做工,更是因为它所呈现的各种让人一见倾心的颜色。
彩金的介绍
其答案是否定的。真正的彩金按理论来说是不会掉色的,毕竟现代的工艺技术已经达到了某种高度。但是并不是说彩金不会掉色我们就可以不去保养爱护,彩金的不掉色源于佩戴者的小心呵护,不与含化学成分的物质相接触,拒绝长期的暴晒。
只要拥有着懂得保养,日常小心,方可保证彩金不在人为原因下掉色。如因污渍及灰尘的沾染而失去光泽,可于稀释温和的肥皂温水中软刷清洗及软布试干。
香水、清洁剂、漂白水、海水等都有可能导致金饰变色,因此在做清洁、游泳时,都应取下金饰,以免产生化学反应及被擦伤。避免把彩金首饰与其他首饰摆放在一起,特别是钻石,因其硬度会引致互相摩擦而刮花,故应以布盒子独立存放。
18k金到底是彩金吗?
18k金是彩金。
严格来说算,因为彩金就是因为颜色多的金属被称为彩金的,18K金就是75%的黄金和25%的其他金属合成的,可以有各种各样的颜色。比如14K金也可以被称为彩金,因为同样可以 *** 成多种颜色,所以不管是多少K,只要能合成不同颜色的就可以被称为彩金。
18k金与黄金区别
严格来说区别还是很大的,比较大区别的就是黄金含量了,因为18K金就是拥有75%的黄金和25%的其他金属合成的,所以虽然黄金比例高,但是已经不能算上纯金了。而黄金就是拥有99.6%以上的黄金含量能被称为黄金。
另外18K金和黄金的硬度也有不同,黄金的纯度越高其硬度就越软,而黄金的纯度可以达到99.6%以上,成年人用手就可以捏变形。而18K金首饰因为有了其他金属所以硬度会相对来说比较硬一点点,基本上普通人是捏不变形的。
18k金是不是就是彩金啊
18k金不一定就是彩金。
18k金是黄金含量至少达到75%的合金,即金含量为18/24的合金,其余25%为其它贵金属,包括铂,镍,银,钯金等。18K金是造价较低而且佩戴较舒适的一种金饰。
K金的计算方式是将纯黄金分为24份,24k金即足金,但在现实中不可能有100%的黄金,所以中国规定含量达到99.6%及以上的黄金就可以称为24K金。
