　　银银是一种古老的贵金属，是十八世纪及以前的怀表**多采用的材料，代表银的纯度，是银的**高纯度。银是一种活跃的金属，容易与空气中的硫起化学反应，出现黑色的氧化层，使银器变黑。如今在表应用中远不如金，原因就是它极易因水湿气等原因而失去光泽。以纯银的表带几乎没有，通常会在银的表面镀铑，加强硬度并保证不褪色。

　　金属表带材料大全金属表带有很多材质可以选择：

　　铂金是一种稀有且昂贵的天然纯白色金属，是**上**稀有的首饰用贵金属之一，每年的供应量仅为黄金的%，拥有几乎两倍于黄金的强度，比黄金稀有倍。铂金光泽洁白，自然纯净，纯净度高达%以上，浑然天成，经常佩带也不会褪色。表示纯度为%的铂金，表示纯度为%的铂金。通常只有非常高端的品牌才采用这种材料，而且是限量款。

　　金金是指黄金和其它金属混合在一起的合金，因其英文是，所以简称为金。贵金属部分，纯金为，但纯金太软不适合制作手表，必须混合其他金属以加强硬度，一般以银铜和钯为主，但不管混合何种金属，纯金的比例均占%(常说的金)。随着金银与铜的比例高低，可产生五种不同色泽的材质，分别以来表示含铜量的高低，如含铜量**高的红金以表示，而白金正确的说法是白色的金。

　　包金其表壳为不锈钢，外包一层金合金，经机械滚轧成为整体，其厚度以微米作为计量单位，微米等于毫米。**多厚达到微米，一般则只有到微米。电镀电镀是现代手表中常见的表壳装饰方法，电镀技术崛起于七十年代，因电镀均匀牢固，比包金成本低且不易脱落，又无锻黄壳变色锈蚀的可能，所以很快将两者淘汰出市场。现在电镀采用的技术都是离子电镀()

　　钛金属钛金属是一种比较昂贵的金属，在常被用在航天领域，其特点是非常轻坚硬耐腐蚀耐热和耐寒。钛金外观可以是光亮有光泽的金属，或是银灰色深灰色的粉末。目前很多**手表的款式都采用钛金属材料。除了以上提到的优点外，用于手表上还有个优点是钛金属不易使皮肤过敏(有些人对钢表带等材质过敏)

　　钨钛合金先以帕的压力将碳化钨和碳化钛粉末压进胚件里，然后压铸模，再在特制的熔炉内以摄氏度的高温将其烧结为密度极高的部件，**后经过多个工序并用钻石粉末打磨后就制成了闪闪生辉的钨钛合金，耐磨性能好。

　　钨钢硬度高，耐磨损，外观线条分明，光洁明亮，称为“耐磨损材质” 。可以和钢复合使用，做成表壳圈口或表带粒，增加壳带表面耐磨蚀性和装饰性。钨钢表在前几年非常流行，现在只有低端表在用此种材料了。陶瓷陶瓷光洁耐磨，不伤皮肤，主要成分是氧化锆，在一定温度条件下获得良好的加工性能，再通过**的加工方法，制作成精**表壳表带，也可通过特殊方法各种颜色，更显华丽高贵。

silver is one of the oldest precious metals, is before eighteenth Century and watch the most used materials on behalf of the purity of silver, silver is the highest purity. Silver is a kind of active metal, easy to react with sulfur in the air, appear black oxide layer, make silver black. Now in the table is not as far as gold, because it is very easy to lose luster due to moisture and other reasons. The silver watch strap almost no, usually rhodium plated on the surface of Ag, strengthen the hardness and ensure not to fade.

metal watchband Daquan metal watchband has a lot of material choice:

platinum is a rare and expensive natural pure white metal, is the world's rare jewelry with precious metals, the annual supply of only gold has%, almost two times the strength of gold, gold than rare times. Platinum gloss white, pure natural, high purity reached%, often wear will not fade like nature itself. To show the purity of% of the platinum, expressed as% of the purity of platinum. Usually only very high-end brands to use this material, but also a limited edition.

Jin Jin is an alloy of gold and other metals mixed together, because it is in English, so it is called gold. Precious metals, gold, but gold is not suitable for the production of watches, must be mixed with other metals to enhance hardness, with silver copper and palladium in general, but no matter what kind of mixed metal, gold proportion% (say Kim). With gold and silver and copper ratio, can produce five different color materials, respectively, since the said copper content level, such as the highest amount of copper containing gold and platinum to indicate, the correct term is white gold.

gold case is made of stainless steel, outsourcing a layer of gold alloy by mechanical rolling as a whole, the thickness in micrometers as the unit of measurement, micron is mm. Up to a maximum of microns, generally only to microns. Electroplating is a common method of modern watches watchcase decoration, electroplating technology rise in 70s, because of electroplating uniform solid, low cost than gold and not easy to fall off, and no discoloration corrosion may be forged yellow shell, it will soon two out of the market. Now plating technology used are ion plating ()

titanium metal titanium is a relatively expensive metal, is often used in the aerospace field, which is characterized by very light and hard corrosion resistance heat and cold. Titanium appearance can be bright shiny metal, silver or dark grey powder. At present, a lot of high-end watches are using titanium materials. In addition to the advantages mentioned above, there is a watch for the advantages of titanium metal is not easy to make the skin allergy (some of the material such as steel watchband allergy)

tungsten titanium alloy with PA pressure tungsten carbide and titanium carbide powder is pressed into the blank, and then die, then in a special furnace with high temperature Celsius the sintering for high density components, finally through multiple processes and after grinding with diamond powder made of tungsten titanium alloy shining Sheng Hui, good wear resistance.

steel has high hardness, abrasion resistance, appearance is sharp, bright and clean, called "wear-resistant material". You can use steel and composite case, made of ring or watchband grain, increase shell with surface corrosion resistance and decorative. Tungsten steel sheet is very popular in a few years ago, now only in the low-end table with this material. Ceramic wear-resistant finish, not to hurt the skin, is the main component of zirconia, obtain good processing performance under certain temperature conditions, then through advanced processing method, make watchcase watchband beautifully, but also through a special method of various colors, more gorgeous and noble.
