<p>When buying a watch, we always struggle to buy a steel strap or a leather strap? In fact, this is just a general term. There are many types of <a href="https://www.jinhuashengwatch.com/product" rel="noopener noreferrer" target="_blank">metal watch</a> bands. Different from personal identity, wearing environment, and service life, the type of choice may be different.</p><p><br></p><p>Let me analyze the difference between some metal strap materials:</p><p><br></p><p>1Platinum strap: Generally divided into Pt900 and Pt9500, the number behind it indicates purity. For example, Pt900 is 90% platinum jewelry. Platinum has the advantages of white gloss, natural purity, and purity of over 90%. It is natural and will not fade when worn frequently. It is the first choice. The disadvantage is that the word "expensive" is 30 times rarer than gold.</p><p><br></p><p>2 K gold strap: Why is there no gold strap? Because gold is too soft and easily deformed. So we use gold and other metals mixed together called K gold. Generally, silver, copper and palladium are mainly used, but no matter what kind of metal is mixed, the proportion of pure gold is 75%. With the ratio of gold, silver and copper, five different color materials can be produced. N is used to represent the copper content. For example, red gold with the highest copper content is represented by 5N, while white gold is correct to say white K gold. The advantage is that the color is good-looking, as for the disadvantages, it is still more "expensive" but the price is very high.</p><p><br></p><p>3 gold-clad: Its case is made of stainless steel, wrapped with a layer of gold alloy, and mechanically rolled into a whole. Its thickness is measured in microns, and 1 micron is equal to 1/1000 mm. The maximum thickness is 10 to 15 microns, and generally only 2 to 3 microns. This kind of watch strap is currently more common and has a high cost performance.</p><p><br></p><p>4 Electroplating: Electroplating is a common method of decorating the case of modern watches. Electroplating technology emerged in the 1970s. Because electroplating is uniform and firm, it is less expensive than gold coating and not easy to fall off, and there is no possibility of discoloration or corrosion of the forged yellow case. Both will soon be eliminated from the market.</p>
