Precious metals in jewelry manufacturing and their best use
There are many articles on the precious metals on the web and some of them are professionals quiet, with many details and data. I will not try to give more. Here, I offer a simple version and avoiding jargon wide add my professional opinion on the best use of these metals in order to use its unique properties. This article focuses on the most popular precious metals for jewelry: gold, platinum, and the rapid growth in popularity of palladium. Pure gold and platinum are soft metals that are extremely dense. Pure gold is about two and a half times heavier than iron and pure platinum is slightly less than three. Although very beautiful color pure metals are not suitable for fine jewelry for its sweetness. soft metals are easily damaged, difficult to polish, not suitable for detailed work. This is why mixed (alloy) with other metals to give the desired properties.
It is also the place where it all carats and confusing numbers involved. In fact, it is fairly simple. All metals in nature are pure white or gray, but two bright yellow gold – copper and red-pink. Now we turn to precious metals. All different colors of precious metals are obtained by mixing the metal with the color white.
Carat is a confusing name of the purity or the law of precious metals. It is confusing because the same word is used as a measure of weight for gemstones. It carat is equal to 0. 2gr. and have nothing to do with the fineness of metal. carat to differentiate from each other in certain standards, carat is marked by CT and the purity or karat kt k. We can accept this rule to avoid confusion in other articles, so when we go the purity of the metal we use “carat”. Karat is used mainly to define the purity of gold alloys. Different countries have different standards for the purity of gold alloys used in the world are 9kt or 375, or 416 10kt, 14kt or 585, or 750 18kt, 21kt, 22 or 875 and 916. The number of alternatives that can only be used as a label indicates the number of pieces of gold in the alloy 1000. The easy way to translate this information into a manageable is perceived as the percentage of pure gold used x10. For example 750 means 75% of the content of pure gold or 18 kt.
Platinum is used in a form almost 95% pure and alloy 950 is punched in the series. All alloys contain 95 pure platinum. 0% or more may also be marked with the word “full of platinum” or “platforms. “On the other alloys used are 900 (90%), 800 (80%) and 585 (58. 5) also called carat platinum. The amazing incredible qualities of this metal are best described in another article in which I compare with Alternative white gold.
The 950 palladium alloys are as white as platinum, that blends well with white diamonds and eliminate the need for rhodium. Palladium is a light metal with a weight close to money and a lot lighter than platinum and alloys of high-karat, is the metal of choice for items such as large earrings. At the time of writing, the price of 950 palladium alloys is about one third the price of 18 carat white gold with a high potential for large solid pieces greatly reduced price. The disadvantage is that the materials while the quality of the casting of palladium and equipment requested is not currently viable for workshops characteristics usually jewelry precious metals are the following: 1). carats or fineness mark (for example, or 18kt/ct 750) 2) carat mark, is of little value without the seal manufacturers since the declaration of purity is not signed. Be careful, in most countries, buy a karat stamp a few dollars.
The variety of gold and mechanical properties is achieved by alloying the gold with one or more metals. Gold white for example, is an alloy of gold to launder the metal, usually palladium, nickel or silver, or combinations of them. Because pure gold is always yellow, the alloy is the (basic) metals that gives its color and carat properties. For example, in order to eradicate an article as it should be 18K content of at least 75% of fine gold. The remaining 25 percent of the metal alloy to determine its color and physical properties. 8 Yes. 4% copper and 16 6.% silver alloy is used, we will end with the traditional 18 carat gold rich. If mixing the same quantity of gold with palladium 15% and 10% have gold, silver, good quality white. Content constant 18K gold alloy is always 75% pure gold. higher than alloys 18k white gold are not possible because the metal alloy are not sufficient to absorb the yellow gold. 21k or 22k gold is always yellow, very yellow. The same thing applies for platinum and palladium, although these metals are used in a much more pure (95% is the norm) and no detectable change in color. The only changes that exist in physical properties.
< br /> Now, with our newly acquired knowledge of precious metals are susceptible to the following questions: What are the best alloys? What metal jewelry should I buy? />
dissimilar metals are in good different purposes. In general (and if you can afford) to buy the alloys with high precious metal content. It’s mainly for gold, platinum and palladium are used in an almost pure form. or 18 carat or more distinctive real gold and precious metals properties. My opinion is that gold alloys containing less than 50% (less than 14k) should not be called gold, bronze gold or something else sets the lower gold content. If you’re looking for heavy and bulky is better to go silver with bold details in gold, or precium very new (25 % palladium and silver alloys developed by Handy & Hartman), who may already be on the market at the time you read this article. For fine jewelry pieces to choose from 18 carat gold and platinum. 18k white gold can be used for heavier, thicker pieces while platinum is the best for fine adjustments with many details. It makes no sense to allocate $ 10,000 of diamonds in white gold, saving 300-400 $ difference in platinum setting. In addition to the aesthetic superiority, the security environment of platinum is immensely greater. When we hit the slopes, especially large, the choice of alloys is essential. Palladium the first choice followed by 14k white. for yellow, stick to 18k. You can never get the right color at the bottom carats. Then, the capacity of its gold to light work at hand. Try to find the craftsman right. It really made the difference. Parameters weight of wooden poles is low, even for large diamond, so the choice of platinum targets. the difference is negligible prices, but the difference in the strength and safety and quality – wide. Another advantage of platinum bolts – could be very delicate and retain their strength.
