Gold<\/a> without additives is rarely found in nature, most often it is an impurity. When the metal is refined, it is purified. But it cannot be used for jewelry, radio parts, etc. The material is soft and easily deformed. The material is soft and easily deformed. But it also has its own specific application. It is necessary to find out what the metal can be used for, to this end determine its purity degree.<\/p>\n\n\n\n

There are two systems in use right now: Carat<\/a> and metric. To learn how to navigate them, you can start with the highest metal: 24 carat of gold<\/a> - is how much, you can find out by performing simple calculations. It is distinguished by a set of specific properties and high cost.<\/p>\n\n\n\n

What is 24 carat gold - the concept and origin of the word carat<\/h2>\n\n\n\n

The purity of a piece can be different: defined by carats, also denoted by the assay (taking into account the amount of gold per 1,000 particles). Russia and many post-Soviet and Western countries use the metric system. It implies that the metal must be assayed after determining the amount of additives. <\/p>\n\n\n\n

\n

The US, Canada, the UAE, China and some Western European countries use the carat system. The corresponding stigma on the precious metal is still found in Great Britain as well, although the metric system was introduced some time ago.<\/p>\n<\/blockquote>\n\n\n\n

However, both methods of determining the degree of purity gold<\/a> provide the same result. But the designation is different. The carat system requires a ratio of pure precious metal to impurities contained in 24 parts of the alloy. One such fraction is equivalent to 200 mg of gold.<\/p>\n\n\n\n

The designation carat is ct, and this Au-based unit of material purity comes from the Italian word \"carato\" - the pod of the carob tree. But the weight unit of the alloy corresponds more to its seed, the mass of which is 200 mg. This answers the question: 1 carat gold, how many grams.<\/p>\n\n\n\n

Regardless of which method of determining the purity of the metal was used, it is possible to convert the resulting value into another system. A summary table has been created for this purpose. World systems:<\/p>\n\n\n\n

Translation of the sample into carats and back<\/h2>\n\n\n\n

24-carat gold is considered pure gold. This means that such a precious metal does not need additional calculations. Other values are taken as reference units in calculations, thanks to which pure gold can be represented for each of the systems. Universal formula:<\/p>\n\n\n\n

\n

24 : 100 = X : Y,<\/strong><\/p>\n<\/blockquote>\n\n\n\n

where X - carat sample<\/strong><\/p>\n\n\n\n

Y-metric.<\/strong><\/p>\n\n\n\n

The amount of pure gold can be found out by performing simple steps. If you need to convert a metric sample to carat, use a variant of the above formula:<\/p>\n\n\n\n

\"Gold<\/span>

\n

X = 24 * 585 : 1000 = 14K.<\/strong><\/p>\n<\/blockquote>\n\n\n\n

There may be a slight error in the calculation. But the resulting number is rounded to determine the assay. 24-carat gold can be determined in exactly the same way, but instead of 585, a different metric number, 999, will be used. And it is always possible to determine the other unknown. The metric proof can act as this one:<\/p>\n\n\n\n

\n

Y = 1000 * 24 : 24 = 1000.<\/strong><\/p>\n<\/blockquote>\n\n\n\n

Here 1000 corresponds to 999 in the metric system, which means 100% content of this precious metal.<\/p>\n\n\n\n

24K - what is it: composition and properties of gold<\/h2>\n\n\n\n

24K gold is the highest grade metal. It is the basis for the formation of the country's gold reserve. The material is particularly valuable. But could this mean that it is characterized by excellent strength and other characteristics - no, such properties are not paramount. <\/p>\n\n\n\n

\n

However, all of the physical parameters of the precious metal are taken into account when assessing the appropriateness of its use for other tasks.<\/p>\n<\/blockquote>\n\n\n\n

Density<\/h3>\n\n\n\n

Considering that the 24K (999) precious metal contains mostly one component, only its density value of 19.32 g\/cm is taken as the basis.3<\/sup>. The composition of the material of the highest assay may also include impurities: 0.01-0.1%. Their amount is insignificant, and therefore the density of these components does not significantly affect the performance characteristics of the alloy. The material is stretchable and ductile. This allows you to make the thinnest sheets of gold leaf - less than 1 mm in thickness.<\/p>\n\n\n\n

Durability<\/h3>\n\n\n\n

24-carat gold is known to be extremely soft. On the Mohs scale, this material does not exceed 3 (out of a possible 10). Such an index does not contribute to the preservation of the geometry of products after molding. Traces will be left on the metal if you move a sharp object. From it you can easily get a new product: to forge a thin foil, to make a wire. And the precious metal will hold its shape at the initial stage of operation. But it cannot withstand moderate and high mechanical loads. Other parameters that determine the ability of the metal to withstand pressure, impact:<\/p>\n\n\n\n
