How many levels of gold are divided into levels?Analyze the secrets of the goldenness level
The basic concept of goldenness
Golden purity refers to the content of pure gold in gold alloys, which are usually represented by thousands or proportions.It is an important indicator for measuring the height of gold, and one of the key attributes of gold jewelry and investment gold.
The concept of goldenness is critical to buying gold jewelry and people who invest in gold.High -purity gold is usually more precious and has higher investment value and collection value.When making gold jewelry, the selection of purity will also affect the color, hardness and durability of the jewelry.
Common gold purity level and application
In the gold industry, the common purity levels include 24K, 22K, 18K, etc.Among them, 24K gold is the highest purity gold, with a purity of more than 99.9%, which is usually used for the production of gold investment products and high -end jewelry.The purity of 22K gold is slightly lower, about 91.6%, but it still has high purity, commonly in gold jewelry and crafts.The purity of 18K gold is 75%, and it is also widely used in the gold industry.
These different levels of gold are also different in the field of application.Due to the highest purity of 24K gold, it is very popular in the gold investment market.And 22K and 18K gold are more used to make jewelry and crafts, because they also have better strength and durability while maintaining the unique color and valuableness of gold.
Key factors affecting goldenness
Golden purity is affected by many factors, including key factors such as alloy composition and processing technology.
First, the alloy composition is one of the main factors affecting the purity of gold.Gold is often alloyed with other metal elements to improve its hardness, strength, or change its color.However, the addition of these alloy elements will reduce the purity of gold.Therefore, when making gold jewelry or investment products, choosing the appropriate alloy ratio is important to balance the purity and material performance.
In addition, the processing process also affects the purity of gold.In the process of gold refining and processing, impurities or losses of gold may be introduced to reduce purity.Therefore, excellent processing technology and equipment are critical to maintaining the purity of gold, including precise refining processes and efficient production processes.
Golden purity detection method
The detection of gold purity is an important link to ensure the quality and value of gold. Common testing methods include chemical testing, physical testing and instrument detection.
Chemical testing is one of the most traditional methods. It judges its purity through a specific chemical reagent and gold reaction.This method is simple and easy to cost, the cost is low, but it requires professional knowledge and equipment, and the detection time is long.
Physical testing is to detect gold by physical properties, such as density and conductivity.This method does not need to destroy the sample, and the operation is easy, but it can only provide rough results, and it is not suitable for scenes with higher purity requirements.
The relationship between the purity and price of gold
There is a close relationship between the purity of gold and the price of gold. Generally speaking, the price of high *** gold is relatively high, and the price of low *** gold is relatively low.
High -purity gold is often more popular in the market because it has higher investment value and collection value.Investors tend to purchase high -purity gold as an value -preserved asset, which also leads to a large market demand for high *** gold, which has pushed up its price.
On the contrary, although low -purity gold is low in price, its investment value and collection value are relatively low, so the performance in the market may be relatively weak.However, for some specific purposes, such as gold jewelry, low purity gold also has certain market demand.
The future development trend of gold purity
With the continuous development of science and technology, the improvement of goldenness will become one of the future development trends.The application of new technologies and new processes will greatly promote the improvement of goldenness.
On the one hand, new refinement and processing technology will help improve the purity of gold.For example, advanced refining equipment and processes can more effectively remove impurities, thereby producing higher purity gold.On the other hand, the progress of materials science will also provide new ideas for the design of gold alloy, to achieve higher purity and better
