Hard gold is also called hard gold and thousand foot hard gold. 0.005% of it is added with special metals to increase its hardness, so as to achieve the corresponding hardness. Although the gold content is less than that of traditional gold, it needs more cost in the production process. Therefore, the price of hard gold is higher than that of traditional gold.
The price of traditional gold is mainly the price of gold itself, but in the production process, which does not need to spend too much cost. Therefore, the price of traditional gold is almost the market price of gold. The price of hard gold is different. On the basis of high purity gold, hard gold also has a fashionable style like 18K gold.
In general, hard gold products are more beautiful and delicate than gold products, and the production cost is also higher. This is the main reason why the price of hard gold products is higher than that of traditional gold products.
The difference between thousand foot hard gold and traditional thousand foot gold
1、 Volume weight difference
Qianzu hard gold: using advanced hollow nano electroforming technology, the weight of jewelry of the same volume is only 30% of that of ordinary qianzu gold, which is more lightweight and more affordable; It makes jewelry that looks similar in size much cheaper in price. The utility model has the advantages of low weight, light shape and convenient wearing. (the difference between a thousand gold and gold)
Traditional thousand foot Gold: using traditional technology, compared with thousand foot hard gold jewelry, it is small, heavy, expensive and not very convenient to wear.
2、 Hardness toughness difference
Thousand foot hard gold: its hardness is 4 times that of traditional thousand foot gold, which is equal to 18K gold jewelry. It has high wear resistance, meticulous and lightweight, and is comfortable to wear; Breaking through the limitation of soft texture of gold accessories, it far exceeds the hardness of traditional gold. It is not easy to wear, scratch and deform. It has a stronger three-dimensional sense and is easier to maintain.
Traditional qianzujin: as we all know, the essence of gold is a very soft metal with very low hardness. Qianzujin jewelry and ornaments are easy to scratch and deform without paying attention, which is very inconvenient to maintain.
3、 Differences in style and shape
Qianzu hard gold: the first is the difference between the starting molds. Qianzu hard gold jewelry uses wax model to reverse the mold. The wax model carving is exquisite and meticulous. You can also boldly use 3D modeling to make it fully play in 3D space and have a great three-dimensional feeling. Advanced space dewaxing technology is adopted, with no solder joints and joints, and the surface shape is smoother and more perfect. Give new visual highlights and market hotspots to qianzujin jewelry.
Secondly, due to the improvement of hardness, the design and technology have been greatly liberated. Some exquisite styles can not be made, while the 3D hard gold method can be made. The workmanship is more detailed and artistic, and the problem of inlaying gemstones has been perfectly solved.
Traditional qianzujin: traditional qianzujin jewelry adopts low-temperature metal, i.e. low melting point metal (such as lead, aluminum, etc.) model inversion. Low-temperature metal is not easy to process and carve, and it is easy to leave solder joints and joints. Therefore, its shape is rough, almost all of them are relief close to the plane, with poor three-dimensional feeling.
Traditional qianzujin is a very soft metal with very low hardness, which greatly limits the design and technology of qianzujin jewelry. Some exquisite styles of qianzujin can not be made, which often gives people the feeling of being extensive and lack of artistry. Thousands of gold inlaid gemstones have plagued the jewelry manufacturing industry for hundreds of years.
