The differences and characteristics of 5D hard gold and 999 foot gold

The differences and characteristics of 5D hard gold and 999 foot gold

In the jewelry industry, 5D hard gold and 999 foot gold are common materials, and they each have unique characteristics and advantages.This article will compare these two materials from the aspects of ingredients, production technology, appearance effects.

Element

First look at 5D hard gold, which is a alloy containing five different precious metal elements (gold, silver, copper, zinc and nickel).The proportion of these different elements has been accurately calculated, so that 5D hard gold not only maintains the high purity and stability of gold, but also increases the strength and durability brought by other elements.

The 999 foot gold refers to gold products with a purity of more than 99.9%.In the jewelry industry, "foot" means that the purity is extremely high."999" means that the gold content accounts for 99.9%, that is, 999 of each alloy is yellow GOLD.

Craftsmanship

Because 5D hard GOLD contains a variety of different elements and requires accurately controlling the proportion of each element, more complex and precise technical processes are needed during the production process.Generally, vacuum melting technology or other high -end smelting methods are used to ensure a suitable component ratio, and mixing through multiple processes is mixed, and a uniform five -yuan hard GOLD material is finally formed.

In contrast, the 999 foot GOLD is relatively simple. Just add a small amount of high purity yellow GOLD to a small amount of its auxiliary substance into the mixed essence.This is also because its main score is yellow GOLD, and the production process is simple.

Appearance effect

Observation on the outside, 5 d hard G & Old and 999 full G OLD can show high brightness and luster.But because it contains different element,

So they will be slightly different in color.< / p>

Generally speaking, genuine D and luxury national costumes are more luxurious; while they are more warm and delicate, suitable for daily wear.

In addition, D in D also contains the processing of edge polishing or pattern carving, making the overall design more layered and three -dimensional.

Overall, the main types are diversified, and the word -of -mouth economic inspection is significantly improved; then wiping is easy to do well,

It belongs to a practical design.

According to the above comparison, it can be seen that although the five white people are doing very well, they still find problems: 1. Skin cream is too dry; 2. It is too large after washing the steam; 4. Cannot achieve the expected effect; 6. Cannot meet all all all all of them.People need.
