Is alloy jewelry good ?

There are many kinds of jewelry, styles, and materials involved. The material often used in jewelry are gold, K gold, and sterling silver, among which there is a critical materials alloys.

What are alloys? Is it gold?

Simply put, it is composed of two metals or non-metals. Substances that have metallic properties themselves are called "alloys." Alloys are generally prepared by fusing each component into a uniform liquid and condensing it.

The alloy calls a synthetic metal because it contains various components such as zinc, iron, silver, etc. The higher the tin content, the better the quality of the alloy. In addition, some people have allergic symptoms when wearing alloy jewelry is caused of the "nickel" in the alloy. (But because nickel can make products smoother, shinier, and less expensive, it has always had an equal market share.)

Whether jewelry made of alloy is good, we need to analyze it from two aspects.

Advantages of alloy jewelry

1. Alloys include copper alloys, lead-tin alloys, zinc alloys, and other alloy types according to their material texture and composition. At present, lead-tin alloys are mainly using in the market. Because of their superior properties, such as good toughness, strong plasticity, low melting point, and low material prices, they have brought a strong foundation for the popularization of the fashion jewelry industry. 

2. The alloy has good casting performance and can die-cast precision parts with complex shapes and thin walls. The surface of the casting is smooth; surface treatment can be performed; it does not absorb iron during melting and die-casting, does not corrode molding, and does not stick to molds; good room temperature machinery Performance and wear resistance; low melting point, easy die casting.  

3. The most significant advantage of the alloy is that the price is lower than other metals, which significantly reduces the cost of jewelry, so consumers accept it.

Disadvantages of Alloy Jewelry

1. Not durable

Since the alloy is a mixture of several metals, the composition of the alloy is unstable. It is more likely to be corrupted in life, causing jewelry to fade and rust, and it is more likely to cause human allergies than other materials.

2. It is harmful to the human body

Some people like to wear necklaces, bracelets, earrings, and other alloy accessories. No matter spring, summer, autumn and winter, wind and rain, they will cut on their bodies. Most of the alloy ornaments are electroplated products. If they are often in contact with acid stick salts or soaked in sweat, they will become mildewed, which is harmful to the human body. These trace amounts of dissolved metals such as chromium, nickel, and diamond will dissolve into the blood through the skin and interact with immune cells, resulting in contact dermatitis.

Especially when sweating in summer, the invasion of sweat makes these metals or chemicals and pollutants more likely to play a role, causing local skin erythema, peeling, pimples, blisters, rosacea, etc. Itching and burning sensation. The itching caused by allergies can cause local infection, purulent ulcers, scarring, and hyperpigmentation after the wound heals. There are also some alloy metal ornaments in the production process, high-temperature treatment to change the metal activity, and long-term wear will cause unavoidable damage to the skin.

Therefore, alloy jewelry cannot be worn every day for a long time and must replace regularly.
