Jewelry Material


316L stainless steel is very resistant to rust, oxidation, and discoloration. No matter the force or frequency of use, it rarely reveals traces of dents or scratches, even after years of employment. It is often used in marine applications where the steel is constantly exposed to moisture. It is also used in food and beverage processing and chemical processing applications. It is a corrosion-resistant alloy which ideal for long-lasting jewelry designs.

Though people do not consider it as a precious metal, it is much more durable than silver or platinum. 

This durability is due to a Chromium coating that is chemically bonded to the steel. The invisiable coating protects the steel underneath from oxidation (tarnishing and rusting).  It also protects against scratching by taking the initial impact of a scratch and then resealing itself. This process, called passivation, is the spontaneous formation of a hard non-reactive surface film that prohibits further corrosion.

Does stainless steel jewelry tarnish?

Stainless steel is durable and resists corrosion and oxidation. Our stainless steel jewelry will not rust, tarnish, or turn your skin green, even if worn daily. More reasons why Stainless Steel is the best… Unlike many other metals, these are safe to wear and no harm will come if you wear stainless steel jewelry for life.


What alloy is in sterling silver?

Sterling silver is an alloy consisting of 92.5% silver and 7.5% of another metal, usually copper. Pure silver is usually too soft to make anything functional or durable, and therefore alloying the silver with another metal allows it to have the strength of another metal, with the flexibility and lustrous appearance of silver. People use sterling silver to make jewelry, cutlery, and musical instruments.

What is silver alloy?

A silver alloy is a metal that contains silver and one or more additional metals. Since silver is a very soft metal and highly reactive to the air, it is typically used as an alloy.


What is zinc alloy jewelry?

Most jewelry makers will hardly use zinc in its pure form, but they will blend it with other metals to come up with zinc alloys. Some of these casting alloys include copper, brass, bronze, soft solder, and German silver. Accordingly, the resulting alloy will have acronyms such as ZAMAK.

Two of the best-known zinc alloys are brass. People make brass up of zinc and copper, and make nickel silver of nickel-copper and zinc.

Brass, an alloy of Zinc that contains between 55% and 95% Copper, is among the best-known alloys as it is not usually named too many times as a top allergen to earring wearers or other jewelry. It is also known for corrosion resistance, mainly because zinc reacts with carbon dioxide when they come into contact, preventing any further reaction and making the metal durable.


  • Value and cost

Zinc alloy jewelry material is the cheapest and lowest cost. Silver jewelry materials are more collectible.

  • Jewelry process

Silver jewelry is more suitable than zinc alloy jewelry and is easier to set in stone. There are more jewelry styles that can be designed.

  • Skin sensitivity and oxidation degree

Zinc alloys and silver both change color and lose luster under certain conditions. Once zinc alloy color changes, it may cause harm to the human body. Relatively speaking, silver jewelry does not cause skin allergies.


Zinc is cheaper than chromium, and therefore, in general, zinc alloys are relatively less expensive than compared to stainless steel. Though more expensive, stainless steel is a strong, tough material noted for its corrosion resistance. Though some Zinc alloys can be very strong, overall stainless steel is stronger.

When comparing the two alloys per cost, the price of stainless steel is more because of its chromium content. Zinc is cheaper than chromium, and therefore, in general, zinc alloys are relatively less expensive than compared to stainless steel. Though more expensive, stainless steel is a strong, tough material noted for its corrosion resistance. Though some Zinc alloys can be very strong, overall stainless steel is stronger. However, zinc is a heavy element, and when alloyed with other metals it provides better corrosion resistance, stability, dimensional strength, and impact strength. Because of a lower casting temperature, zinc provides a much longer die life which further adds to reducing production costs. When it comes to casting components with tight tolerances and areas with thinner wall sections, no other alloys compare to the zinc alloys.

Ultimately, which alloy to use will depend on your casting needs. In general, due to differences in cost zinc is usually preferred for larger items where aesthetics are less important (outdoor equipment) while stainless steel is most often used for smaller items where aesthetics matter (indoor use and decor).


Both stainless steel and sterling silver are alloy metals, meaning people make them of metals made from a combination of two other metals. People make stainless steel from steel and chromium, and make sterling silver from silver and another metal, which is usually copper, though people will also use zinc or platinum.


All high-tech applications aside, the very characteristics that make 316L surgical stainless steel good for medical use are the same reasons it is such an excellent medium for making jewelry. It may take a little more effort to bend and shape, but the result is guaranteed to hold the integrity of its design for a good long time. And its finish won’t corrode or degrade, no matter what you do to it. It is resistant to rust and other by-products of oxidation, such as tarnishing, which is an unfortunate characteristic of most silver jewelry.


While sterling silver is generally safe to wear, some people still have allergies to silver, nickel, or copper. Some sterling silver jewelry manufacturers will plate their pieces with rhodium to prevent them from tarnishing, but this coating will likely erode over time. Additionally, there are plenty of ‘fakes’ out there – silver pieces that are marked 925, but actually have a higher degree of other metals, like nickel. As with most things, if it seems too good to be true, it probably is. Additionally, people who take certain medications are constantly having to replace their treasured jewelry because gold and silver will pit and discolor in the presence of certain chemicals. This issue is non-existent with surgical stainless steel.


Any accessory or piece of jewelry that is going to be put to a lot of use will last longer if people make it from stainless steel. For key chains, bracelets, pendants, or lanyards, people would prefer surgical stainless steel, as it can take a beating and still retain its finish and beauty.


When it comes down to choosing between the two alloys, a maker will have to select the one that favors their market. Zinc alloys are strong, easy to mold, and will not corrode when people let them out in the environment. They are cheap too and so people’s target here is the larger market. On the other hand, they need a careful combination as too much copper will lead to allergic reactions.

Where zinc is strong, stainless steel is stronger, thanks to the elements that come together to make it. The products which people make from stainless steel alloys can last for years and still look as good as new. They may be a tad expensive, but they are also esthetically appealing.

Naturally, stainless steel is a better alloy when the three are in contrast.
