up of two or more chemical elements, of which at least one is a metal. An alloy
has properties different from the metals it is made
of. Most alloys
by melting the metals, mixing them while they are liquid to form a solution, then leaving them to cool and turn solid again.

Ever, what is called Alloy?
Alloys are often thought to be a mixture of two or more metals. However, this is a misconception, as alloys can be composed of one metal and other non-metallic elements. The predominant metal in the alloy is called the base metal. The other metals or elements added to the alloy are called alloying elements.
Beside, what metals are alloys? Alloys by base metal
- Aluminium. Main articles: Aluminium and Aluminium alloy.
- Beryllium. Main article: beryllium.
- Bismuth. Main article: Bismuth.
- Chromium. Main article: Chromium.
- Cobalt. Main article: Cobalt.
- Copper. Main articles: Copper and Copper alloys.
- Gallium. Main article: Gallium.
- Gold. Main article: Gold.
So, does alloy tarnish?
When the plating wears away, the base metal (which is typically brass, pewter, or nickel) will be exposed and the jewelry will most likely tarnish. ... Pure aluminum develops a clear protective layer when exposed to oxygen so it will not tarnish. Aluminum alloys may tarnish. Stainless Steel: Does not tarnish.
What are the 2 types of alloys?
There are two main types of alloys. These are called substitution alloys and interstitial alloys. In substitution alloys, the atoms of the original metal are literally replaced with atoms that have roughly the same size from another material.

Zinc alloy is safe to make jewelry because it is lead-free, and the lead is the toxic substance that makes most jewelry unsafe to wear. When you expose zinc alloy to air, it reacts with carbon dioxide to form zinc carbonate.
An alloy is a mixture or metallic-solid solution composed of two or more elements. Examples of alloys include materials such as brass, pewter, phosphor bronze, amalgam, and steel.
List of Important Alloys and their Uses
|Type metal||Sn + Pb + Sb||In printing industry.|
|Bell metal||Cu + Sn||For casting bells and statues.|
|Stainless steel||Fe + Cr + Ni + C||For making utensils and surgical cutlery.|
|Nickel steel||Fe + Ni||For making electrical wire, automobile parts.|
Common Alloys: The most common and familiar alloys are brass and carbon steel. Brass is made of copper and zinc of varying proportions and mechanical and electrical properties to develop different types of brass alloys.
Unlike other substances that may contain metallic bases but do not behave as metals, such as aluminium oxide (sapphire), beryllium aluminium silicate (emerald) or sodium chloride (salt), an alloy will retain all the properties of a metal in the resulting material, such as electrical conductivity, ductility, opaqueness, ...

Key points: Stainless steels are defined as low-carbon steels with at least 10% chromium with or without other alloying elements. | AISI 4130 alloy steel has properties better than or similar to aircraft-grade stainless steels. | Alloy steels are less expensive and more-easily machined than standard stainless grades.
Jewelers add different metals to strengthen the material and improve durability during wear. The resulting mix of two or more metal elements is called an alloy. For instance, pure silver bends and scratches quite easily. A metal alloy for jewelry, like sterling silver, is a better solution for most applications.
1, Alloy case watch is cheaper. We produce high grade alloy case watches and the look is the same as stainless steel case. 2, With big cases, some people prefer alloy cases because it is not as ponderous as stainless steel case. 3, Alloy case watch is also enough for daily use and water resistant.
Generally, metals can be divided into two categories: ferrous metal and nonferrous metal. Alloys based on iron, manganese and chromium are usually referred to as ferrous metals. Iron-based alloys are called steel. Alloys based on the remaining alloys are referred to as non-ferrous metals.
