Alloy Metals
With nearly 20 years of experience, we strive to provide products that deliver functional performance in the harshest of conditions, whether it’s for sub-sea systems at great depths, aerospace applications at higher speeds and greater payloads, or the aggressive environments found within modern power generation and chemical production plants.
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.
- Nickel – adds toughness.
- Copper – makes metals precipitation-hardenable and increases corrosion resistance.
- Manganese – improves strength and heat resistance.
- Silicon – a nonmetal alloying element that increases strength and lowers the melting temperature.
Alloy, metallic substance composed of two or more elements, as either a compound or a solution. The components of alloys are ordinarily themselves metals, though carbon, a nonmetal, is an essential constituent of steel. Alloys are usually produced by melting the mixture of ingredients.
5 Common Alloying Elements
- Chromium
- Molybdenum
- Vanadium
- Manganese
- Nickel
According to Mining.com, a team of US-based scientists came up with a silver alloy that is 42% stronger than the previous world record. The new metal was developed using a copper micro-alloy mixed into the silver to control the behavior of defects in silver.
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. Brass, for example, is an example of a substitution alloy of copper and zinc.
