Special Alloy

Special alloy refers to an alloy composed of two or more metal or non-metal elements under certain temperature and pressure with special physical and chemical properties and special functions and uses, generally refers to high-temperature alloys, precision alloys, corrosion-resistant alloys, high-resistance electric heating alloys and special functional alloys.

Materials for special alloys include but are not limited to: Nickel based alloy, Cobalt based alloy, Titanium-based alloy, Aluminum base alloy, Copper base alloy. They can be classified according to their composition, usage, material, workmanship, delivery status, etc.

Special Alloy Classification

These alloys can be further classified by their basic properties and basic constituent elements. For example, According to the basic chemical element composition, they can be divided into the following categories :

Nickel alloys

Cobalt alloys

Copper Alloys

Titanium Alloys

Tungsten Alloys

Aluminium Alloys

Iron Base Alloys

Maraging Steel

Magnesium Alloys

More Special Functional Alloys ……

Application of Special Alloys

Special alloys are mainly used in the manufacture of aviation, aerospace, nuclear energy, chemical processing, ships, medical care, electronic control and other parts that are resistant to high temperature and corrosion, and require special physical properties and special functions.

Processes for special alloys include but are not limited to: Powder metallurgy / molten metallurgy

The delivery conditions of special alloys include but are not limited to : Hot rolled state / Cold rolled state / forged / machined / soft annealed / hardened ……
