Copper-based alloy properties
PubTime:2018-01-22 Socure:www.brassbush.com Author:
Copper-based to join a certain amount of other elements of the alloy. Medium strength copper alloy, easy processing, fatigue resistance, beautiful color, and has good electrical conductivity, thermal conductivity and corrosion resistance, is a non-ferrous metals, an important branch. Copper alloy is widely used in various industrial sectors, its output is second only to steel and aluminum, which is the third largest alloy category in metal materials.
Copper alloy has good electrical conductivity, thermal conductivity, moderate mechanical properties and high chemical stability, poor cutting performance. With the addition of different types and amounts of alloying elements, the properties of various copper alloys are quite different.
Electrical conductivity
Copper alloy is a good electrical conductor. Pure copper conductivity of 100% ~ 103% IACS (IACS defined as copper). The addition of any solid solution alloying elements will reduce the copper conductivity, the reduction of atomic concentration per unit, depending on the alloying elements of the impact of the lattice of copper in the solution range with increasing the amount of increase.
Color
Copper has a beautiful rose-red color. After adding alloying elements such as zinc, aluminum, nickel, and the like, the color changes to golden yellow and silver white, making it useful for making various decorations and coins.
Strength of copper alloy with medium strength, annealed industrial pure copper tensile strength of about 240MPa. By solid solution strengthening, work hardening, precipitation hardening (including metastable), grain refinement and dispersion strengthening, etc., can increase the strength of the copper alloy. Cold working can either be used alone to harden the alloy or it can be hardened by either precipitation hardening or metastable decomposition.
The addition of any elemental alloying solution in copper increases the strength of the copper. The degree of strengthening of the shear modulus per unit atomic concentration is related to the difference between the atomic size of the added element and copper.
