Product Introduction

Dispersion-strengthened copper, also known as alumina dispersion-strengthened copper, is an outstanding High strength and high conductivity copper alloys materials. Utilizing nanoscale alumina as the reinforcing phase, the material is characterized by high hardness, strength, electrical conductivity, and a high softening temperature. Dispersion-strengthened copper serves as an excellent electrode material, exhibiting good weldability with plated metals such as galvanized and nickel-plated steel sheets, as well as aluminum alloys.

 

Feature Of Product

1、The organization is stable without phase transition. High yield strength and tensile strength.

2、High hardness at room temperature, with a small decrease in hardness as the temperature increases, and good creep resistance at high temperatures.

3、High thermal and electrical conductivity. Excellent processing performance

4、The softening temperature can reach up to 830℃

5、The conductivity reaches 85% IACS, and the heat dissipation performance is between tungsten copper (220 W/m·k) and pure copper (390 W/m·k).

6、It has a hardness exceeding HRB 84, high strength, good fatigue and wear resistance, and is an indispensable electrode material for welding galvanized steel plates, nickel.
