Copper alloy with high thermal conductivity

Abstract

The invention discloses a copper alloy with high thermal conductivity, which comprises (by weight ratio) 0.001-0.008% of comprehensive rare-earth metal, 0.01-0.35% of tellurium, 0.001-0.0035% of lithium, and balancing copper.

Description

technical field [0001] The invention relates to an alloy, in particular to a copper alloy with high thermal conductivity. Background technique [0002] Many production devices require heat dissipation. Especially in the field of electronic products, due to the continuous miniaturization of products and the continuous improvement of the integration of electronic components, the heat dissipation of electronic products restricts the development of products. Especially in the field of computer chips, hundreds of millions of transistors are integrated on a chip, and its heat generation is particularly huge. At present, the American company Intel produces the Pentium4 3.2G notebook computer microprocessor, and its power consumption reaches 72 watts, which is equivalent to the power consumption of a 21-inch ordinary color TV set, and the area of ​​the microprocessor is very small, only 9.6 square meters Centimeter, it can be seen how important its heat dissipation is. The curren...
